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 <-40ºC, or shorted, 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.

Some say we must tax corporations more. What they do not understand is that
corporations do not pay taxes. One of our governments conditions for their
existence is they collect the taxes from their customers and pass them to
the government.
