I'm having a weird problem with my Bronco 2. Same year as yours, but I'm having problems getting power to the fuel pumps. At first I thought the wiring was shot, but recently I decided to disconnect the connector that splits off to the two pumps and test the male connector, which when turning the key I got 12 to 13 volts going through it, hence why I thought the wiring after the connector was shot. Well I then decided to take a piece of wire and poke it into the female connector and touch the other end to the battery to see if the pumps would do anything, and to my surprise both pumps worked. Now I'm trying to figure out how a connector that has power, doesn't power the pumps, but sticking a bypass into the same connector does. Though another thing to note, is that I briefly ran it with the bypass, and tested the male connector while it was running to see if voltage was still being supplied, and I was getting reading of up to 20 volts.
My guess is that you're probably reading "ghost" voltage on the male connector. Hook up a 5 amp test light to that male connector and see if it lights. I bet it won't. It's probably a wire upstream of the connector that's cut and only has 1 or 2 strands left intact or a partially blown fuse or partially failed relay. If you already figured it out, let us know what fixed it.
@@bernardocisneros4402 I found the problem, there was another connector just before the inertia switch that I didn't notice at first. Well that connector was partially melted on one side, so I replaced it and it works perfectly now.
Kings Adventure awesome, thank you sir, I found your video while trying to troubleshoot mine, mine ended up being the ignition switch. Thank you for your reply
