1988 Ford Bronco Fuel Pump/Computer

Electrical problem
1988 Ford Bronco 6 cyl Two Wheel Drive Manual

I"m without a vehicle because, to make the story short, my inertia switch on the bronco II kept getting hot and tripping so I just wired it together. Well, I was dropping my friend/babysitter off and I guess the tape fell off of the wires because we both saw sparks by her foot and the truck just DIED in mid-traffic never to start again. (Her shoe touched the bare wires or something)

Before it had to be towed away from my rented property, I have checked the relays (switched out with good ones) fuses, and listened to the pump--which does the usual short whine when it comes on. I checked the only fuseable link I could find, coming from the negative battery line. What I am guessing is the computer got spiked. When I try to crank it, the engine turns but that is it. No fuel is getting to it.

What I want to know is what is the black box behind the driver's seat (on the wall) control? I cannot afford a book right now and my car was towed to the junk yard. Is it likely the computer(s) got fried or do I need to replace one of the fuel pumps?

I have basic tools, I am low on money and a single mom that doesn't know a lot about cars so I would greatly appreciate any help at all, even just links in the right direction. I cannot afford a mechanic. Thank you so much in advance to anyone who helps with this.

Do you
have the same problem?

If you hear the pump come on but have no fuel pressure, the pump is bad or the filter is completely plugged. Disconnect the fuel filter on the tank side and turn the key on. Gas should shoot out. If it doesn't, the pump is bad.

Also, I want you to try one more thing. See if it will start for a few seconds using starting fluid. If it does, that will confirm my beliefs.

Let me know what you find.
