If temp goes below 15 degress outside car cranks but won't start - Engine cranks and sounds like its desieling - Sounds like air/fuel mixture not correct - Wants temp warms to 40, cranks,starts and sputs for a few seconds then ok - Once engine warms up , starts right up(fires within 1st second) Could engine be getting too much fuel and not enough vapor???

 

Well I can tell you what my probem was, It was -24 and my wifes car (96 3.3 intreped) started right up, the next day -36, it did not start, so sat. I changed the plugs and it started but would stall at a red light etc, got home disconnected the batt. cleared the codes, there wasnt any put cable back on went to start it and bang, what the h was that, and never started after that so I did soom research on the forum and came up with a crank senser, 60 dollors, I took the old one out and there was a glob of greese on the end of the senser, cleaned it off real good I decided to put old senser back in and try it, that car has never started that quick ever, let it warm up real good and took it for a ride, and ran like new yuo may want to check your crank senser, easy to get to, take it out and make sure the senser side is clean, I called o'Reilleys and they said yes that would have the problem as to why it wouldnt start or keep running, Hope this works. We plan on tradeing it in this week.

 

When checking codes get 12,51,21,55 . Can an O2 sensor cause a no start condition in temps under 15 degrees and starts fine when weather is warmer ??
