    Do you have a tachometer reading when you crank the engine? (this tells you if the crankshaft sensor is working)

    If that's okay, have you checked the ECM fuse?

    If the fuse is good, put a test light on it while you crank the engine. If the light goes OUT when cranking, you probably have a bad ignition switch.
