Another vehicle problem, when will it end.... Went out this evening to pop out after the car having Been stood for a few days which it always is between drives recently. car turned over started as normal but almost immediately cut out, it now won't start again, initial thought was *** timing belt snapped but have taken oil filler cap off and camshaft is turning so belt is still in one piece, it is turning over at a good speed and I can hear a very slight popping noise but will not fire, air in the system? Timing belt jumped? Any ideas please. I should add it's a 1.8 petrol.

Is the spanner light flashing ?, if it is then it's the immobiliser.
Probably flooded now so leave it a long while.

Make sure you lock and unlock the car before trying again, in case it is an immobiliser problem.

I had several similar problems with an Astra. Now whenever it fails to start properly I lock and unlock it again before trying to start it again. I haven't had the problem again.

No spanner flashing. Will try again in the morning and try locking and unlocking a few times. Cheers
Just had another thought about it, maybe a dodgy cam shaft sensor.
Had a cam shaft sensor fail on a Calibra 2.0 ( ecotec engine ) years ago.

Had wondered cam or crank sensor. Just seemed too much of a confidence that it was straight after it cut out on start up. Only cut out due to not havingEnough revs there to keep itself running.
benny, usually if it's the crank sensor it will start after a few turns of the key. I'd check the cam sensor first if I were you ( both not very expensive ).

I'll probably replace it regardless, I work in sales at a motor factor so will get the parts pretty cheap anyway. :-)
Way to go, benny. Good luck.

Cheers. Think I may need it in the morning when in taking the damn thing apart.
You'll be ok, benny, both straight forward jobs. When you change the cam sensor be careful not to pinch the cable from it in the cam belt cover when you put it back on.
benny, while you have the cam belt cover off to change the cam sensor have a look at the timing marks to make sure that the cam belt hasn't slipped a tooth or two.
The 2 camshaft markings align with each other at 3 and 9 o'clock, the crank mark points downward at about half past five and in line with the marking on the cover.
Blimey, you know your stuff, Tony.

Tnanks on behalf of the many on AB who benefit from your extensive knowledge.

Cheers.
