B4000 starts sometimes, other times no spark
My B4000 has this funky habit of not starting at times. For a while I thought it was when it was hot but now it happens whenever it wants. After some troubleshooting, I have found that when it doesnt start, I dont have any spark. I am leaning towards the coil pack but wanted to see what others have found.
Either the coils, computer, wiring, or crank sensor.
Maybe ignition modulator
