ANY ONE HAVE / HAD THIS PROBLEM .My truck turns over but won't start. I scanned with a cheap tool and no communications , shows nothing. I scanned it with my better tool and have codes, U0100 loss com w/ECM PCM ,P1280 TCM cir#2 open ,C2202 vin mis match ,C2206 Configuration Mis match.Truck has 65,000 miles.I am a retired GM tech and with a GM product usually a ECM. Not sure on my Ram.Anything common I should look for as far as wires , fuse box , relays. THANKS

i had this problem about 6 month ago and it ended up being my barometric pressure sensor had shorted to ground. if this is your problem unplug the sensor and try to start the truck. mine started after I unplugged it. I have also been told that the boost pressure sensor or fan clutch will do the same thing.
