As copied from Turbobricks:


Hi guys, I am having a nightmare since swapping this LH2.4 B230FK into my 1984 360.

Here's my latest issue. The car is difficult to start, it will usually just turn over with no attempt to fire on the first attempt, then any attempt after that will usually result in it firing up but cutting straight out, before even having a chance to idle. When i eventually get it away (sometimes requires a little acc to balance it out before it will idle) it sounds as though it is running on 3 cylinders. It feels like it is too!

The car will then drive very crap, stuttering etc until slightly warm, then it will behave normally on very very partial throttle. Anything else and it will do the above.

I initially thought it was, but having tested it I now know all 4 are working fine. as well as testing for a strong spark and testing the coil, I have tested the TPS and the AMM. All are well. The injectors seem fine, and no leaks from inlet or IC piping.

I have replaced the following:

CPS (due to it previously melting on the EGR pipe. I repaired it but thought maybe it wasn't sufficient.) Also, 3 of the wires from the loom were damaged, but re-soldered. I'm not sure what they do as I never traced them back.)
plugs
HT leads
distributor cap
rotor arm
EZK module/ignition amplifier (due to a previous need)
oxygen sensor, gen Bosch.

The replaced parts are between 50-800 miles old, so should be fine.

The o2 sensor was the latest purchase. I was pretty convinced it was at fault given that i was getting no reading from the multi meter, and the car ran the same with it unplugged and everything else ignition related etc has been replaced.


I am yet to test the CPS. How do I do this?

Also, since the engine has been swapped into another chassis, I do not have the OBD plug working at present. I attempted to read the codes but it says no vehicle found.

Any ideas guys? My exhaust is pretty crap ATM, and blows on the join from downpipe-turbo. Could this be playing a part? I haven't had a chance to improve it yet what with blowing oil returns off and general non-start issues. It's a stock B230FK with the EGR removed. (I found removing it caused no issues, and then a couple days later this problem surfaced)
I would reinstate it, but I cut up the pipework.

The car runs the same with the o2 sensor unplugged, knock sensor or CTS. Surely this isn't right?

I am sick as hell. I was hoping to be running 12psi by now.

One other thing. I am currently running a smaller fuel pump than specified, but it has been fine for weeks now (since the conversion) I have a B230 OEM spec one to fit but am waiting on a few fittings. Surely if it was the pump at fault then it would just stop altogether? Removing the feed from the rail and priming the pump it seems to flow as much as it ever has. I want to get the new one on to rule this out. Is it possible to pressure test all rails? Mine doesn't have the valve on it.


Thanks, Liam.

fuel pressure reg or pump. its lacking fuel.

[L14MNP]

How do you test the reg? Pull it off and if there's fuel in the vac lines then you know?

[MK999]

You're using a pump you know is wrong and trying to diagnose a fault... get that fixed first and see what it does, otherwise you might swap something working for something new/DOA and end up with a more complex problem than you started with.

[Sloth]

i had the same fault on a 2.0 8v nova with a 1.2 spi pump and a fubar reg.

[Sloth]

just a thought does it run a rotary icv? theyre prone for dying too....

[L14MNP]

MK, the pump grafted before though. It seems odd that it would just stop delivering enough as opposed to dying completely. The reg sounds plausible. i forgot that it was on my list to check. How do you check it then Rob?

I'm not too bitter about replacing the other crap. Technically it's all service parts anyway.

[L14MNP]

just a thought does it run a rotary icv? theyre prone for dying too....

I'm not too clued up on that and can't find much info on them. All I can find in that area is below the TB and T's into the intake pipe.

There's a surprising lack of basic service and repair info on Tbricks. i may have to join Brickboard or Swedishbricks.

[Sloth]

l 2.4 is basic at best, its the components that die. iirc the icv sits on the inlet side of the motor under the inlet. round thing like the vaux ones. as for the fpr just try another one from the scrappy, its a pocket part.

[MK999]

Ahh didn't realise your pump was working at one point. Does sound fuel related.

[L14MNP]

Dude I can't find any in the yards now. :( When I went looking on Saturday for a TPS there was nothing. Granted I only tried two places due to time, but it's getting the same story everywhere now.

I need to find out how to test the ICV, all I know is where it is. lol Under the inlet as you say.

[Southie]

What colour have your plugs gone? Does it appear to be running lean??

[L14MNP]

Oh yeah, important info missed out lol.

The plugs I removed were a little black, but not uber black like it was running rich. The current ones are the normal healthy grey/brown colour.

When I removed the o2 on Sunday it was white, today it was jet blac, but I did run it back home wothout it connected. :/

[Sloth]

if the o2 is disconnected it runs rich as a safety, i know there is a few ovlov tubbys in upullit, worth a try? plugs seem fine, to test the icv, remove, and fit another. :D

[MK999]

Dude I can't find any in the yards now. :(

You wanna try down here, theres funking ONE yard I can find local and most corsa b's dont even survive the cut age wise :(

[Southie]

Anything here parts wise that may help? CLICKY (http://www.probedistributors.co.uk/Category.aspx?s_vm=VOLVO&s_vmod=940%20II&s_vs=2.3%20ti&s_ec=B230FK)

[L14MNP]

Gotta run to work now. Ordered a FPR from Pages, will collect/fit in the morning.

Cheers for the links etc lads. :thumb:

[Lee]

No mention that you have checked the timing?

[Sloth]

reckon its slipped lee?

[Lee]

reckon its slipped lee? No Idea, just looking at his original list of stuff he's checked, timing wasn't on there, and it could certainly account for most of the symptoms. Just worth checking IMO

[L14MNP]

I thought I put that as a possible in the original post? I haven't checked it no. Don't have a light. :( I ordered a belt from eBay and it never arrived. Was just gonna take care of it when I fitted the new one (before the probelms surfaced).

I will need to borrow a timing light. Would it still idle fine though?

Needless to say, the FPR wasn't at fault! :(

[Sloth]

just check the timing marks are in the correct place mate and the tension is right.

[L14MNP]

Haven't got time now. Will have to be tomorrow. FFS.

On the way to/from getting the FPR the car cut out three times when coming to a stop, another FPR 'symptom'. So I cannot believe the POS is still the same!

[brainsnova]

ive got a timing gun i ll shine it towards your house at 6.30

[L14MNP]

LOL. Cheers :P

I've arranged to borrow a mates tomorrow. Gonna order a belt now also.

ARGH! I only had 4psi and even that has been taken away from me! :( lol

[brainsnova]

its annoying when in the old car is was :thumb: and now all the headaches

[L14MNP]

You said it mate. TBH it was running fine in the 360 too. This is such a crazy issue. :/

[L14MNP]

Timing lines up. I ordered the banjo to fot the uprated pump.
