Question about 1985 Ford F150
It will start if i bypass the fuel relay, but that is the third brand new fuel relay that ive put on it, and still no fix yet. am i gonna have to rewire this truck?
You need to check the fuel pump cutoff switch (located in kick panel), see if the wires to the switch are burned and melted, if they are buy a repair connector from Ford and replace the switch. Also the ignition starter switches in this truck have a habit of coming apart and causing a loss of power to the fuel pump or the ignition system. The switch is operated by a long rod from the ignition lock cylinder and it mounted to the steering column tube down near the bottom of column

get a code reader like the Actron CP9015 Code Scanner, 20 dollars and will flash codes. if it will not diagnose itself, the ecm must be replaced. this fixed my dads truck with the same problem

Replace the distributor's magnetic pickup located inside the distributor surrounding the distributor shaft, the only other thing thankfully on this ignition system if memory serves me on the f 150 straight six 300 cu inch is the dura spark ignition control box, of course do the obvious tune up parts replacement dist.cap rotor,plug , sparkplugs before spending the $40.00 - $50.00 bucks on the dist.. pick up, you may have a weak a fuel pump check for adequate fuel pressure at carb 7 - 10 lbs.
