Hello. My name is Mark and I will be assisting you today.
The first thing you need to check is if the immobiliser led is still on or flashing when you insert key in the ignition.
sorry I was wrong
Immobiliser LED flashes when key removed, it is on STILL when I turn on ign, then goes off with relay in engine bay - presume glow plugs also go off after pre heating.
LED beside Engine Systems Fault stays on, what is this LED?
The immobiliser led should go off when you switch ignition on and before you crank the engine. If it does then the key is being recognised. If the led does not go off or flashes then the key is not being recognised and the engine will not start.
Did you have the key in the ignition when you replaced the alternator?
no I don't remember that I had. is it possible to reprogram key to car?
Does the immobiliser led go off after about 3 seconds?
the immobiliser is at top of dash correct - if so this led goes off after 3sec
Hello Mark, any other ideas?
