I left the key in the on position and started talking to some friends that were over and next thing you know there was a little bit of smoke coming from one of the injectors and it was really hot, so is the ecm ruined now? I have 2 spare injectors, should i just change that one and try it? What a pain in the ass, it was running really good and then something as stupid as leaving the key in the on position causes more problems, i think my truck hates me. Has this ever happened to any body, i guess when the key is on it is putting voltage to the injectors, is this correct.
