96 7.3l f250 having some trouble

Hello all, new member to the forum and hoping someone can shed some light on a recent issue that my truck is having. Truck has always run like a top and never given me any issues till about a month ago. I was driving down the street at 50km/h and the truck just died. Check engine lite comes on, apc module says CERR and the relay fuse under the hood for the glow plugs is chattering to no end. Then just as soon as it happened the check engine like goes off, the wait to start comes back on for a few seconds goes out and everything is back to normal. Start the truck off and I'm away. Didn't happen again for a couple of weeks. Then one morning I went out to start up the truck and the same thing happened. While the CEL is on the truck will turn over like normal just no fire. This problem seems to be happening more and more and now I can't even make a trip uptown without it quitting. I have removed both batteries, check them and cleaned the terminals and then reinstalled them. Both were good at 12.44 volts. I checked the codes that were in the pcm and there were 3 P0603, p0478, and p0470. From what I have read non of these should be able to cause the problems I am having. I also replaced the fuse for the glow plug relay and the relay itself but neither did anything except bang up my knuckles Any ideas of where to start looking would be greatly appreciated. Thanks

Well replaced all the grounds on the truck still didn't help. Was looking thru some old receipts for the truck from the guy I bought it from and found that the truck was chipped! Tore the parking break off and there was the chip. Took it out and truck has run like a top since. Chip must have burnt out and was shorting things out.

Many times the chip connection needs to be re-cleaned and reinstalled and secured (duct tape). Cheers!
