Hi guys really need some help on this as its going to be the death of me (cut out on an island today :laugh:). My golf keeps cutting out, the lights stay on but the engine just dies. If i turn her back on she fires up but 5/10 mins later it will cut out again. Its mainly when its warm but occasionally when its cold it does it too. I have had new plugs and leads,coil,alternator,dizzycap,had the head reconed and a new fuel pump. Its a 1991 8v digi pb code, any help would be great as i am starting to loose hope. One more thing im new to golfs when i say warm on the mfa the temp reading is about 90 if this is too high i would like to know. Cheers

Is it set up properly?
Also check the wiring to the idle switch on the throttle body isnt snapped, give it a wiggle to make sure as they can break inside the connector
-
Yeah its set up properly it came out the garage yesterday. Will check that wire next. Any other ideas incase its not that?
-
mine was a bit like that a few months ago
check the ECU connector on the slam panel
mine was full of water and green :)
bit of silicon and a really good clean of the contact and shes as right as rain again :wink: :wink:

If you've just paid for someone to set it up and it's not running right take it the hell back and tell them you're not happy with the work!

It will be going "the hell back", its been in and out for the last 2 months to try and find out whats wrong thats why i need some more help.

Has the fuel filter been changed?

That was checked when i had the pump fitted. Just had a look at rubjonnys guide about resetting the ecu taking the blue temp sender off etc. Might try that next. After that running out of ideas :undecided:
-
Problem solved turns out the relay that controls the injection had died put a new one in and the cutting out has stopped.
-
It turns out that the relay hasnt solved it. Although when it cuts out i can still hear the engine is on, the rev counter goes back to 0. The only thing i can say its like is knocking it into neutral and rolling to a stop. Whilst your on the roll if you turn it on and off it is ok again for about 10 mins. Could it be the immobiliser? Also over the weekend i have checked as much wiring as i can access for breaks, nothing came up, and also cleaned all the connections.
Another problem thats also turned its head up dont know if its related is when shes warm and you park up and come back say half an hour later it initially idles at 2000rpm but after driving round it settles back to 1000. I have read topics about the idle valve causing this but this is a newish idle valve been cleaned inside and out it.
The next thing is to wait till thursday my local vw garage has mechanic who has been there for 30 years so hopefully he will know. Any help in the meantime would be greatly received. Cheers.

I had a smilar problem with mine and went through all the things you have did my head in for ages although mine didn't cut out as often it turned out to be the hall sender in the distributor unfortunatley on a digi PB you have to swap the whole distributor took me a while to find one GSF did a recon one but the dont do them anymore so i got a second hand one n car is fine now swaped it and reset timing n runs better than ever now
-
i had a 1.6 and it used to cut out when hot, turned out to be the chip in the distributor! u will need to buy a complete unit, i got one off flea bay, retimed it and was fine ever since

Sounds like it could be electrical/ground. I had a very dodgy window switch, that got stuck on, the engine was still running but the rev counter was at 0, followed by a tonne of electrical smoke. Expensivo.

By ignition relay, is that the same as the fuel pump relay? Could be worth a look if not.

Yes fuel pump relay as far as i know its the same relay as the hooter they were both had 53 on them, i swapped them over intially and it seemed to have sorted it but then it started to cut out again. Thinking they were both broke i put 2 new ones in, again it cured it for a while then its gone back to cutting out again.
Maxp afraid to say i dont have the electrical window luxury thanks anyway.
-
the fuel pump relay isnt the same as the 53 relay, or at least it shouldnt be. You should have a 67, 167 or 80 relay in the fuel pump relay slot (12, bottom right). the ECU relay should be in slot 3 and is numbered 32.
when the car cuts out, do you notice if the fuel pump runs on for a few seconds?
-
ello new to the forum will say yo to all in a bit.
but your problem sound's like a prob i had with my mk2 16v.
now, i'm not sure if you'll have the same set up as an 16v but i'll tell ya any way.
behind the airbox (on a 16v) there's a gray valve if you take that off and clean it up with something like brake cleaner or petrol that might help.
i changed loads of things before even knowing about that valve. it sorted my problems right out.
good luck.

Just been to check and the ones i have been told to change were relay slot 10 and 11. The other 2 you suggested are there d'you reckon i should swap them for new ones? Also the fuel pump if you mean the noise when you turn the key then no there is no noise the only thing that does happen is the battery and temp leds on the dash light up. Its a new battery and the temp is 'normal'.
Neils thanks for the input will look into that within a couple of hours. Love the job and knocks on fridays :grin:
Also been to the mechanic i mentioned he said check fuel pump in boot for buzzing if not apparantly that can starve the main pump of fuel? Also he said when your adjusting the mixture to disconnect the hose to the flying saucer thing and block it up. Will try that as soon as i can. Thinking about it i read that on here so my fault.
-
ok thats not right, next step switch on the igntion and check the isv. if its not buzzing then the ecu is not getting power, which would be the 32 relay.
If you can get known good 2nd hand ones its worth a try, though they arnt that expensive from VW.

Just got back from more tinkering and been outside to try that. Im not sure what its meant to sound like but its quite a loud (can be heard) noise and comes on then off again. Almost like its powering up.
Also on the airbox the 2 little hoses that come of the box and up to the top of the engine one of them (the higher of the 2) was for some reason blanked off and pushed back in. I've took the blank out and the irratic idle has stopped but occasionally does about 3 revs/blips and evens out. If that was blocked would that mean the current mixture is too lean and thats whats making it do the odd irratic idle?
-
are you sure that noise isnt the fuel pumps priming? if it is the ISV something isnt right :undecided:

Im pretty sure its the isv i had someone turn the ignition on and i had my head right next to it and it did like i said. It does sound like the fuel pump priming but surely you couldnt hear that right at the front of the car? Should it be a constant buzzing? if it is is it loud enough to be heard? This is the third isv i have had and out of the 3 this was the best it was the only one that when i had it off the car and put power to it that it sparked the other were dead and made it run dead lumpy. It might sound crude but that was what i had been told to do to test it. If this is wrong or the isv sounds like its dead can you tell me or could it be the 32 relay? Thanks for your help jonny i'd be very grateful if the advice can keep coming everything else keeps coming to a dead end.
I have the fuel pump relay no 83 on order should be in tomorrow as one garage i have been to said it sounded like the pump was cutting out, seeing as i've put a new one in i thought this would be a good try.
-
Been out and put the fuel pump relay in still no luck. Also the vw mechanic gave me a tsi unit? (on top of the ecu) I think thats what he said if its not i've forgot what it was. Plugged that it and thats not causing it. Any more info on the isv would be good if its meant to buzz constantly, i dont think mine is.
-
Tried another isv i have cleaned it and this one buzzes all the time when the ignition is on. Seems to have made it idle better to. Still got no further on the cutting out anyone got ideas?? :undecided:
-
next time it cuts out, listen for the fuel pump. if you dont hear it buzz for a few seconds you have a fuel cut :)
edit: and yes the isv should buzz quietly whenever the ignition is on.
also, was '83' relay a typo? you want 67, 167 or 80 ;)
-
sounds like the same prob i have with my 1p engine in my mk2 at the mo.have changed plugs,leads,rotar arm and dizzy cap.drives perfectly but cuts out now and then when you pull up,also if you rev it up revs go up and let it go and it cuts out,getting enoying now so hope one of us finds the prob,will keep you posted .... :wink:
-
Might have been a typo :rolleyes: i meant 80. The "newer" isv buzzes all the time now. This may help you lemon, had a breakthrough today i put a spark tester (not sure if thats the right name) on a plug and when it/as it cuts out there is no spark. Took this info to one of the guys who has been helping out LOADS and he seems to think that its the chip/unit thats on the side of the dizzy, said hes had problems with these before.

I've had a similar problem on a different vehicle that runs a Motronic ECU. Car would just randomly cut out and take some effort to start again, I changed the speed sensor and checked the usual stuff, earthing points etc for the ECU and so on. Turned the ECU was at fault, have you tried swapping then out with a different unit?
