Yousay that the engine won't turn over but cranks. I'm confused. Do you mean to say that the engine turns over but will not start?

throttle position sensor

or any other sensors.

disconnect the battery for 15 minutes

reconnect. then try to start. if its a sensor or computor malfuction that should reset it temporarily.
