A while back my truck started acting up. It was throwing codes 18, 36, & 78. After fiddling around with it, it gave me code 12. (All clear, right?)

I hauled to a show, truck acted fine there and back. Parked it. 3 days later, I went to move the horse trailer and the SES light came on. Checked codes. It gave me 34, 49, 57, 62, & 78.

I ordered a pdm and #5 resistor, just in case that was the issue.

Now truck wont crank. I tried swapping back to other pmd, cranked for about 10 seconds and died. Did that 2 more times before it refused to crank.

I am getting fuel to the filter. Pmd is on extension, mounted in bumper. Turbo wastegate arm does(did) not move while running. All grounds and connections seem to be okay.

Im having a hard time with tracking down how to go through these codes. The only one I can really understand is the one that suggests that my MAP sensor may be bad.

I am not a mechanic, but I can *usually* figure things out. Is there any one thing that can go bad that causes all of these codes?

34- Inj timing stepper motor fault
49- service throttle soon lamp circuit fault
57- PCM 5 volt shorted
62- Turbo boost sensor circuit low
78- Turbo wastegate solenoid fault

Thank you for any and all info/advice you can provide.
