Title: MK2 Stalling when cold
Post by: dubvrs on 24 May 2005, 23:14: Now my mk2 gti 8v is up and running i have the following problems.

Revs take a while to settle so replaced isv and seams a lot better now.

When cold it takes a while to start (like no fuel) then sometimes starts and dies a couple of times then once it's started to get warm it's ok. somtimes it will start after a bit then run for a minute or so then die. Checked all the vacum pipes and ok.. Ordered a new blue temp sensor but checked and cleaned the connections for the time being.

Once warm the car is fine but takes a bit to start (5 secs or so) then is ok and does not stall. Could one of the fuel pumps be on it's way out.

I have put in new plugs, ht leads, dizzy cap & rotor arm and runs much better but still stalls.

Any ideas.

I had exactly the same problem last week with my 16v. I sorted the problem by changing the fuel filter and plugs. It made a huge difference!!

Hopefully the fuel filter will sort it.

Post by: dubvrs on 26 May 2005, 15:43: Well was looking into it today and the fuel pumps seam to just stop then the car stall so need to find out why they are stopping :shocked:

Only 2 things it car realy be is the crappy laserline imobaliser (getting replaced with a cat 2 friday) or the fuel pump relay.

Is the fuel pump ment to prime everytime you turn the ignition on as mine seams to be a bit hit and miss.

yes it is, and id suspect your dodgy alarm causing it to be hit n miss

if the fuel pump doesnt prime the car wont start

Post by: rubjonny on 27 May 2005, 12:54: Could be the fuel pump relay has had it have you got another one you can swap in? Take a look at the wiring behind the fusebox too if you haven't already, you never know what previous owners have done back there. I found the main ignition live feed from the fusebox had been cut, had thinner gauge wire spliced in for an imobiliser, then at a later date some NUMPTY took out the imobiliser, twisted the 2 ends together and wrapped some tape round it :shocked:

Post by: dubvrs on 27 May 2005, 15:20: I tested the circuit post fuel pump relay at the fuse and was ok. Cat 2 is now fitted and no more problems.

Laserline is now in the bin after i attacked it with a screwdriver :evil:
