I have read several threads in the past, but now, it's not helping ... I have a 97 SL1 sohc .. A few days ago, we had bitter cold temps for this area, my service engine light stayed on for about a day and a half, then went out. The car didn't seem to be running any different. Two days later, I was driving on the highway, the temperature gauge shot down to below C .. then when changing gears, the idle would zoom up 5-8 hundred rpms. I went looking thru the threads, changed out the temperature sensor, but its not making a difference, and now, on top of it, it is not wanting to start, almost like its not getting any fuel, but i know it is, as its used an ungodly amount of fuel in the last day plus ... please help..any suggestions would be greatly appreciated !!!

engine coolant temp
Could be an idle air control valve.Try starting it with the gas pedal pressed down slightly. If it works the IAC might need cleaned.
Also try pushing the gas pedal to the floor . It might be flooded. This will tell the pcm to shut the injectors off.
How many miles? New plugs.

I've tried several times with different pressure on the gas pedal, I thought at first it might be flooding, but its not, I don't smell gas when I do .... after the temp sensor was changed, I did pull the battery cable in hopes to reset the internal computer, ha, thats what i get for thinking i would get off easy !!

Could be fuel pressure or clogged filter. I do believe your year saturn has a combined filter/pressure regulator. I would still swap out the plugs first.

I shall do that, thank You so much .. but I'm still thinking its something connected with the coolant temp because of the way it does ...

Where did you get the temp sensor. OEMs are best with the updated brass tip. Not real keen on wells brand electrical stuff.

yeah theres the problem auto zone.
see its either your spark plugs are bad, but you have had those longer then this problem so you what kind of gas mileage it use to get with them, exhaust system is bad, doubt that, air filte clogged, not going to cause no start, or its the coolant temperature sensor. sure theres more but didnt want to write more. ok but anyways, if the sensor wasnt bought from the dealer, you got junk. go to the dealer and buy the sensor and the pigtail connector. this will ensure that everything is fine there. this is the biggest problem with a saturn, and when it goes bad its almost always starts out with dropping gas mileage badly. its the only thing too that would cause your temperature gauge to just drop, unless gauge is bad.
