The 1987-1991 F150 pickups were some of the toughest trucks, and they were some of the ugliest made. But the ugliness grows on you after a while. They have thick metal body and no front crumple zones on the front of the frame.
The only reason I’m doing a ignition and fuel injection do over is the truck is the truck sat for over six years with full tanks of fuel. The fuel looked like chocolate pudding with chocolate chips. The electrical system was damaged by mice living under the hood. The whole wiring harness from the ECU to forward was destroyed. The ECU is bad. 4 out of the 6 injectors can’t be rebuilt, EGR bad............
Fortunately, the engine is in excellent shape. Compression is well within spec. Within a 5% difference from lowest to highest. Since I got the truck for free and emissions is not a concern l’m going to convert it to a simpler setup so maintenance will be easier. At least that is what I’m hoping for.
