I have a 1999 Dodge Cummins 24 valve. It's suddenly hard to start so I checked the codes. I got 380 & 382, so I checked the relays and it's not getting ignited/excited on the heater side when I turn the key on.The battery side of the relays are hot. I used a jumper wire and manually applied them, I can hear them click on. The diagnostics in the scanner say to do this to see if the relay is bad, if not then it just refers to the ECM. Is there an air intake sensor that can go bad? If so where is it and how do I diagnose it.Is there a way to positively diagnose an ecm?
