I have a 95 Sunfire with the 2.2 liter engine. My problem is that when it gets below 20 degrees it will not start. Push it into the garage were its heated and after the car warms up it starts fine.

To date I have replaced the engine temp sensor. I've checked the plugs to see if they are firing and they are, however, I'm not seeing any fuel on them. Checked the fuel pump relay and its working fine. Put a meter at the disconnect under the back seat for the fuel pump and when you first turn the key on it gets 12 volts for a few seconds and then stops as if the system is pressurizing fine. Replaced the fuel filter.

This car is OBD 1 so my scanner won't work on it. Its not throwing any codes per say, since the Check Engine light doesn't stay on.

Any suggestions would be greatly appreciated.

My pontiac has the same problem! I did figure out my problem tho, kinda... I turn the key andlet thepump run 2 times before i try and start it, plus! I have to make sure when its cold out i have to keep my tank abouvehalf and use drygas through out winter.
This helped me out. before i figured that out my car was dead every other day and once fora week.
Hope that helps.

Well. You have an electrical problem somewhere...

i dont think that the fuel filter had anything to do with it. but yeah it deffinatly sounds like an elecrical problem. check your grounds and have your battery checked out. could be a problem with the wiring.
