so my van sat for 3 months without running, today i just replaced the lifters(pulled the rocker assembly all the way off) got it all back together and i don't have spark, i did a quick check over all the connections i could find... i couldn't find the main fuse box juts the one for the accessories?

any ideas or theories would be appreciated
thanks

EDIT: i'm getting 0-2 volts at the dizzy end of the coil wire

EDIT2: getting 12v on the coil output and on the two wires going into it but when cranking those 2 wire drop to a steady .7-.76

EDIT problem solved, the plug on the back of the dizzy was slightly ajar

Maybe the ignition module?It is in the distributor.Distributor from dodge ram 50 1990-1993(4g64),Mitsu mighty max or Hyundai Sonata 2.4 1989-1991(g4cs) fits.

i'll check it out tomorrow after cleaning all those cobwebs from the intake side of the engine bay, that's good to know as i have a 91 mighty max sitting out front with a blown waterpump i can borrow parts from to diagnose.

there should be 20kv coming out of the coil? so something is causing the coil to let power flow right through it without amplifying

If it's the 3.0L, there was a recall on the engine because the crankshaft pulley bolt would shear off. I had it happen on mine and it ruined the engine. Sorry for the side-track, but I figured you might want to know if you didn't already.
