After driving for awhile or the car warms up the car runs fine until i shut it down and try to restart. I notice when the key is turned on i lose the gas and temp gauge,also the door locks and dome light don't work and sometimes the fuel pump will not work. the car turns over fine but will not stay running because of the fuel pump. After about 25 to 30 mins. when the car cools down everything goes back to normal.
SOURCE: losing coolant
Please check the radiator it may be leaking or there may be hole in the coolant container or the sensor is defective get it checked ..................................

I also had the same problem with my 1996 Saturn SL1, and it also was the starter. I thought it was an electrical problem until, just on a whim I pulled the starter. One of the brushes was almost gone and the commutator looked like hell. I cleaned up the commutator and brushes, and it spun like a top for about a month, until the worn out brush finally died. I also ordered a new starter the same day of the cleaning. Just a word of advice if you will be buying a new starter, go on Ebay Motors and find the store dbelectrical. They sell brand new starters for $49.95 with no core charge plus $12 UPS shipping. So $61.95 vs $150+ at your local parts store....Myself and my friend from work have both bought and daily use starters from them with no problems or complaints to report.
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: HELP!! Having electrical issues with my 2005 Pontiac
electical is hard to diagnose with out being there. i would treat each problem seperately. first you will need to test the engine temp gauge sending unit. in a dealership this is easy with a scanner they can run a sweep test to se if the gauges are responding.you don't want the engine to over heat if the gauge is not working. next problem the dome light should be easy to fixe does the dome light work with the dome switch?remove the bulb and with the doors open and switch on check for voltage, if voltage check connection and or replace bulb. if no voltage check fuses for voltage.last will need to have the dtc po243 checked out by a repair shop. i hope this will help.
