Have you checked (or wired around) the fuel pump relay?

It sounds like this could be a common problem - usually this is caused by the crank sensor going out/bad. The sensor is mounted to the timing cover on the front of the engine.
The crankshaft sensor provides both engine speed and crankshaft position signals to the ECM. The sensor is a variable reluctance device, consisting of a bobbin coil with a magnetic core. The resistance of the coil is approximately 1.35 kilo ohms . The steel teeth on the crankshaft timing ring are used as a rotor. As the rotor teeth pass by the crankshaft sensor, pulses are generated.
The rotor has 60 tooth positions set at 6° intervals with three teeth missing. The gaps identify the TDC position of the 6 cylinders during one complete engine cycle (two crankshaft revolutions). The rotor thus provides both engine speed and crankshaft position information to the ECM. The missing pulses identify crankshaft position. Each tooth pulse after the missing pulse represents 6° of crankshaft rotation. Thus the frequency of the toothed pulses are a measure of engine speed.

check all ignition wires on solenoid make sure they are not grounding.causing a short. if they check out good. have starter solenoid and starter make they are not causing the short.
SOURCE: car wont start, acts like
Check the battery +12v power connection to the starter is in good order,
Check the ground connection between the battery negative and the engine/starter motor is robust and intact.
If no problem with above, replace the starter motor.

Located under passenger's dash panel on yellow connector block.
