Have 1990 mustang, still has factory distributor, and all the fuel injector wiring harness, and computer. Question is whenever i hook the computer up in the kick panel of floor board, the car dies. Why does this happen?? Any suggestions.? I have researched that it kills the power to my coil. Unplug the computer and the power comes back on to the coil.? Will this happen if i hook the fuel injection back up? Or will the power automatically come back to the coil when i hook up the fuel injection? P.S. i purchased the car this way, i want to put the fuel injection back on it. Any help will be appreciated. Thank you very much.
