Question about 1990 Ford F150
Basics-compression, electrical (battery, alternator), ignition (plugs, plug wires, ignition module, dist cap and rotor), fuel (fuel pump, filter, injectors, throttle body, regulator), management (engine computer)-petty much in that order.
An intermittant problem is usually electrical (primary or secondary ignition) so a voltmeter that measures resistance/continuity is a valuable tool. New and known-quality parts are better than cheap, Chinese knock-offs that might be junk out of the box but you are ignoring them becasue they are 'new'. Another good investment is a good OBDI scanner to see if you have a code since you have a EEC IV system which has particular weak points (like the pick up module). Grounds are also points of inspection and have to have good cables and immaculate contact surfaces free of rust.
