Maybe my terrible experience can help some unlucky soul in the future. Bought a 92 4x4 4l ranger off craigslist and the dude said he installed the battery backwards and his "mechanic" diagnosed it and it should fire right up with a new eec. Boy was he wrong, additional stuff fried by battery and several unrelated issues. Heres a parts total:
1) solenoid by battery. Symptom: No crank while bridging 12v to signal wire but crank when bridged starter input directly to battery.
2) alternator and fusible link. Symptom: not charging and no continuity down wire
3) icm. Symptom: no spark when Coil ohmed good, was recieving 12v, had new plugs for maintenance. That one was a shot in the dark but got lucky.
4) new electric key switch on steering column. Symptom: no koeo accessories getting power. No power to started signal wire to engage solenoid by battery. Confirmed all relays getting power prior to.this discovery. What a pain. The switch split in two and wasnt making contact.
5) new maf sensor. Symptom: checked on a whim due to poor performance and the wire was burned through about 80%
6) new fuel pump. Symptom: hard start, wouldn't take throttle, misfire, low power. Confirmed good spark and plugs dry. Hooked up gauge and had zero psi at rail and directly before fuel filter. Took pump out of tank and rubber hose from pump to hard line was dry rotted through dumping all my pressure.
Good luck, have fun
