Still cutting out

[DubJoey]

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

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.

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 

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?
