Mk5 gti starting issue
r5gtt:
Plugs could also cause the problem if thr vehicle hasnt had a plug change for a few years so best check plugs and coils first if you haven't already done so.
Those are the basics tbh.
Clgale1988:
Ok i will have a look got no record of plugs or coils been changed on it
Clgale1988:
What spark plugs do they take?
Beej:
I have changed plugs, coil packs, fuel filter, had inlet cleaned and runner flaps removed to see if it was any of them, nope no joy. Tried priming the lpfp a few times also, no joy.
I know what you are saying with regards to not doing it was it's been run. It will start perfect if it hasn't been sat for 7+ hours.
To me it seems like a fuel pressure dropping issue, since it's only really apparent after long stands
Clgale1988:
Il start with the basics for me 1st iv not long brought it and its always been there so want it sorted its done 100k now and cant find nowhere says coils been done plugs been done etc
