If there are any trouble codes in the Power-train control module we can use those to move forward and narrow down the diagnostic procedure to take. Also verify the sound that the engine makes when you turn the engine over while holding down the accelerator pedal all the way down, should have a uniform sound. If there is a flare up sound as the engine turns, there is an issue with low compression from one or more cylinders. Should be like nee-nee-nee-nee-nee-nee, not nee-nee-neeer-nee-nee-nee (stop laughing) lol, anyhow if compression sounds uniform then possible engine overheat, if not that then we go back to retrieving the codes because we might be chasing an electrical or ground issue. Let us know where you are at with the truck and I’ll be happy to get you there!
