The cause of this is not the horn or fuse in most cases, it is caused by the rotating contact that connects the horn button, in order to repair this you will need a new clock-spring contact, to install the airbag must be disarmed, his has to be done by the book or serious injury can result.

The most common problem on a Ford V8 truck is the intake plenum gasket has distorted and maybe causing a major vacuum leak. While idling listen for a high pitched hissing noise. Buy a can of oxygen sensor safe Carburetor Cleaner. With the engine idling, spray around the center of the top half of the engine until you notice a change in the sound of the engine. Keep spraying to try to isolate the source of the leak....Be careful an follow the directions on the can of carb cleaner as to safety precautions...

Have you checked the 'inertia switch' which in the event of an accident shuts off the fuel supply to prevent a fire . It's usually located in the cab on pass. side. Some models have one reset button, some 2 which have to be pressed at the same time. If that's not it, here's how the power to the pump SHOULD work, you will have to follow the path to see where it stops. When you turn the key on it turns on the EEC power relay on, this relay then provides power to the PCM (power control module) and the control side of the fuel pump relay. Power for the fuel pump is supplied through a fuse link or high current fuse attached to the starter solenoid (battery side). From the fuse link or high current fuse current flows thru the fuel pump relay and inertia switch to the fuel pump. The fuel pump relay is controlled by the PCM. When the ignition switch is turned on the fuel pump will operate, if the switch is NOT turned to start position, the PCM will shut off the fuel pump off after 1 second. This is to avoid flooding the engine when it is not running, just key on. So check out to see if you have a fuse link or a high current fuse and if they are blown.

I had same problem on my 2002 explorer. Its either the computer module, or the electric solenoid on the transfer case. In my case it was both. The computer module I had done twice in 14 months.
