any codes pop up? and cant tell if you said the cam sensor is good, but ill ask anyway. does the tach bounce when cranking? if it is and you have fuel pressure id say its the idm as well.

Truck wont run without CPS.
At all.
It might detect RPM's, but the sensor isn't reading the timing right, so its just showing RPM's, but its out of focus so, no fuel.
I hope that helps a bit.
Its really a finicky thing.

I'd be looking real good for a wire that is rubbed through if it were my truck.

Last month my truck died. The tach was moving so I thought maybe not the CPS. The snap-on however read no RPMs so the tach CAN bounce when cranking and the CPS be bad but it isn't common.
