Hi all , i know its not a nova but was woundering if anyone could help
A mate of mine has got a 54 plate mk4 astra sxi 1.6 petrol ,he's had for a couple of months, sadly when he got it the engine let go 3 days after he got it, he bought a good second hand engine for it, got it fitted on the original engine ECU and wiring loom, but now it wont turn over, all the warning lights stay on the dash, they have plugged in a OP.COM and its coming up with an Immobiliser faut , ( no cummunication ) they have 1 key for the car, They have had, fuel pressure/compression test/and engine timing checked its all ok, does anyone know why there would be faults with the immobiliser after the engine change ? cheers
