Thread: Power to coil

  1. Power to coil

    On my 1993 jeep I'm building a computer for it.
    I wondered if I can just run 12v power to coil from switch to power coil? Will that send spark to plugs

    Your year had an electronic ignition system. If you want to go old school you will need the full distributor. How Ignition Systems Work | Champion Tech Tips

    Power to coil

    The old old system. It was mechanical. You align the distributor to the crank and cam shaft. Then the cam gear spins the distributor internal shaft allowing rotor to spin and make momentary mechanical/electrical contact to the end of each spark plug wire….

    In the electronic system is in that link . Scroll down. There is an ecm tied to the distributor and the cam sensor is in the distributor.
