I have been working on a 89 5.0 the car has a lot of work done.. The car lost power to the fuel pump, also isnt getting a injector pulse, and also isnt getting any spark off the coil until after I am releasing the key. I am really confused. The car has went through 2 brand new distributors and mods also has a brand new coil. I was thinking about replacing the fuel relay under the driver seat? also i checked the fuel cut off switch behind in the back.
