hi help needed

[Garthy1985]

help needed with my gsi engine not haveing power under load but will rev fine when not moveing i have done the plugs dizzy cap arm checked the earths and the timeing its like its not geting fuel more the a spark problem if no help it will have 2 go a garage :cry:also head has bin done and checked

[mowgli]

fuel filter?
injectors?
if you get the timing wrong, it will not make the power, as the timing on an e16se is also the injector timing.

[Garthy1985]

It had a new fuel filter when i ran it as a 1.2 so didnt think it was that, timing marks are bob on, whats the best way of checking the injectors pls?. Is there any valves/sensors that could cause these problems?

[novasrikev]

do these have the speed sensor on the gearbox like the sri's?

[mowgli]

No.

If the icv is knackered & then someone winds down the mixture screw to compensate, it will run but be gutless... But i doubt it would start properly.

[Garthy1985]

gone out to night and blanked the egr valve off still no better geting a full inlet off a pal 2moz so wil change the lot and try that

[mowgli]

don't change the inlet over, just swap the components

[Garthy1985]

dose this engine have a cam sensor

[Garthy1985]

k do the gsi have a cam shaft sensor do you no

[novasrikev]

no they dont pal

[chimp007_uk]

Is the engine dizzy or coilpack?

[Garthy1985]

dizzy pal

[chimp007_uk]

Have you checked the ignition timing?

The advance might be too far. Will be fine to rev, but under load it will just pink.

[gaz w]

i had this problem with my xe it was the crank sensor

[mowgli]

i had this problem with my xe it was the crank sensor the dizzy type gsi engine does not have a crank sensor. it has a hall effect sensor inside the dizzy that triggers both the ign & the injection.

as we keep saying its most likely a timing issue.

[Garthy1985]

well am goin 2 try all the vavels ect off my spair inlet then if its still not right it will have to go some way to be looked at unless theys any one one here that is round my way that cud lend a hand for abit of cash of course if any one can this is my mob 07907007322

[mowgli]

garthy, if you follow the testing procedure in the haynes book, and all the components are ok (simple multi meter stuff), then its timing, and as other people have found out, timing it by the 'book' isn't the best way at all, this really is a simple injection system. look for air leaks on the intake flexi pipe, check the icv is working ok, the vac hoses are sealing etc. is the spark healthy? as the coils & plugs can be a problem on engines of this age too

[Garthy1985]

must be timeing i have change parts on the inlet still no better also a new fuel fillter last night so do you think i sud alter the timeing on the bottom pully a tooth 1 way at the moment its on the timeing marks

[mowgli]

no ..if the cambelt is timed ok, leave it alone.. the timing of the dizzy is all important on this engine, as it controls both the ign & the fueling. if it is out by even a tiny amount, then it will make a massive difference..


this injection system is actually fairly basic. as i have already said, you check the other electronic components using the haynes book & a cheap multi meter, and you will find out if a sensor is at fault..

coils & amps can break down, too, and under load they simply won't make a big enough spark, so the coil needs checking too.

and also look at the rubber air hoses for splits & leaks, as these can have a massive effect too.

and finally, do you have the warning light connected? is there a light coming on?

[Garthy1985]

checked all the above, no warning lights on the dash, been to a local rallye specialist today he suggested running a direct vac pipe to fuel regulator still no different seem to be running out of options now, have noticed using a hell of alot of fuel also the dizzy is having to be turned quite abit out of the adjustment markers to make it run. suggestions welcome, thanks for help!

[Southie]

Was this gsi engine running okay before you fitted it your 1.2?

[Garthy1985]

i did not see it running thats why i did the head and that

[Southie]

Errr why mess with it though, it might have been okay and you've just broke it.

[Adam]

Simple question that no one seems to have thought about.

What fuel system are you using? What 1.2 used to be fitted? Carb? SPi? What fuel pump are you using?


Stab in the dark right here, the car was a 1.2spi and you are still using the 1.2 fuel pump????

[Southie]

I was building up to that Adam but wanted to get a background on this engine before going into more details.

[Garthy1985]

no i have put a 1.6 16v pump on and i did the cam belt and water pump so thought id do the head gasket plus oil stem seals

[Southie]

Where have you mounted the fuel pump?

[Garthy1985]

in the tank pal

[Adam]

So youve put the pump inplace of the spi one?
Did you remove the 1.6 pump yourself? Definently a 1.6 16v one? They usually have a metal outer case, spi have plastic.

Sounds fueling related to me.


Do you have a pic of the engine/dizzy position? I found these engines will at least run and drive as long as the dizzy is in the right sort of place. Then just adjust from there to get the best from it.

[Garthy1985]

il get a pic now and yea i got the pump out got 1st 1 out of a mk3 astra 1.6 16v then got 1 out of a tigra pal

[Garthy1985]

i have looked at my mates 1.6 spi nova and put the dizzy 2 the same place and mine wont rev up it just pops back

[Southie]

Sounds like fuel starvation to me.

[Adam]

Stupid question but are the ht leads on the dizzy in the right place?

[Garthy1985]

http://i1063.photobucket.com/albums/t512/Garthy1985/seats010.jpg

I know the dizzy looks to be in wrong but its the only place it will rev with out poppin back.

[Garthy1985]

fink the leads r ok as it starts fine

[Garthy1985]

sorry think not fink lol

[Adam]

IIRC the leads should be 1-3-4-2, starting with the top left left looking from the gearbox end.
Top left should be no1.

Its been years since ive messed with one of these engines though
Dizzy looks to be in the right sort of place off the top of my head but cant tell that much from small pics.

[Garthy1985]

sud the leads b 1-3-4-2 wot do you fink 2 pics

[Garthy1985]

do you go round the cap anti clook wise

[Adam]

Heres my old one, the line on the dizzy looks in a similar place to yours..

Btw, watch the text typing... ;)

[Adam]

Looks like looking from above, the "top" lead is no1, and it then goes 1-3-4-2, anti clockwise

[Garthy1985]

that is way my pals is mine is no where near bub

[Southie]

I'm having trouble reading what your putting, Adam I'll leave it up to you mate lol

[Garthy1985]

leads are ok sorry about the tx typing am not very good at spelling lol

[Garthy1985]

ok sorry my spelling is bad as i'm dyslexic

[Garthy1985]

how come you have yours on spi pal

[Adam]

Thats my old spi engine from about 5years ago.

Dizzy setup is same as 1,6 gte/gsi

[Garthy1985]

mine is like the opposite way and the line is not in the adjustment gap

[Garthy1985]

can you see what i mean

[Garthy1985]

http://i1063.photobucket.com/albums/t512/Garthy1985/seats013.jpg

managed to get it bigger, if it helps with anything.

[Adam]

Get them two cast marks aligned, check the leads are in the right place, and go from there

[Garthy1985]

I have had it lined up like that pal,but then it wont rev or drive?? and just about ticks over?

[Garthy1985]

ok will do that then tow it to some one to sort it i think

[mowgli]

http://i1063.photobucket.com/albums/t512/Garthy1985/seats014.jpg

this is massively advanced. the dizzy should be slightly retarded (as in just back from the centre point)

i'm guessing that something else is out of adjustment, like the idle mixture or the co level & it needs sorting.

[Garthy1985]

how can i do this do you no the setting

[mowgli]

your best bet is to get it to a garage & let them spend 1 hr on it.

[Ron]

have you checked your fuel pressure low fuel pressure would cause it to idle but not rev. i would of thought even with your timing slight out it should run drive and rev just maybe not the best also did you put the fuel filter on the right way because a filter the wrong way around can caused problems aswell

[Garthy1985]

yea fuel filter is on ok thanks for the help but as mowgli said time to book it in

[Garthy1985]

Cars still at the garage all timing been checked guy at the garage is now putting in an inline fuel pump, as he thinks theres not enough pressure coming from the intank pump, i hope this works, has anyone come across this??

[mowgli]

You said this was a gsi, i we assumed it was a gsi installation.. I'd be surprised if you'd managed to get it to run without an mpi pump. Did it have a corsa/astra/daewoo intank mpi pump ?

[Garthy1985]

Yea had a mpi mk 3 astra pump in as i could not work out how to put the in line pump in or didnt have a gsi tank and could not find one.

[mowgli]

So your original astra pump should be ok. Why is the mechanic fitting the in line pump? Was there low pressure?

[Garthy1985]

He said he didnt think there was enough pressure, i have tried 2 mpi pumps and its just the same.

[Spudly]

Errr, where is the air mass meter, im not surprised its not running right without it....?

[Adam]

lol
I assumed that was a half finished pic.

[Garthy1985]

yea i have the air mass meter just not on that pic

[Garthy1985]

hi all just to let you all no my car is now sorted it was the in tank fuel pump touching the bottom of the tank and blocking the intake thanks for all the help tho just need a new mot and gsi kit fitting then we should be ready

[Adam]

It did sound like a fuel prob, hence my fuel pump comment.

I never cut my MPi pump pipe down, just bolted it right in. Luck of the draw i guess.
