Ok, so the other day I went to crank my truck with remote start. Well it didn't crank. so I unlock the doors hop in and try to start it. Nothing all the dashlights come on MIL light comes on and flashes... I disconnect the battery cables and even cross them to drain any residual voltage. It does not clear and still won't crank. I get my wife to bring my code reader(just an OBDII scanner and torque on my phone) it was a Powertrain pcm fault code. I should have wrote it down but I didn't. I cleared the code and the truck cranked right up. Turned around and drove it about 1000 miles towing the camper this weekend with no problems. Drove it to work yesterday and back home no issue. My wife went to run some errands this morning gets in the truck and outta no where truck won't crank. I grab my phone and check codes and it had a p040d code. I bought the truck used from a dealer and the previous owner had already deleted the egr and DPF. I could not clear the code so I pulled the battery cables again. Went and rechecked the codes and now that code is gone and I hve a P144E Powertrain code that will not clear. Truck will not crank and everything I see is online is pointing to the fact that maybe I don't have a tuner?? It did not have one when I got it but I did not think anything about it. Truck won't crank at all. :banghead: Any ideas.
