A failed crankshaft position sensor can cause symptoms like this. When you crank the engine, the engine control unit looks for a signal from the crankshaft position sensor to determine where each cylinder is. When the signal is received, the engine control unit will power up the ignition system and the fuel pump. If no signal is read either due to a failed crankshaft sensor or possibly a faulty engine control unit, the engine will not start. A diagnosis as to why the vehicle will not start should be performed as other components such as the fuel pump can be at fault as well. Replace the crankshaft position sensor if it is determined to be the cause.
