Just replaced heads, crankshaft sensor & camshaft sensor as well as reset timing. My Auto Shutdown Relay (ASR) is now clicking & I have a no start. I call it being in shutdown mode (not sure if right term). The truck will not start & my code reader only shows error. I got 2 codes prior to shut down (P0320 & P0725) I was able to leave the battery unhooked for a few hours today & once hooked back up I was able to clear codes. Truck then cranked & ran fine, I cut it off & on a few times & then let it run for 20 min or so. Everything seemed fine so I cut it off & put the truck back together. Went to crank her back up & she went back into shutdown mode. Any advise on what I can do next will be greatly appreciated, I'm pretty much at the end of the road with my knowledge. Everything I read about ASR says to replace a different sensor, don't want to have to replace every sensor on the truck.

 

Apparently this is a problem NO ONE knows anything about!!! So I figured I put up the solution in case someone else runs into the same situation. I ended up paying $50 to tow it to the Dodge Dealership, the said they hooked it up to the diagnostic machine & that my truck wouldn't communicate with their computer. I told them everything I had done & the codes I had pulled before it went into shutdown. They called me about 4 hrs later & said they had fixed it & the truck was running fine. They said that all the ground wires were tight except one was a little bit loose & it was the ground for the PCM (located under the air box,which I never took off). They also disconected all my grounds, cleaned & reconnected them. Said they were not sure if it was the loose ground or the grounds were just dirty enough to not get a good connection. So 3 hrs of labor charges I finaly have my truck back & running. So hopefully this will help anyone who runs into the same problem & save you $320!!

 

appreciated the answer and sorry no one could help you...same thing happened to be in my old jeep kinda checked everything was so stumped as to why it would only stay runnin with your foot on the gas and all it was was a bad ground somewhere
