1995 Saturn SL1 after car runs for 10-15 mins if you cut it off it will not restart for about 45mins to an hour. The Catallitic Converter has been removed Could this be the cause or what do I need to check. I tested the ignition module already it tested fine.

Sorry it has a 1.9L not a 2.2L It cranks but refuses to starts. I thought it might be the crank sensor, until I put it on a code reader today and it came up with "Coolant temp signal voltage low or short circuit"

What is the exact code number you have?Sound's like you have a bad coolant temp sensor or a bad wire or connector going to it.

The code reader I used doesn't give the P0000 format, it only gives what codes definitions. Could a coolant temp sensor cause the car to crank and not start?

Yes a coolant temp sensor code cause the car to crank and not start or bad wiring to it or a bad connector. The P then a four digit number is obd2 format your car is obd one so you would have a two digit number. If you flash the code's out it will give you number's.

The OBD I code was 15. I replaced The Manifold/Air Charge Temp Sensor. Seems to have fixed that problem. I just wanted to say thanks for the input SaturnTech9. My next fix will be the top motor mount.

No the sensor was in the manifold, near the temp gauge sensor. I was just saying what sensor it is. I'm guessing the one sensor has two possible since it was located as a air. Charge temp sensor and a manifold temp sensor.

The coolant temp sensor screw's into the cylinder head it's the bottom of the two sensor's right below the upper radiator hose. The one with two wire's going to it a yellow wire and a black wire. You are correct that same sensor is the same one in the air box and the transmission so it has three use's on your engine.
