No Crank No Sync
Im finishing up a cab swap, 04 to 05.
Used all 05 harnesses except the engine harness.
Currently have a no-crank issue. It does crank with the yellow jumper wire, but won't fire.
Through my testing, I have no CKP, CMP Sync, and no FICM Sync.
After I tried the jumper wire it just didn't seem to be cranking right so I ran a buzz test.
Came back with 1,4,6,7. Which I know are all on the same connector.
FICM has good power Logic and Keypower was at 12V and the Main power was 49-48V
Would a bad FICM cause all these issues? Or even that 3rd connector having issues cause a lack of Sync?
From what i gathered through my research prior to my swap was id still be able to use my 04Engine wire harness, makes life easier as well, mostly so I don't have to move the EBP sensor or spend the money on an engine harness.
I also should note that I am using the 05 PCM that i got with the cab.
