1999 Saturn SW2 stalls out after warming up and will not restart until cold again. Also very high RPM when running. Changed fuel filter but still same problem.Could this be the crank position sensor? If so where on engine is sensor located? I have looked and can not find it. Feeling stupid.

 

The crank position sensor won't normally be temperature sensitive, but the engine coolant temp sensor definitely would be. Try changing that first

 

10-4, a defective CTS would definitely cause hot start problems. Make sure the connector is clean.

 

replaced CPS today and it seems to have solved the problem.
