So I upgraded the camshaft in my engine and my tuner couldn’t work his magic on my 03 PCM, so I swapped it to an 05. because the engine started, I have good reason to believe that my wiring was on point. Took it back to the tuner and it was throwing a P0340 code - unable to find the camshaft code. I checked for voltage, replaced the CPS, inspected the Crank sensor, and saw higher voltage readings once or twice from the crank sensor.
I think the issue lies with either the PCM or harnesses because the PCM was a used one off ebay, and at one point when the truck wasn’t starting, I wiggled the harnesses, the truck would run again. Seems to be the most suspicious to me.
I’m running a 2003 5.7L hemi with an engine swap currently.
Any wisdom from the forum gurus would be greatly appreciated.
