    Im going to try after work to see if the volts are getting cut or dropping somewhere when cranking.
    It's best you have someone turn the ignition while you test because you need to see the spark.

    You said you checked your fuse link. Can you take a pic of it and post it?

    Distributor cap? Are you getting spark form the spark plug?

    Pull out one of the spark plug wires, plug in an extra spark plug that you might have laying around, while you have someone start the car take the spark plug wire with the extra spark plug connected to it and touch the valve cover for spark. If there's no spark then it's the distributor cap and/or rotor because, you are getting power at the coil.

    To test from the coil to the distributor cap:
    Pull the lead wire from the coil to the distributor cap, put a screwdriver (with a rubber handle and wear rubber gloves) in the wire, while you have someone starting the car touch any metal on the car with the screw driver. Make sure your body doesn't touch any of the metal on the car. If you get spark, the coil is fine.

    Let me know how you turn out. I'm curious as to why you can't get her started. I have the same problem too and I think it's my distributor cap.

    Also, if I turn the key to on and ground the coil to the strut tower the wire I am grounding it with sparks.

    What about it? It registers sending signals out. Alot of wiring has changed in the car so could be anything.

    started a topic No spark, coil has power.

    No spark, coil has power.

    Im at wits end right now. I've read every thread and I just don't know what it could be.

    1985 325e Car with 2.7i stroker turbo. Whodwho Mega-squirt.

    -Coil has ~15v to + and grounded to strut with multimeter
    -Main relay seems ok.
    -CPS is brand new and spaced to 1mm
    -C104 Green/red wire directly to + on coil
    -Megasquirt reads sending out signals to coil
    -Tried another known working coil/relays
    -Fuel works, I can smell it.
    -C101 is rewired but seems correct
    -Unplugged OBC and tried still nothing
    -Fuseable link is okay

    Any other ideas? Need someone to talk it out with. Maybe run more checks?
Working...
