Any progress, Lvoihotffer? I’m curious to see how you’re coming along. I’ve been struggling with a ‘93 7.4L swap for months now. The injectors not firing ended up being the distributor in my case. Probably the magnet because I had already replaced ICM, ECM, dist. pick up coil, cap rotor wires, IAC and pretty much everything else I could think of. When I replaced the ECM I went with the 7747 so I could hook up the knock sensor.
