Blocked breather or over full, or damaged inside parts.

I'm not a qualified Ford tech but if I remember right, those vehicles won't power the fuel pumps until after the computer sees signal from the distributor. Does the truck have spark?

First, have the tire inspected before you do any expressway driving. you could have a damaged tire with a tread or internal ply separation. second, inspect the front shock absorbers, it sounds like the left front shock has failed and lost its hydraulic fluid. third have the front steering linkage and front suspension checked for worn or loose tie rods, idler arm, ball joints and stabilizer bar links. do this ASAP as you don't want to have the tire fail or any parts break while you are driving!

BOTH ANSWERS ARE GOOD BUT THERE IS A FUSIBLE LINK WIRE ON THE STATER SOLINIOD THAT MAY BE BURNED OUT LOCATE THE FUSIBLE WIRE AND GIVE IT A LITTLE TUG, IF IT STRECHES IT IS BAD MAKE SURE YOU REPLACE IT WITH ONLY FUSIBLE LINK WIRE

the fuel pump reset button(inertia switch) is above the pass side kick panel

Spray the bolt with PB Blaster a few times and let it sit for awhile. Use a screw extractor on the broken shaft.

It does sound like you have something that is draining the power from your battery overnight. I had the same problem with a car I no longer have and I went through all kinds of checks to see where the problem was. It wasn't until I went outside one night to put the backrest on a rear seat into position where someone could sit there. To my surprise, the trunk light was on. I fixed the problem (a bad switch) and never had a battery problem after that. What I am getting at is that one thing you should do to check out the car is to look at it when it is dark outside. If you have a hood light, that might be staying on. Even the interior light might be staying on and you don't notice it during the day time. Also, check your bed light to see if that is staying on. If any of these are the problem, a simple adjustment or switch replacement will cure the problem.

here you go if it doesent show up go to autozone library that's where I got this one.

all red lights are danger stop yellow lights are caution check system then continue on.

There is a switch located on the brake pedal itself, it is located at the top near the pivot point. It is a black switch and will have two green/red wires plugged into it. One side should have power at all times and the other will have power when you press on the pedal. If you have power on the one side and nothing on the other when the pedal is depressed you will need a new BOO switch. If the switch is working properly then you have an open wire between that switch and the rear of the truck. I'm not sure of the condition of the truck but going by the year I would make sure you don't have a ground wire that has rotted off at the rear of the truck.

if it is the lower ball joint it presses out the bottom. rent a ball joint press from local parts store (refundable when tool is returned) and it is simple if you have an impact or electric impact ($75). put the press stud on the ball joint stud and ring underneath. If you never have used one, they will explain how while you are there.

You have a vacuum line that feeds the selector on the dash. It runs thru the wiring harness.There is a vacuum ball under the hood. One line goes to the engine the other to the selector switch. Check for breaks in the line. If none found, it is way easier to run a new line from the ball to the switch.
