I also noticed the 10A PCM fuse had no voltage to it… I don’t mean it was blown but neither side of the fuse was getting power. None of the fuses looked blown but I checked with a multi meter there were a few towing fuses that didn't have voltage to them but I had nothing plugged into the tow connectors so nbd. So I pulled all the fuses and cleaned with compressed air and they are seated nice and firm. Truck is a 2013 with about 70K miles and 2220 total engine hours. The fuel pump communication code came up twice.not sure if that matters.Īnyone have any ideas? I hate going to the dealer because they know they have your balls in a vise especially if it is a computer issue. U0140 - LOST COMMUNICATION WITH BODY CONTROL MODULE P062A - FUEL PUMP "A" CONTROL CIRCUIT RANGE/PERFORMANCE U0109 - LOST COMMUNICATION WITH FUEL PUMP CONTROL MODULE So i drive to AutoZone to get the code and I get the following: So i turn the truck off then on again and it starts running normal again except I have a check engine light. So i coast to the side of the road shift into park and it wont let me shift out of park. The screen said "shift to park to start". It seemed like I was shifted into neutral, the engine was still running at idle but hitting the gas pedal did nothing.
Now, I was driving home from work yesterday truck is driving perfect then suddenly it was as if the engine/transmission/throttle were all disconnected from each other. Member "Zlow28" suggested the fuel pump was going bad and he may be right but I now think its a computer issue relating to the fuel pump.
Okay so I have another thread on here titled "Truck Sluggish to Fire Up" and I detailed that my truck was cranking fine and has new OEM spark plugs but was stumbling/hesitating before finally starting.
