I have a 1993 Saturn SC2. It starts and runs and when it reachs operating temp it shuts off. After it cools it will do the same. I replaced the lower 2 wire Temp Sensor but it did not solve the problem. It has no error codes. Any thoughts?

When it gets hot and dies check and see if you have spark lets start there. Let me know what you find.

After it dies it still has a good hot fire across coil terminals just won't start. It does turn over with the starter.

Alright then you need to check to see what the fuel pressure is when it won't start.
