Re: Orson the 49 GMC ~ Chris C.
so my code reader given a PO336 code which says the crank position sensor must be diagnosed. We tried switching it out. There are only 3 wires. The lt blue has 12v key on, the yellow/blk has continuity with ground key on, and the reference Wire has ~5v key on. The adapters from EV6 to Delphi injectors got here yesterday, so we decided to rip out the modified one and install a pre-made with the adapters.
