If you were a registered user, you would not be seeing this!

2 days ago, the temp was about 0F. We tried to start our 2002 Neon and it would occassionally fire, but never start. I ran the battery down quickly, but jumped it and kept trying at variuos times as it warmed up to no avail.

Near the end of December, my son's 1995 Intrepid had done the EXACT SAME THING! I just replaced the crank sensor ( Goodbye 50 bucks!) and it did not help. I have no diagnostic tools, just part swapping ones, so please don't ask me what the shape of the signal was on an oscilliscope! ;)

What would these 2 cars do the same thing at around Zero dgrees?

The valves open and close, and after a bit of cranking the smell of gas shows that fuels must be present.

Any ideas?

Please help soon.

I had to borrow a CHEVY until one of these is fixed!!

I do have a digital volt/amp/ohm meter if that would help anything.

Change the spark plugs. Plugs with worn electrodes increase the power needed to fire them at very low temps.
I had the same situation several years ago when we had a two week period where -10F was considered warm. Thought it was the battery, but a new one did no better. Changed the plugs and everything was fine.

Even with no diagnostic tools you can pull the codes, at least on the Intrepid, maybe the Neon

I'd also VERY CAREFULLY try a shot of starter fluid down the throttle body. if it starts and stall it is fuel related. It still could be even if you smell gas.

Then next I'd pull a plug and check for spark.

Believe it or not, your plug wires can cause this. If they're old and have a lot of miles on them, you need to replace them. The resistance is probably no good anymore. I've seen this happen on numerous cars over the years. Old plug wires and cold weather don't go together. I have no idea how I hit this topic from back in February. I'm going to guess it's been solved by now. LOL

Hey Bill R, did you notice that his post was from February of this year? I didn't until after I had replied. I doubt that he will be back for suggestions. LMAO
