Have 96 Dodge Caravan 3.8L with no spark, Replaced Cam position sensor, Crank position sensor, still noyhing. It will turn over just fine, went to store at night, came out next morning and nothing, just turn over no fire. Is there anything in the ignition that would prevent spark? Because I have to wiggle key to get past ACC, also I tried unlock ing doors with the remote and almost sounds like I get hope of turning over? Dont think its the alarm. I read on line of the horn going off and lights flash, I dont have that, and I noticed the radio dosent work? Never worked very good to begin. Had to push buttons really hard. Could there be bad ground to pcm? I live in hawaii and we get alot of corrosion and rust?

Any applicable mil codes? Check primary voltage at coil, engine cranking, the dark green wire with orange tracer should be hot. That voltage cones from the asd relay, that relay serves several circuits. You can check the relay and relay circuits. The pcm may not be grounding the relay for some reason? One of the circuits that the relay serves, could be causing an issue.

If you have good primary voltage and a ground pulse at the coil with no spark anywhere, suspect the coil.
