Thank u so much. It's installed now. Still no fire. Unplugged cam sensor. Inspected plug. It's clean. With volt meter I checked for power. 5 volts then I checked the ground at the plug. Still received 5 volts. As I was checking power I even shook the harness to see if maybe I had broken wire or short. Still constant 5 volts. Any ideas nkw as to why still no fire at spark plugs? Also I replaced both ignition coils, they are new. Only thing I can come up with is bad camshaft position sensor. What u think? Forgot to tell u. I scanned the truck and received a code. It was P0320 if this helps. I almost at end of my ropes.

P0320 is crankshaft sensor related. Either the wiring is faulty, or the sensor is bad. As they are known for failing you might try a replacement unit.

Testing for bias voltage is OK but you won't actually be able to see if either sensor is working because they don't use a constant voltage, they send a digital signal that can be seen with an oscilloscope, but not with a meter.

What was the ending result of the cause for no spark? Do we have a verdict.

We will need to pick the thread back up, can you tell us what you have tried? Have you check the fuses?

Vehicle information and what you have tried or tested as a start, pictures or videos of the problem are always good.
