New member here. Strange PCM/electrical problems??? Please help.
2004 Durango. I purchased new. No modifications, all stock. 170,000 miles. New battery and alternator.

Recent problems - Engine stalled for no reason, Would not restart. Started after approx. 20 min. AC compressor would not run, next day, AC works fine. Security system will not function (key remote), next day, works fine. Engine runs for several seconds after key is removed, next day shuts off fine. Radio randomly came on while vehicle was parked. All dash lights come on intermittently. Engine codes - U0101, U110c, U1120, U1411, U110c.

This is my primary vehicle and I need it to be dependable. Does anyone have any ideas?

Thanks, Rick

 

Start by checking all the battery connections and grounds.

Great idea, thanks. I have checked all connections on top (battery, alt, plug ins...). Any idea where ground straps are located on a 5.7?
Thanks again for reply😎

 

Have you tried to "wiggle" the key? Forward /back and Up/down ? Might be the key or ignition switch going bad.
