Hello, d150 5.2? I'd check the primary circuits at the coil for B+ and pulsing ground. If your TBI, can you see the injectors spray pattern? The circuits for the hall switch, orange--should be reference voltage, key on, gray is sensor signal, that circuit has a pulse, engine cranking. Black is ground.
