DISTRIBUTOR On electronic ignition there is a two wire rubber connector that connects the dist magnetic pickup to the harness (and to the electronics) Maybe you bumped that loose. Find it pull it loose, examine with light for corrosion, and work in/out several times to "scrub" the terminals clean. There is only a tiny current through there, so a bit of corrosion will cause that connection to fail.
DO YOU HAVE a test light, a multimeter, and some alligator clamp jumper wires?
DO YOU HAVE a factory shop manual? If not you need to get one
Also go to mymopar and download the aftermarket wiring diagrams, while these are easier to follow they are not fully detailed
