For us to be able to assist you, it is absolutely necessary for you to include the make, model, year and mileage of your car. (And tranny)

Explain no kind of power to the coil. 12v or no spark out of the coil? And how do you know, have you tested it with a meter?

Power to your coil comes directly from your SBEC )single board engine controller). It could be an auto shut doen relay. Check the voltage on the dark blue wire of you alternator with the key on. Let me know

Sounds like the auto shut down relay isn't on. It is also turned on by the SBEC. Either it is bad or the SBEC. It is in the engine compartment and with a breather hose running to it. It also houses the voltage regulator and is a high failure item. Good luck

Are you talking about the auto shutdown relay or the sbec with the breather hose cause I checked the relay with a meter it is fine and my sbec only has wires going to it

The auto shut down relay is activated by the SBEC. If the relay was energized you would have power to your coil and alternator and 12v side of your fuel injectors.
