I have a 1987 manual 4x4 2.9l singlecab reg bed ranger.
Things I have replaced: tfi, fuel filter, fuel pump, fuel tank, fuel pump high pressure, spark plugs, cap and rotor, plug wires, coil, map, cylinder heads, lifters, rockers, water pump, thermostat, temperature sensor, all battery wires and battery cables, ignition solenoid, ingnition key.
I had the truck idling after head replacement off and on for 3 weeks. And the day of registration it idled for 1h 45m straight than died. Now it will only run if fuel is added to the intake. What am I missing? Both pumps work and I'm getting fuel at the rail 40 psi.
