Hi guys. So I've had 6 MK3 Golfs in total. I had a silver estate for about 2 years that was originally a 1.4 Petrol (Living in Ireland) that I swapped to a 1.8 8v Petrol from a donor car. I drove around it for a little over a year just as a beater car. Early last year, I decided to scrap the shell as it was rusty. I picked up a very clean metallic red hatchback, once again with a 1.4 Petrol. Before I scrapped the estate shell, I removed the engine/trans, axles, ecu loom, ecu and the clocks.
I just finished swapping the 1.8 into the new hatchback shell. Have the basics in, engine/trans, ecu loom and ecu. No coolant hoses or anything as I just wanted to start her up since I did a head gasket/timing belt whilst the engine was out. Sooo, the lights come on, engine starts for about 2 seconds and dies. If I hold down the gas pedal, it will rev when started but again, dies in 2 seconds. Many people told me it would be an immobilizer issue.
I am using the 1.8 ecu with the 1.4 key, immo chip/box. I don't remember swapping out the immo in the previous swap (unless I did) soo did I f*ck this up. Should have I kept the little ring around the key barrel and the box? I have the key with the chip from the previous car, swapped the chip but still the same. Do I need to source all new ecu/keys/ring or can I still make this work? Thanks very much, really need to get this going soon!!
