runs then cuts out !!!

[drop top vr6 0]

just done a ehgine conversion on a golf 3 cabrio from a 2.0 up to the mighty vr6..

its starts fine and runs fro about 5 senc then cuts out ??

alomost 100% sure i`ve cut out the alarm and imobliser, checked all wires adn sensors etc go to all the correct places on the ecu but now at my wits end

dont know what else to try

any one got any idaes

cheers

Factory immobiliser

You need to have a key that matches the ecu the car came from.

Doubt it. No factory Immob on a '92 vr. Unless your using a later ecu?

[drop top vr6 0]

the ecu and egnine are from the same 93 vr6 and all the wirein

just tried teh vr6 key adn barrel still no good !!??

any other ideas???

93? possibly then. Do you know the ecu code? If it is a immob model then you will need the black box from under the dash and the ring that went over the ign barrel, and the vr key.

there was no black box when i stripped the vr out and no ring around the ing barrel so dont think it is that !!??

its a M9.2 ecu system so i have been told by bosch...

any other ideas ??? got a sparky to come look at it thursday hope he can find some thing???

Definatley immobiliser related, mine does exactly that if i am too quick to fire up and it didnt read the code or if i use a key without a code on it.

[IbiVR 0]

No i dont think it is immob related by the sounds. the early vr's didnt have factory immob on the ecu.

Plus it wouldnt run for 5 secs if it was immob, more like 1.

I guess the only way to know would be to hook it up to diagnostics as they even tell you if it cut out cos of immobiliser.

tried hookin it up to the diagnostics but it would not talk to the ecu or any thoing on the car!!!!

goin to get the alarm system removed and try re codin the keys and see wot happens ... wish me luck
