ive got problems starting my 1.5 diesel van and i believe i have traced it to be my diesel pump anyone know of a way to rebuild it at home or is it a definate specialist job or replacement pump if so any suggestions for a supplier near the cambridgeshire area

there are enough bosch diesel injection places about.. but get your injectors checked too

or put a wanted ad up on here for a s/hand one.

i know its not local, but Diesel Bob in preston seems to be a genious, and reasonably priced as well. usually has all the spares to rebuild, and sends the stuff back to you pretty quick. we send all our diesel stuff to him from work, injectors, pumps etc, even had my dads mondeo injectors rebuilt and recoded for a very agreeable sum

took the feedpipe from filter to pump off covered the hole with my fingers and got a mate to turn her over to find no sucking

mowgli

take the return pipe off, reconnect the feed pipe & try it. diesel injection pumps aren't exactly like an airport fire truck, they only suck a tiny amount, and it takes ages to bleed a bosch pump thru after a filter change

Rage
10-03-13, 12:30 PM
by return pipe you mean tank return pipe? i haven't changed the filter as yet it was going to be my next thing to do. seen as i can't get one today is there a way of cleaning it enough to get a cough from the engine? just to confirm it is the filter thats blocked

mowgli
10-03-13, 12:41 PM
its more likely the filter than the pump.. it is actually quite possible to get the filter so blocked that it will run the pump totally dry.. we had it with a 16 ton excavator fitted with a large 4 cylinder isuzi engine (basically a very big 1500), and had to prime the pump with grease (a very old trick) to get it to pull diesel up the lines.

Rage
10-03-13, 12:51 PM
hmmm ok so how would i go about priming the pump if i change the filter. as far as i'm aware the filter has done 72000 miles. i'm going to get a new filter either way. and why would i not get any suction when i put my finger over the pumps intake?

mowgli
10-03-13, 12:54 PM
like i said, if the innards of the pump are dry, it simply won't suck, gear pumps don't pump when dry, they need priming. pour some fuel down the pipe into it, it will only take a tiny amount, like a few cc's of fuel.

i can't remember if the filter is a spin on mounted vertically, but if it is, you can fill it up too, it will help to get the pump filled quicker

Rage
10-03-13, 01:12 PM
when i took the pipe off that goes from the filter to the pump i could see fuel at the top of the filter so i know that is filled but the pipe didn't have anything in it i then replaced the pipe onto the top of the filter and took the pump end off and there was a little bit of fuel in the pump and as my mate cranked her it dissapeared into the pump and didn't return. then i put my finger over the pump intake hole and my mate cranked her and i couldn't feel any suction again. this is what leads me to believe it's the pump. but i'm hoping it's not as it looks a right cow to get out to replace it or get it reconditioned. i have found this EBAY LINK REMOVED so i could recondition it myself but i wouldn't know if anything is broken inside the pump if i do take it to bits.

the filter sits vertically on the drivers side inner wing by the strut top. pics to follow just waiting for them to upload

Fit a piece of clear pipe between the filter and pump, and if you can get one, fit an in-line bulb primer too. Makes priming a fuel system soooooo much easier, and the clear pipe enables you to see if there is air in the system.

Once fitted, crack the injectors and pump the primer while your mate cranks it over and see if you get a good amount of fuel coming through. Also, to eliminate a blocked filter from the equation, simply bypass the filter and try run it like that.

sorry, but any number of things in the fuel tank can kill a pump. water & rust for a start.. you might have been very lucky, or have particularly clean diesel in your workshop, but i'd never recommend it.

i'll get a new filter as it was on my list to be replaced next anyway then i know it will not be blocked and if she starts i know i can leave her instead of disturbing the fuel system again to put the filter back in place. is there any particular way of ensuring i have no blockages in any of the pipework. my mate spoke to his neighbour who used to deal with plant diesels and he said about using an airline to blow down the fuel line to the tank and if we can hear bubbling in the tank then the line is unblocked but again i have the problem of the banjo connections to do this.

i've played with a lot of diesel engines.... its a farmer thing... we also have an ancient hyster forklift with a perkins 4 pot in, & the fuel tank is part of the chassis, so its impossible to remove without dismantling it.. it is also prone to sucking crap up the pipe.. usually when its too far from the air line to fix it quickly... so improvisation is the order of the day...

10-03-13, 05:32 PM
We had a combo 1.5td in a long time ago which wouldnt start. Turned out to be the filter housing at fault, it was drawing more air through it than fuel. So if you still cant get it going and cant fit clear pipe to check for air, try another filter head if you daren't bypass it.

Rage
10-03-13, 06:40 PM
one thing i have found weird is that i'm getting exhaust fumes out the tailpipe and there was no fuel when i took the banjo of the filter. surely if i'm getting exhaust fumes there must be fuel?

staggy_gsi
10-03-13, 06:49 PM
If theres air in the system, it will be getting fuel but not enough to start it. Same applies to a blocked filter. Does she fire off easy start?

Rage

oh didn't know that :wall: i will definitely give it a go then. presumably if she will cough with easystart then that will help her drag some fuel back through and hopefully get her running again?

mowgli
10-03-13, 07:51 PM
we have a daf lorry that when it gets left for a few days, it sometimes drains back leaving air in the fuel line. there is a hand primer, so it gets a couple of minutes of pumping, then if it doesn't fire, the easy start is used, and it does usually fire up, a main dealer mechanic showed us that trick. use it sparingly though

meritlover
10-03-13, 09:33 PM
Bradex kills diesels. Once you use it a few times it will need it for ever. The stuff detonates and wrecks the rings, plus people start to rely on it rather than fix the root of the problem.

It does sound like a priming issue. It would be odd for the car to drive in one day, turn it off and the pump simultaneously sh1t its self. But not Impossible.
Change the filter, prime everything, crack the injector fittings and crank it til the fuel comes through..re tighten and it should fire up.
Did the 1.5t not have a hand plunger pump or am I confused? I thought it was on the filter housing but from the pic it doesn't look like it.

ML, the whole ethanol kills engines thing is a bit misleading, as in canada, and arctic countries, a lot of vehicles come with an ethanol injection kit form the factory. my wife's uncle is in the chemical industry in the US & he contacted me a couple of years ago to see if i could point him towards any easy start manufacturers cos he had a load of it to sell.

people used to say you shouldn't use the choke, cos cars get addicted to it!!!!!!! so what do efi cars do?? they have a warm up cycle where they add more fuel...

most bosch rotary setups on cars & small plant rely on the pump to self prime.. but the Bay has loads of 'inline primer pump's listed for not much coin.

Rage
12-03-13, 03:07 PM
i'll only be using it to hopefully get her fired up this once. virtually everyone i speak to says its air in the fuel system so the easy start should get her to drag that air though and run on her own diesel then i won't need the easystart any more

it will be fine. it just shouldnt be relied upon. Use new copper washers on your banjo's or aneal the old ones.

16-03-13, 05:13 PM
Make sure your leak off pipes are all up to scratch too, if theres any which look like theyre starting to perish or leak etc get em replaced!

If all else fails and its still not cured, you could fit one way valves in line. As close to the tank as possible, its a cheap fix and it works

now she wont run using easy start to start her and when she does she needs throttle input to keep her alive and she runs real lumpy

Yeah mate thats them, forgot theyre metal on those lumps tho. Injectors been out lately? Them metal leak offs can crack when disturbed. Im just trying to think of possible causes now lol. Id be tempted to fit one way valves in the feed and return and see if it cures it

Rage
17-03-13, 09:30 PM
injectors have only had the top union taken off to see if there is fuel getting to them and there is. i have not disturbed the injectors in any other way.

where can i get these one way valves. would i be able to fit an inline fuel pump on the feed end to make sure there is fuel getting to the mechanical pump? im just thinking if there is no fuel at the pump it won't have anything to pump so i would get the fuel starvation problem but if there is an inline pump to get fuel from the tank to the filter then the mechanical pump has fuel there to do its job?

They do different sizes. We keep them in stock at work i think, we do use them quite a lot.

17-03-13, 09:52 PM
Fitting a valve is not a solution. something has changed or failed.

you say you cracked the injector unions to see if there was fuel and there was? so why do you think there is still a fuel issue?

staggy_gsi
17-03-13, 10:00 PM
Yeah them priming pumps are ideal, we stock those too. But if the problem is somewhere between the fuel tank and the filter head, it wont solve anything. Thats why we fit them as close to the tank as possible so almost zero fuel can leak back.

Meritlover, its a cheap fix without spending a fortune replacing bits, thats all.

Have you tried running it straight from a can full of CLEAN diesel? As in straight to the pump?

I've had problems in the past with the fuel filter body moving as I've replaced the filter. You need to take the whole filter off of the strut top and clamp it in a vice, undo it all and check nothing has twisted/moved.

I always replace the fuel filter by removing the whole lot now.

can't see any problems such as split pipes or corroded/perished pipes and i'm getting the pump as a back up more than a replacement it's the only one i have seen since the start of this problem so i'm thinking that it will be easier to have this one i'm getting refurbed ready to be switched over instead of having to strip mine out first and if i get mine working then i have a known good one on the shelf aswell. i have a habit of collecting spare parts ready for something to break. i just haven't yet mastered which parts to collect lol.
i also have the correct haynes manual coming so that should help things.

really appreciate all this help guys.

is there any form of filter around the tank or is it just the one in the engine bay i'm wondering if i should take the filter feed off and drop it lower than the tank to see if any fuel comes out because surely if there is no fuel like that then that would be my problem (my gauge states just over 1/4 tank). if fuel won't come out like that then it won't feed the filter so that would be a good check for the feed line wouldn't it?

staggy_gsi
20-03-13, 09:51 PM
Not a filter as such, but the pick up in the tank may have like a gauze on the end of it. These can fill up with sludge and stuff, especially if run on 'cheap' fuel. Another way to check for fuel starvation is to fit one of those hand primers. If it doesnt refill when squeezed then you have a blockage. Similarly, if it feels like its filling too quickly and not chucking much fuel out, its drawing air in from somewhere

very true no fuel is cheap nowadays or do you mean red diesel. my van has no access to red, and it's an ex county council car so i don't think it has ever been run on red. plus i have used a dose of redex for a tank about 800 miles before these problems so i shouldn't have any gunk problems but it's always worth a look

for anyone who still doesn't know... red diesel is the exact same stuff as derv, but with a red dye chucked in at the point of filling at the oil terminal. cheap diesel is the stuff from supermarkets, simply cos it costs less...
petrol on the other hand is a bit of a minefield.. supermarket stuff is usually lower grade than a decent 'known' brand, and gives less power & worse mpg

meritlover
21-03-13, 01:17 PM
Fuel from supermarkets is exactly the same grade, the only exception is that isnt blended with the same high-tech additives like optimax/ultimate etc

The base stock is every bit as clean as 'branded' fuel.

There is more chance in getting sludge from a 10 year old Shell garage than a 5 year old Tesco but even then, the quality of fuel in the UK is very very good.

bio diesel would be ok in a nova diesel engine... modern common rail ones need to be designed for bio to work for any period of time..

stuff in a drum bought for cash is probably full of crap, but filter it & leave it to settle & it would probably also be ok

staggy_gsi

Yeah a nova diesel engine would run fine on it. I was more meaning the fact that over long periods of time, it can clog the gauze in the tank, and indeed the fuel filter should be changed much more regular if run on bio.
As for red, apart from being illegal, its not suitable for common rail systems over a prolonged period of time. The dye makes it ever so slightly more 'abrasive' so to speak, and it does damage the pump which in turn damages the injectors.

Anywhoo, going slightly off topic here lol

interesting.. agric systems will be much higher flow to a car system.. i'd have thought its more down to contaminants in the cans they are using... we had an incident where some alloy wheel cleaner was not cleaned out well enough from a 5 gallon drum & it killed 2 injector pumps

God knows what it is, ive always been told by my boss and a couple of other diesel specialists its down to the dye....

Theres a place not far from me where you can buy it straight from the pump, but obviously people dont stick the nozzle straight into their tank so i suppose it could be down to the drums their using too.

there is a story about a local large supermarket cold store.... for several months, an agency worker was filling up the derv tanks on the fridge wagons with the same pump he used to fill up the thermo-king fuel tanks.... so the whole fleet was running on red!!!! every little helps i suppose lol lol lol

how would i check the feed from the tank to see if there is gunk there. would i have to drop the tank? or is it as simple as pulling the line off and taking a look? i really need my van now just checked the mot on my cav and it ran out yesterday :wall: and my vans mot runs out middle of next month with the tax ending end of next month :wall: really in the stuck now

Disconnect the lines and blow them out. Doubt the lines will be clogged tbh though

take the lines off the tank and stick it in a can of clean fuel

still yet to try anything (damn wet snowy weather) just had a thought would a blocked tank breather cause any problems with fuel draining back? i'm thinking along the lines of there being a vacuum caused in the tank from the vent being blocked and so the fuel isn't draining back it's being sucked back? if so where would i find the tank breather and can it be cleaned or replaced?

its a long shot.

Surely the easiest way to prove it would be to remove the filler cap and test?

it only fails me once ive had it running and it's stood over night so i can't test that while its running.
i've got my hand priming pump with one way valve so i'm going to hopefully fit it tomorrow and see if i can get her to start without easystart and hpefully get rid of this problem once and for all. i'm also thinking of replacing all the fuel lines soon aswell as i've found some decently priced goodyear fuel pipe on the bay so i'll be renewing everything possible to cure this and to keep it gone. as much as she has only done 72000 miles she is still 20 years old so time must have attacked the piping in some way so with decent new pipes soon she can't complain just need the time, light and weather on my side to get them all measured up including the banjo connectors so i can get them all ordered.

technically, any vacuum in the tank would act equally on the suction and return lines. Unless you had an air leak at the front somewhere then you wouldn't be able to induce a reverse flow.

OP about the banjo unions.. the fuel lines from the tank to the engine will be very low pressure, and if you cut the outer crimped piece off the unions with a hacksaw, the banjo end can be reused with a jubilee clip or similar to save you money

nice didn't think i could do that i was looking at getting new ones from the bay along with new hose and remaking every bit of fuel line possible just to make damn sure that it's not the pipes causing the problem

is this still going on? lol

Just buy 5 litres of diesel in a jerry can and stick two short hoses straight onto the flow/return and the other ends into the jerry can

lol fed up of the crap weather stopping me sorting her out so i got this huge gazebo today and put the priming bulb on her found that the new copper washers on the pump end of the feed line from the filter was leaking slightly so renewed them again and rechecked everywhere for any signs of leaks didn't find any so tried starting her but could only start her on easy start so took her for a run to the petrol station and put £20 in to see if that will help just been back out to see if she will start when she is cold and she did so hopefully she will start in the morning

Do the glow plugs actually work?

have you pulled out each one to check it glows?

i dont understand how it cant prime with easy-start but not by cranking.

i'm guessing you meant this..i think its a combination of low battery power & the speed of cranking the easy-start gives it.

yes thats what i meant.

because....

The nova was designed to be self priming, hence why id didn't have a hand prime pump on it. The injection pump includes a lift pump for this very reason.

i've solved it finally after getting my new 'garage' i set about rechecking everything and put the old glow plugs back in and she fired up with 2 cranks so now i will be getting a refund on the new glowplugs and sourcing some better ones. the ones that have caused all this headache are motorcraft ones from ebay they lasted 150 - 200 miles.

cheers for all the help guys really appreciated just hope i can be of this much help to you all at somepoint
