Our 93 cavalier with a 3.1 has lost oil pressure and there is a ticking in the engine. My wife told me the pressure guage had been dropping to 0 but would jump back up where it was supposed to be fair

Highly doubtful that a pump will fix a 0 oil pressure problem. This sounds more like worn bearings. Have a shop do a pressurized oil leakdown test before replacing the oil pump. If the bearings pass the test, then try a pump.

Oil pressure light comes on and valves rattle after warmup

Sounds like a failing engine.
Assuming the engine is full of oil, could be a weak oil pump or worn bearings.

Where do I locate my crank shaft sensor

The Crankshaft Position (CKP) sensor on a 2003 Chevrolet Cavalier equipped with a 2.2L 4-cylinder engine is located on the front of the engine just above the starter near the oil pressure sending unit.

03 cavalier starts then dies

Generally when this happens all the time the fuel pump relay has gone bad. Upon starting any GM car up the fuel pump operates off the third wire on the oil pressure switch. When the oil pressure reaches operating pressure which happens in a few seconds the computer shuts off the current from the oil pressure sending unit and opens the circiut flow to the fuel pump relay. The relay will run ythe fuel pump until you shut the engine off. Replace the fuel pump relay and you shall have a good running car again

2003 Chevy Cavalier not starting

When you turn the key, you should hear the fuel pump make a whiring noise as it dispenses the fuel. If there is no noise. the fuel pump is not working.

Have you checked the fuel shutoff inertia switch.?
Check your owners manual for location.
