RATS!
Alright guys, if y'all can help me, I'd really appreciate it and I'll buy the beers if you make a trip to ga sometime haha
I have a new to me 1989 bronco II with the 2.9 in it. Rats have seemed to have chewed through some wires running the fuel pump and I have no clue where they go. 2 wires, 1 is purple, the other is purple with orange tracer, damn rats chewed it out of the heavily taped wrapping. This is on the driver side just beside the ignition coil and on the quarter panel wall. The same set of wires that runs behind the radiator reservoir.
The set is just beside the starter solenoid to the left and it comes off of a relay. It's a red wire and a blue wire.
This is the last one it's a blue wire and it's just above and to the right of the heater core and it comes through with a bunch of other wires but that's the only one in the convoluted tubing I think that it goes over to the one with the second picture blue wire but I'm not a hundred percent sure.
any help would be greatly appreciated I'm waiting on my girlfriend get back with the Haynes manual so that I can try to track this down on my own but any help would be great. Thanks guys!
EDIT: found another set of wires by the air box that are chewed up bad
It appears to be a yellow with red tracer, green with brown tracer, pink with green tracer, black with white tracer and brown with red tracer, maybe it went to a relay harness??

mice/rats and wiring are the worst. I hear that the newer vehicles with biodegradable soy wiring insulation taste even better to mice... so at least you don't have that problem. I have found the haynes manuals to be useless. A Ford service manual that you can buy at online auction sites has the diagrams that work based on the year you have. What you may need to do is cut off a lot more of that wiring loom and get back to wiring that is clean and fresh, then compare colors on both sides. Wiring that hasn't been exposed can have a very different color. Good luck

well I'd appreciate it if you could take a peak and just see if you got same color wires(purple and white and a darker purple and white). May go to some sort of light or something, I honestly have no clue. And yeah, it was a pain to drop the tank, was about half full haha, and of course the bolts were rusted to hell and back. Your brass float may have fallen off in the tank if you have been doing any offroading. But definitely order a new pump and sender unit off of amazon, autozone here was gonna be about $200 for full setup, amazon was $103. Mine will be here tomorrow so the ol lady and me get to get down and dirty... then maybe we will put the fuel pump in haha

Alright, got the new pump in and sending unit, now I am getting plenty of fuel pressure. Still won't start, all plugs firing, will try to start but it's like it's flooding it. I'm thinking fuel pressure regulator cause there is fuel in the vacuum lines. That's gotta be a busted diaphram right? I have a good battery and fresh gas, so it's gotta be, from what I can figure, either injectors or fuel pressure regulator, but as far as I know only the regulator would allow fuel into vac. Lines. Opinions??

I agree that the regulator sounds bad. I would hook up a noid light to the injector plugs and see if it pulses, then you will know for sure they are good. A full set of injector noid lights is really cheap on amazon and I have used mine more than I thought I would. I looked yesterday at mine and I don't seem to even have those wires in that spot. You want to compare to another fuel injected one for sure. My last thought is this: a few years ago I bought a 1982 Corvette for 2 grand because the owner had rebuilt the fuel injection system, rewired stuff and spent a boatload of money trying to make it run and gave up. Turns out his new spark plugs had fouled out from fuel soaking. Changed them and enjoyed cruising the next few years in a cheap Vette that ran great. Perhaps if all else fails, your plugs could be bad.
