Hi everyone I need your advice please. I work in a body shop so we have dealings with insurance cars that come in after total loss. I usually only go for astras but when this car came in I thought why not. It looked simple enough light front end damage rads, front bumper and lights a straight forward repair.this is where I hit a snag, since I had the car it's never started, but I thought this was to do with the crash, I am now learning that it's not. I have replaced the dash, rads, etc, but the car still isn't cranking when I turn it over. All lights on the dash are off apart from the glow plugs, and the battery light and all other electrics are working in the car so we can rule out battery problems, the plugs are ok and there is diesel in the car. I have had 2 diagnostic men 1 couldn't communicate at all with the ECM and the second one managed to communicate through the instrument panel however his machine could not recognise the ECM. It did clear faults in the cim and and the bcm but it still made no difference as to what the problem is. I have now been informed that following a crash these cars have some kind of cut off switch and the car has effectively gone to sleep ie the main ecu is not communicating with the ecu's hence the car not starting.
I am just wondering if anyone else has had experience of this as I am scratching my head, or knows anything about it.
