89 Chevy k1500 5.7
Truck would start run and drive no issue. I
got new spark plugs wires and a cap and
rotor. And now it no long starts. It cranks over
but will not start. When it’s cranking over it
will back fire but the truck won’t run. I’ve
went over my the firing order numerous
times. Got a different cap rotor and wires.
Still the same issue. I took the motor to top
dead center and made sure the number 1
wire was positioned right. I can’t figure it out.
