I have a 06 Mustang 4.0 and I recently installed a supercharger and swapped out the fuel injectors. After doing all this the ECU will not deliver fuel to my number 6 cylinder. The reason I say it is my ECU is because I have tested the coil pack, plugs, plug wires, switched injectors and even tested the wiring for the injector and they are all good. So it has to lead back to the ECU. Any thoughts or solutions would be greatly appreciated.
