Have you checked the crankshaft position sensor, sometimes they can cause a false signal or intermitten signal to the ignition control module. It sounds like this is the culprit. Here is a diagram of the entire system and explains how exactly it works.
What it means by changing it into a camshaft signal is basically just stating that it switches the signal from ac voltage to a dc voltage like the camshaft sensor. It does not combine the signals. I would start with the crankshaft position sensor and have the injectors cleaned or replaced. If all of the components tested good from earlier than the only other possibilities are the crankshaft sensor and the injectors clogged up or leaking internally. I can send you test procedures for the crankshaft sensor if you would like.
The pulse to the injectors is fine because it gets its information from the camshaft position sensor. The information for the spark comes from the crankshaft sensor. I feel very confident that the crankshaft position sensor is problem.
Ok Jonathan I'm going to accept your answer becase it is probably right. But apparently I had a dumb blonde moment. My bad. A spark plug wire burnt pretty much in two pieces, and going straight to a very good ground. Apparently taking most of the coil's output.The one wire that appeared to be the only firing correctly. Replaced the plug wire and all is smooth running. Like I said it was my screw up. FYI a Snap-on Advantage does not show ckp sensor output on this model. Thank you for your time, and effort to help me. If or when I need help like this again, I'll be back for help. Thanks again.
