Immobiliser problem?

Something is getting warm, expanding then not working anymore.

Coil might have a crack in it?

Mine did the same just before the coil packed up. ( small black box attached to the bulkhead just under the passenger windscreen wiper about £30-£40 )

what engine?

Thought I'd save on posting a new thread, I'm having similar problems, changed my 1.4 engine to a 2.0 16v, swapped over the ecu, chip and Immobiliser ring but still it starts for a few mins then dies then after that it only starts for like a second then dies, I've got a price to just remove the immobiliser from the ecu so this should sort the problem right? If not I dunno what's wrong!

Thanks, Kyle

you have the key that came with the donor engine?

you have the key that came with the donor engine?

yeah, took the chip out the donor GTi key and put it in my original key.

having the immobiliser removed from the ecu will solve my problem?

might not be an immob problem kyle

it is an option, i tried getting it done...PAIN IN THE BEEPPPP not even kidding, no one would do it!

did you get ECU, immob unit, key and ring out the donor car?

also check the earth wiring of the battery terminal, mine corroded and then tore, then i did a bodge job at my mates, and it worked fine, until it didn't start...cos it decoded the immob chip

so they re-earthed it, then recoded key, and i was off

 

[kyle18uk]

true mate might not be!

C2 motorsport are removing the immobiliser from my ecu for £100, i dont think thats too bad and atleast then i can cross that off my list and if it still does it i can look at other things.

Yeah I got the ECU, immob unit, key and ring out the donor car, thats why its a bit strange, but ive been looking around and it seems like an immobiliser fault as it only starts for a few seconds then cuts out.

I dont think it will be my earth off the battery as I moved my battery to the boot with all new cables and terminals.


Its a strange one, just hope having it removed works or it could get expensive!

well my problem is sorted it was the fuel pump relay
