I took the plastic cap off the coil and checked for power where the wires connect to. I thought my test light should be pulsating when i cranked the motor, but it just stayed on solid.
+12V on the coil positive terminal should be constant.
12V at the coil negative (green wire) should be pulsating.


Try disconnecting the coil negative green wire.
Run another grounding wire to the coil negative with the other end free (do not let it touch the ground).
Put a spark plug on the coil plug wire distributor end and ground the plug to chassis or engine.
Turn ignition switch to ON. Test to make sure coil has +12V.
Touch the grounding wire free end to any grounding point.
Did you get spark?

If you did, your DME computer is not providing grounding pulse to the coil.
What is missing? Could be ref sensor or DME itself.

If you did not get spark, coil is bad.
