97 SC2 needs full throttle to start

I have a 97 Saturn SC2. After running the car, if you shut it off and try to start it again within 10 minutes, it will not start unless I floor the gas pedal? It starts fine if its cold. Also, the temp gauge is always pointing to halfway. Is this due to a sensor? Are these two problems related and what can I do to solve both?

Sounds like the coolant temperature sensor needs to be replaced. This is a

5 minute job and a $10 part at any auto parts store.

The centered needle is an error indicator from the engine control computer that indicates that the thermal sensor circuit is open, indicates temp 150ºC. The two most common causes of this are a defective sensor, about $15, or defective connector for the sensor, $30, and only available from Saturn. If you have an ohm meter you can check the sensor while it is still in the head. You have to good eyes, and a steady hand to get the probes on the two tiny pins. It should read somewhere in the 3000-6000 ohm range at

70ºF.

I don't know if it is related to the sensor, but can't think of how it could be.
