So you just went out to start your daily driver one day and this happened?
Or is it a rebuild? New build? Swap? Factory vehicle with a factory harness? Swap with a swap harness?
It's not the everyday problem. Check the grounds.
Might be the PCM.
What is the vehicle model and year?

It's a 91 c1500 with a 5.3 swap custom harness built off of lt1 swap.com I've checked grounds even switched them around to reassure tested with a volt meter .08 ohms on all coil grounds and .05 and under on every other ground im gonna try another pcm but im still lost
