    Help - cranking but not starting!

    Help please - what could cause this? After a faultless 180 miles (120 + 15 + 15 + 15 + 15) over two days, my ABY S2 failed to start in the morning for the return journey. Battery is fine - it cranks over but doesn't start - the fuel pump doesn't run and there's no spark/ignition. All thoughts welcome!

    The cam sensor can fail all of a sudden. Try pouring some hot water down the front of engine between the cambelt cover and cam cover. Sometimes that can work

      Thanks Sal. Hot and cold have made no difference, but blink codes say 2113 - G40 camshaft position sensor - so looks like the right place (and wiring) to be looking.

        Doesn't cam sensor always show a fail when the engine isn't running?
        My bet would be on an ECU fuse failure

          Its the crank sensor that shows a fault when not running

            It lives! Replaced the camshaft position sensor and it then started first turn of the key.
