Re: 1989 ford f-150 supercab 5.0L
Top of my list is the coil, but get a Haynes manual (the older, the better) & a cheap digital multimeter, and follow the ignition diagnostic procedure, usually in Ch.5 Sec.5, p.5-5. How much fuel pressure does it have? Have you done a compression test since the rebuild? Spark plug gaps, wires, cap, rotor...?
