my car will start when its cold and run but if you shut it off, it will not start when hot, for some reason its not getting fuel when its hot(put injector noids on to confirm) but if you let it set for an hour or so it will fire. well today i was driving and it shut down on its own but while doing so the dash tach was going crazy the car was idling rough and back firing. the dash tach was spiking from 2-10k but the engine wasnt actually reving that high. on a side not my avcr was still showing around 1400-2000 rpms which is what the engine was actually running. anyone had similar problems? crankshaft or camshaft sensor going out possibly?
