[99 GREEN D]

OK guys, my 99 Durango 5.1 has trouble starting in damp and cold weather. She fires right up if it is warm!

Any assistance appreciated.

have you had the battery checked? Alternator? you can run both into local parts store and have them bench check em. probably something real simple

IAT Sensor...???

I would check out the IAT (intake air temperature) sensor. If it not functioning properly at all outside air temps. it may have you running to lean when it is cold possibly causing your problem. Thinking O2 sensor may be culprit???
Hopefully you will get some additional input from others.

Best,

Do you have a service free battery or can you check the battery cell levels? But I'm almost certain it's battery.
