it has an aftermarket clifford alarm and immobiliser but these seem to be working fine (before pushing in the little immobiliser thingy she doesnt even try to turn over but after plugging that in she does try to turn over which tells me that its working)

Does the car have a standard immobiliser? if it does, would this cut the fuel pump and spark?

Confirmed thismorning theres no fuel comming through and just one initial spark then nothing. Car turns over though
Waiting to hear from a mate today on how to bypass the original immobiliser
