First thing I did was pull the camshaft sensor it was difficult came out in pieces took a long time finally got it out then I get other codes lots of them I did discover a three wires on the bottom of the camshafts sensor lines that were definitely connected melted together I fix I fix them then I'm getting more codes so I ended up like 11 or 12 codes all together still chasing it down found a few more shorts and wiring replace that soldered a new wires in the truck when it starts it goes to a very high RPM and then dies replace the mass air flow controller place the map sensor replace the crankshaft sensor I must have another short somewhere where the computer is fried as I trace out the wiring harnesses and fix the shorts I find I will continue to accept any opinions or suggestions junkyard might be one to take it to now it's going to get parts on it I just got to get to the bottom of it I'm sure it's a wiring issue I checked the fuses they were good one was was bad but it was I replaced it and it's the same no change that was on the ignition side I need to check the relays a little better make sure I'm not missing a leg or anything I got a few it's been a good truck 308,000 was running good until it didn't also the leaks a lot of oil I think I'm going to get to the bottom of that too probably going to go ahead and drop the pan cuz of the shavings from the camshaft sensor I know there is some in there and some came out when I drain the oil I plan on running a bit through there but how many and pull it for that dango o-ring that goes week on that pick up tube. I fix alot of things and i like a good challenge just notin my ride.Lol still feelin blessed these are fixable problems my fav kind. Need a good ignition wiring diagram. I got a basic obd 2 amd a fixed scanner both are good. Tuming us off and air fuel mix put on new coil pac wire and plug on cylynder 6 havent gotpo106 since. What am i missing ignition fuse ok tracing individual lines for shorts any spots where that is common?

How are the ground and hot cables? Were you able to peel back some of the coating to make sure it’s not corroded where you can’t see it?
