97 Jeep Wrangler w/ junk yard motor installed, has had multiple cyl. misfire. New cap, rotor, plugs even sprayed the area with water with no change. Found what I thought was a bad crank sensor (hit when they installed motor).
New aftermarket sensor started truck ran 4 miles shut off-no start or fire the next day. Sensor tests bad (OHMS) again! Should I be checking motor and computer #'s to see if they are compatable? Thanks for any information.
