Hello everyone.
I have a '94 OHV with EGR that I'm trying to get running. It fuels fine but I have no spark. At the EDIS box I have; power, ground, a good crank position signal verified by scope, and continuity to the coils. Manually grounding a coil causes the engine to burp. There is no signal to the tach (I don't know if thats normal at cranking speed, it is also an '89 gauge cluster that had a distributor so it may not work at all now) and the EDIS makes no attempt to ground the coil. I have tried this with and without the jumper to the ECU installed. I thought the EDIS was bad. I installed a new one from the dealer and it has not solved/changed my issue.
I'm running out of patience and favorable weather. Anyone who can chime in with experience will be appreciated.
