(excuse the long post) Hey y’all I’m new to the forum and had a problem that no mechanic has been able to figure out yet. I just picked up a 1988 F-150 5.0L/ 302 (Non-HO) 4x4 5spd with around 220k miles on it a few months back. Truck ran like a charm for weeks with no problems except an oil leak and missing window. I found the oil leak coming from the O-ring on the distributor, and decided to replace it. Took out the distributor, marked the timing, and reinstalled with the new O-ring. Crank, but no start. I had a few extra bucks lying around and I went to preventative maintenance and decided maybe the distributor died on me. So put on a new one. Still no luck. Here’s what’s been done since:
Found TDC and did the normal procedure to set the ignition timing about 11 times now with no luck.
New motorcraft spark plugs
New Accel spark plug wires
New starter and solenoid
For those going to ask, heres what I’ve done/ found. Spark plugs are all getting great spark, checked them all twice. SPOUT connector is out. Fuel pump and relay click with key on, and fuel rail is keeping a consistent 44psi for a few mins after key is off. Inertia switch is not active. Fuel injectors are working, and even tried starter fluid with no luck. Compression is good. Air intake is good. Mechanical timing is good. Distributor turns when cranking. Have tried all the above with old and new distributor. Checked the ignition switch, grounds, and all the wires from the ECU and solenoid with all getting proper resistance/ voltage. Battery is getting proper voltage and amperage. Fuel is new, as just filled up before it wouldn’t start. Only been sitting for about 2 weeks.
Again, please excuse the long post, I am just super stumped here. Between me, my buddies, and mechanics, I’ve had 15 eyes on it with no luck. Any and all help is greatly appreciated.
