My car wont start and stay running!

[VR6]

Had the same problem (fires and then dies about a second later) disassembled the ignition barrel with out much success. Cars with the auto sparky now. Apparently the engine ecu ignores the immobiliser signal, hopefully this doesn't cost me a fortune.

Reading over the posts in this thread, not sure if my issue is the same?? Cause mine starts up first time every time, however, its a delayed, laboured start :l it takes a few seconds more than it should and kicks over, but only just. Anyone had this issue?? I took it to the mechanic, he diagnosed it as a faulty coolant temp sensor, saying that it was injecting too much fuel on start up than it needed. He put the new one in on wednesday, but its still happenin!

Any ideas?? Again, not sure if this is related to what you guys are speakin of, as it sounds like you guys take a few attempts to start??

Cheers,

Simon.

My money is on the reader coil, or the chip in the key. Do you have another key?? Try it if you have one.

Wait - theres a chip in the key?? Thats not good I take that thing in the water surfing!!

My black plastic housing falls apart all the time around the key, I have never seen a chip in there??

not all mk3s have the chip for the immobiliser in the key
my white one which is a mid 94 doesn't but my old grey one which was a 96 did
not sure if it was an option for early mk3s and was standard on later mk3s ???

I'm pretty sure the earlier ones didn't have it and the layer ones had as standard. My 97 gti had it to but my 94 vr doesn't. Even the instrument cluster differs slightly on the pre 95 models.

So no one knows what this could be?? Kinda desperate to figure it out im not sure how this could be a reader coil or anything related?

I've had this happening to me off and on for over 2 years now, it is very annoyying but I find it funny more then anything else. So far... it has not got me into any trouble, besides leaving me stranded in a country town for a few hours on a camping trip once!!

I have had my entire immobiliser rewired and replaced so far, at some expense. The issue still occurs, now with a brand new immobiliser and fresh fobs. I have often wondered if it is the reader coil, how much are those to replace??
