94 fd wont start. Running a lt10s not xbox to stock coils. I am unable to physically see a spark. Plugged up a spark plug to leading 2 and grounded the side. Set the laptop software to 0 cylinders. I can hear the injectors clicking but No spark. Tried it again with the other 3 wires, same thing no spark. First tested wires grey/red, grey/blue, grey/white, grey/green and saw that they are all grounded at key on and pulses ground when set to 0 cylinders. Is that right? Is that what its supposed to happen?

Are you wired straight from ecu to the coils... or running through the igniter before the coils?

Running through igniter before coils

Based on getting the ground pulses from the ecu coils wires when set to 0 you should be seeing spark. So at least you know your ecu side should be fine. That leads to me think its something on the wiring side of the coil/igntier.
Is the igniter still powered?
How did you tap/tie into the ignited harness with the ecu wires?
Did you check if you coils are getting power when the key is switched on?

Thank you. Ive been putting off checking the harness wires, turns out i had a disconnect at the harness.
