    Z20LET cutting out

    Help please, any idea what could be wrong with my Astra Sri Turbo?

    It wouldnt start last night from warm but did later on from cold, so i thought it might be a warm starting problem but today it cut out when I was rolling up to a junction with the clutch in and again later on. I managed to bump start it fine.

    Also its not the battery or alternator becuase when you start it normally its really good, barely turns over at all, just springs to life!

    I found out about the pedal test and got the fault code, its the crank shaft sensor, replced one of these on my mk3 2.0 ecotec seems like a common sensor failure in the ecotecs

    afm will throw managment light when its so bad, but a dodgy crank sensor most of the time won't. try a crank sensor mate they are cheaper.

    Classic symptoms of a duff TDC sensor, whip it out and give it a clean

    Do a pedal test, my SRi T did exactly the same thing

    I replaced my Camshaft sensor and it cured the problem.

    my symptoms - car would start fine from cold, drive for abit then car would cut out, if I tried to restart the car it would turn over but not start as if their was no fuel. Once the car was cold again, say 10 - 15 minutes I would try start the car and it would start no problem, but once warm again it would cut out.

    (Edit) Error code I got from pedal test - P0335, Crankshaft sensor

    Yep those are exactly the same symptoms as mine, although my code was 0335 which is the crankshaft sensor hopefully that'll sort it

    Sorry Phil, I posted the wrong code above

    I did get 0335 - Crankshaft sensor

    The sensor is located down the front of the engine, one torx headed bolt holds it in place, bit fiddly to get too but an easy fix

    That's good to know it was the same sensor, hopefully it's the only one that's prone to failure
