I guess no one has had this question before, ok here is what I found so far after a year, the two J3 red wires should have 12 volts at key on, guess what one has nothing and I did the wire trace and it's good, so I am guessing that I have a bad relay \? any help is appreciated Ethan Rolling Eyes

they are both 12v feed fed from the same wire that feeds the orcv which in turn is fed from the ecm relay2

Hi Ethan, so where should I measure 5 volts on said sensors?
I have everything else working except I can't find 5 volts reading on the CMS or CKS.
Thanks

i think that is a typo as some sensors are 5v on the engine like the temp sensors but according to the wiring diagram the cam and crank are fed from a 12v feed which doesn't come from the ecu so if you got 12v at the sensors then they are getting a feed so then check for an earth and then when cranking you will need an oscilloscope to check the signal is ok
