This motor is in my 81 starlet. The harness has been simplified to the most basic sensors and ran smoothly until this point. My buddy hooked the jump box up backward when trying to start it. In his defense I dont have the terminals color coded or labeled. Anyway I can unhook each injector and coil individually and they all change the running of the engine meaning none of them are dead. Is it more likely that the ecu is toast or the ignitor? I have no way to run OBD since the harness is simplified. any help would be great. Thanks
