I replaced all of the injector pigtails the other night with some connectors that I pulled off some Dodge in the junkyard. These are actually the correct types of plugs, so they snap in to place and don’t need bailing wire to keep them attached. I was operating under the theory that the car was running on three cylinders because one of the injectors wasn’t getting power, however, I managed to prove that point wrong. As it turns out, #4 isn’t getting any spark. I can get spark using the #4 wire with the #4 plug when it’s connected to the #1 position on the coil, but I cannot get spark on anything connected to the #4 coil position. Next step is to test the coil.
