2005 6.0 diesel shutting off while driving. Will crank but not start. Obd port dead as well.
Its happened 3 times now. Was going to let my mom use the truck bc her van transmission went out. Drove it to her house, turned it off, went inside, when we came back to start it, it would turn over but not "catch". The dashboard lights came on, everything electrical seemed to work. I went to plug in the obd scanner (some fancy touch screen snap on scanner or something like that my dad bought for hundreds) and it the scanner port didn't seem to be working. Tried using a smaller, cheaper scanner, same thing. Seemed like the port was dead. I leave bc i have work in the morning. Mom starts it up in the morning and it acts like nothing is wrong so she drives it to work. It shuts off on her halfway there, approximately 7-10 miles down the road. I pick her up, take her to work, get another truck and trailer with my grandpa, go to get it. It starts up again. This is an hour later. I drive it back to the house. Shuts off on me again after about 5-7 miles. Same thing. Will crank, not start. Dashboard lights and everything works. I have researched and seen that maybe the ficm could be bad amongst a million other things. I'm hoping that someone else has had this exact same issue bc I'm getting conflicting results on Google and I don't want to tear this thing apart if its something as simple as a fuse module
