After cleaning and checking all of the connections I put dielectric grease on the connectors. I have run continuity checks to the pins at the ECM for each wire in the circuit. I have a 5 volt signal where I should have it. I have checked the ground wires and all are ok. What am I missing?
I put in a new timing chain and guides. Timing is exact, new spark plugs and new OEM cam and crank sensors. New ECM that is programed to my Vin. Now truck will crank but not start without any codes being generated.
Guessing you used a meter to test continuity. I'd double check the wires with a test lamp to make sure the wire is capable of pushing current,. If the wire seems good with that higher current test, next would be to probe the wire with a scope to see the signals when operating. That involves pretty expensive equipment, and a mechanic that knows how to use it.
Starting to look like you are getting too much gas. If you have a scanner, see what temp the PCM thinks the engine is. Pull a couple plugs, are they wet?
