Hi there

My vectra was off the road nearly 8 months. My battery was dead so got the new one but still could not start the car. I can hear the solenoid click. Pulled the starter motor out cleaned the brushes worked fine on the bench. Put it back in a car same thing, motor turns 10mm, battery ok, tryed jump starting but no luck. Keys opens and closes the car.

Can something be wrong with immobilizer due to a no power to ECU for long time.
