I tried arching the coil wire to ground while cranking but no spark. I tried using a volt meter measuring DC voltage at the coil wire while starting. I saw 12V with KEY on then it dropped to 11.4 while cranking. I'm not sure if the coil is bad or the computer is not allowing fire due to a bad sensor some where. Does any one know what the red push button is on the side of the mounting plate that has all the EMISSIONS control garbage on it? I see and feel a red push button down there. I'll look to see if it is in the owners manual. I need to find a better way to trouble shoot the coil I guess. Its almost as if the kill switch is activated but its not.
