Fuel pressure at the rail is in the right range and the injectors were just cleaned and flowed fine. However the 6 and 8 plugs were carbon fouled when pulled out. I don't know what else to test for in the fuel system. The harness is the modified 5.7 harness. Noid lights showed all 8 injectors were being pulsed and I have 12 volts on the pink wires to the injectors, along with .3 to .5 ohms on the ground wires to the computer. I even swapped in a wire directly to the computer to control the injectors with no change. The coil wiring was pulled from the harness that came with the engine. I hooked it up like lextech described in the wiring file.

One thing to note, when I turned off cylinders 4 or 7 with efi live, the truck seemed to smooth out. When I turned off any other cylinder, the truck got worse.
