Check your Collision switch, reset it by pushing the button on top. Switch is located under the dash on the firewall to the left of your left leg. Check your circut breaker and fuses.

1993 F150, 4.9L engine, 4X4, long bed, std cab.
I shut it off last night with about 1/8 tank of gas in the front tank. This morning it would not start. I switched to the rear tank and it started. I filled the front tank and put gas in the back tank as well. It still will not start on the front tank. I checked the collision fuel-shut off switch. It is depressed and ok I guess; I've never seen one that had activated. It will not run on the front tank: I switched tanks while driving and had to switch right back to the rear tank. There are no fuses in the fuse box inside the cab marked for fuel anything and I don't know where or whether there are more fuses.
The only thing different to me from the day before is that a shield on the exhaust had come loose a few days ago, so I put new bolts in it last night. I can't think that I was any where near any fuel system components, but then, I wasn't looking for them either.
Any help on what the problem is?
THANKS IN ADVANCE.

Ford did two different designs on that. One they used a rail mounted fuel pump driverside slightly forward towards the engine that pulls fuel trough the selector valve also on the rail drivers side about where the bed starts. Look for damaged wires at the selector valve from that exhuast sheild that fell off. It may have cut one of them.
If you have the design of two fuel pumps, it is probably the pump.
Your inertia switch kills power to your fuel pump[s] reguadless what design. If one is working, it is not that.
Be focusing on the selector valve. Good luck

The exhaust shield is on the passenger side right beside the tranny. It didn't fall off, only lost a bolt & rattled, so no cut wires from that.
When you say 'rail mounted' are you referring to the frame? I just put all new brake lines on and don't remember anything with wires (selector switch or pump) on the frame, but I'll look again. There is a fuel filter in the gas line that lays inside the frame about even with the drivers floor board.
I don't know where the fuel pump(s) is, but I assumed one in each tank.
Thanks for your comments.

I am having a problem that while driving my truck the check engine light comes and the engine dies. When I go start it back the fuel pump just runs and does not shut off, could someone help me with this and please tell me what the flat pancake contraption is up next to the fuel injection manifold.

Can you retrieve the trouble code from your computer? If so, this will narrow down the problem. Are you sure you are not out of fuel? Not sure what the pancake contraption is in less it is the fuel back pressure regulator. The regulator restricts the amount of fuel returning to the gas tank, forcing more fuel to the injectors, thus making more fuel inter the cylinder to make it go faster. I suggest going to your local automotive parts store and pick up a Chilton (or equivalent) manual #266664 which covers 1987-1996 Ford Pickups. This manual will help you alot and only costs around $20.00. What engine do you have? Is there a vacuum line going to the pancake thing and is it hooked up and in good condition? Check all of your vacuum lines and wire connections before doing any repair work.
