Yesterday I noticed my truck cranked longer than usual before starting, but still started and seemed to run fine. Today, it cranks, but won't even attempt to fire up.
I did as much reading up on this as I could and the common issue seems to be the ECM relay or the IDPM. I did have the ECM relay recall taken care of several months back, but went ahead and tried the suggested ECM and fog light relay swap, which helped none. I used my BullyDog to read the DTC's and got code P0340 Camshaft Position Sensor A Circuit.
If I'm understanding the electrical routing correctly, and electrical circuits are far from my specialty, it could still be the IPDM that is keeping it from starting. Or it could be as simple as the code states and be the Cam. Pos. Sensor.
Has anyone had these symptoms, possibly along with this code? If so, did you figure out what fixed it? Is this more often than not the IDPM or the actual camshaft pos. sensor? If switching the ECM and fog light relay didn't fix it, would swapping the IPDM effectively be doing anything different?
I appreciate any input as I hate to just start throwing parts at it without at least trying to narrow it down to the most common issues first. Thanks in advance for any opinions, suggestions, or experience. Also, I apologize for putting this in multiple sections, wasn't sure where it would get the most eyes.
