electrical ,coil
still no luck ,checked plugs to coils ,passenger side coil plug checked out fine
center hot, left and right sides sent pulse signals (grounded) driver side
center hot ,right sent pulse signals cranked,but left wire sent solid signal
when i disconnected the driver side coil truck started but ran rough,
"only running 4 cyl" but will not start if plugged in, CAN someone point in the right directions ?
I'm thinking it's the coil module. If the controller isn't up to snuff then you're gonna have these problems. If the plugs are good (swap the ones that are firing for the ones that aren't) and the coils are good two (same check) then I'd say module.
