1998 saturn sation wagon car starts wont turn over

SOURCE: I have a Saturn L200.

I'm experiencing the same things with my '03 l200. My mechanic replaced the fuel pump about 3 times before finally telling me it was the body control module. It will cost me about $260. On top of the problems you mentioned, my car also doesn't register miles in the odometer, and the dashboard lights flicker. He said all this was because of the faulty body control module.

Try pulling the engine coolant temp sensor, They often crack not sure why but the ceramic tip cracks makes the car hard to start, the car's idle may race while shifting gears, and often smokes. The sensor is on the right side of the engine when looking at it on the head. Easy to change and get too

SOURCE: 95 saturn won't start when hot

Blair, I would take a look at he TPS (throttle position sensor) located on the throttle body. In other words, it sounds as thought sensor when heated is changing its value to "open" or "shorted".
If the car starts OK when cold, use a hair dryer to heat the TPS when the engine is cold to see if you can duplicate the problem.
Also is the a service engine light on? Codes?
If you have a "digital volt/ohm meter" available you can read the variable resistance of the sensor when the problem occurrs to determine if the sensor is defective.

SOURCE: how to replace coolant heat sensor on 1998 saturn

the coolant temp sensor is located on the right side of the cyl head its small under by the upper rad hose 13mm socket removes it after u take the small connector of,make sure the car is cold coolant will come out when u remove it,,,,check the connector too for corrosion,by only saturn sensor the cheap autozone and aftermarket ones dont read right and give you the same problem as the old bad one
