Hey guys, I have exhausted all options at this point at diagnosing my truck.... I recently replaced the cam phasers (2005 5.4l 3V) and the truck will not start, it will just crank. I've been able to narrow it down to not having spark, and the PCM is not giving ground. I have replaced the crankshaft position sensor and I have fuel pressure so i'm not sure where to look next. The intertia switch as well as all fuses are fine. Thanks for any help!

 

Are you missing a ground, engine to chassis. Maybe bad connection to crankshaft sensor or cam sensor??

 

Did you replace cam phasers and the truck ran fine for a period of time and is now not running? Or has it not run at all since you replaced the phasers?

 

I don't believe I am. would you happen to know where the engine to chassis ground location is? I have been unable to find a location on it

 

It has not started up since replacing them
