Non start question...

[overdrive]

Hi folks!

Just completed a clutch change on my mk2 GTI. Now thats done we're back on track for a reliable daily driver. New driveshaft bolts are all im waiting for (VW parts say it wont be here till FRIDAY! Meh) So while waiting i thought i'd double check all was working and the clutch is done right so i tried starting it. No go sadly. First few attempts identified that i'd cracked the tip of the king lead in the coil, so i changed it out and tried again. No go, and the engine was now locking on the second or third turn. By this time i was now noticing that the fuel was constantly priming, and not hitting cut out. Also, theres a fair reek of fuel but no visible evidence which shows a leak. My guess is that the non start due to the king lead has caused a fuel flood, but i cant work out why the fuel is not cutting out after a few seconds. Added to that theres a strange clicking noise from the inlet manifold around the fuel rail AFTER i have attempted to start it. The biggest puzzle is why it has started doing this when i havent been about that part of the engine during the clutch change?? Can anyone shed some light on this problem? Im now stumped!

sorry to say i think you have done the same as i did

Ah tits, that sounds like exactly whats happened. The earth to the box was thoroughly bolted in right, but i now have a memory of shorting the battery out on the gearbox (using a crowbar during the clutch change and it popped out and touched the positive). It sparked a peach too, reckon that may have toasted the ecu?

maybe but i would change the earth strap and ECU

drop the oil out of it too

i got about 20ltrs of petrol out of my sump

Excellent, i think thats exactly whats happened. Bah. I'll try the earth strap tomorrow as i might get away with it and i have nothing to lose! Seen an ECU on fleabay for a tenner so cant hurt to get that bought either! I picked up a new filter yesterday to do an oil change once the clutch was done, so im glad i didnt do it just yet! Will drain it out if it doesnt start tomorrow too. Cheers for the speedy reply too!! Will let you know how i get on.

make sure the numbers are the same on the ECU

mine was a special one as my cars got a lambda probe

Yea, i gathered that from your thread! Looks like you had fun with it! Will make sure tomorrow then that its the correct one before i buy it..

Just checked my ECU today. I have a Digifant II ending in "DB". Is this reasonably common or similar to the other ones found around?

dont know fella

if you have a friendly VW parts man he will give you all the newer part numbers that will fit

try looking on flebay for them

i bought a new one from the usa

perfect

DB sounds very familiar. That is what was in both my 8v's. Don't buy one from a Corrado G60 though. They are different and have a small tube that senses manifold pressure. I don't think that will work on a digi 8v.
