The CPS wires feed up and into the ECU. He would have to purposefully move the wires in order to pinch, nick or cut them.

Since it is trying to start that is good. The crankshaft position sensor and the camshaft position sensor work in conjunction... I believe it is 8 crankshaft pulses(or more) between camshaft pulses for the car to start. The camshaft sensor is up on the FRONT of the block, on the passenger side by the valve cover.

I agree with the check the cables with a meter, from CPS conector to the ECU. Check the camshaft connector and make sure it is solid also. Maybe check it with a meter also.

You can also put a voltmeter across your battery and watch it while your trying to start the car. What does the voltage read? If it is below 11v it may not be turning hard/fast enough to get the 8 pulses on the CPS.
