It is a high-current generator. The engine's computer sends a signal to the coil so that it can boost the energy that will be conducted through some special wires to the spark plugs and, in one of its ends, the spark that will later spark the fuel mixture inside of the cylinders will be generated.
It will work good but start blowing hot air but the whole coil under the hood stays cold the top part and the bottom and the parts that runs to the air condition coil it don't need any freon and the fan works
My truck backfired and died while in motion, it restarted after a minute but i drive another mile and stopped and turned it off and now it will not start. It turns over strong, had fuel coming thru the fuel rail, i just replaced the ignition control module, the ignition coil, the distributer cap, the rotor, and the cam shaft position sensor after this happened a week ago and a week before that as well.
When i add fuel in the carb manually it still won't even fire. What could be the problem?
