Could be the fuse for the horn, the horn relay or the clock spring in the steering wheel column.

Best to start with jumpering the horn relay, to check the horns to the fuse.

Take a jumper wire, and jumper across the normally open contacts in the horn relay socket ( listing in the owners manual ). This is shown as the red line in the picture below.

If the horn does not work with the jumper wire, check the fuse ( engine compartment fuse # 7 ) with a meter. IF the fuse has power on both pins on the back of the fuse, next is to install the jumper and test the horn connector for power & ground ( Yellow w/ light green is from the jumper in the relay socket and black is ground ). If you do not have power using the Yellow w. Light green wire & the black, try another ground, to see if it is an issue with the ground wire. This is to a ground lug on the passenger side inner fender.

If the horn does work, check pin #2 with a meter set to continuity from pin #2 ( diagram above ) and a known good ground. While checking this, have someone press the horn switch on the steering wheel. If you do not get a low resistance (

You most likely have a bad spark plug coil and or plug. First recomendation go to your local parts store and have them put a code reader on it. It should tell you what cylinder is missfiring under load. Once you identify replace the coil. Cost $45-$60. Also replace the plug. After this you should be back in business. This is common with the 5.4L engine. Depending on the cylinder involved the coil can be difficult to get to so take your time. Definently and easy do it yourself repair.

Good info on the PATS / theft light. Looks to be the PATS / HEC operation is functioning correctly

The Fuel inertia switch only cuts power to the fuel pump, so if tripped, the truck would have a crank no start issue. Do you have a crank no start, or no crank issue.

To reset, just press down on it. To check if the switch is tripped, check for power at the connector to the fuel inertia switch

Engine compartment fuse # 10 ( 20A ) to the fuel pump relay -> Dark Green w/ yellow stripe wire to the fuel inertia switch -> pink w/ black stripe wire to the fuel pump module.
Check the pink w/ black stripe wire to ground with a meter for power, with the key in the run position.

If you turn the key from off to run ( do not start ) you should hear the fuel pump cycle ( hum, then turn off ).

Could be an issue with the fuel pump relay ( my '01 had a crank no start at ~ 35K miles, bad fuel pump relay ). I proved this out ( after a stupid ID10T error in my diagnoses process ) by jumpering the normally open contacts in the fuel pump relay socket, and then installing the trailer tow reverse circuit relay into the fuel pump relay socket ( same full size Ford Relay ).

Jumpering the fuel pump relay in the relay socket ( remove relay and use jumper wire ), red line

If you have a no crank issue, could be the DTR ( Digital Transmission Range ) sensor on the driver's side of the trans is out of alignment.

Check the start motor relay ( on the firewall on the passenger side ) for power on the Tan w/ Red stripe wire when the key is in the start position ( this is from the ignition switch through the DTR when in park or neutral to the starter motor relay ).

You can test another route, turn the key to the run position, and apply power to the Tan w/ Red stripe wire on the starter motor relay in the engine compartment on the firewall. BE CAREFUL, the motor should turn over, keep clear of moving parts.

Post back a comment to this problem with the results of the testing.

Do you have another key to try ?
The flashing theft light during the crank is indicating the key is not programmed to the truck.
When you get the no crank no start, do the cluster pass the power on tests OK ? ( i.e. all the indicators light up, and then go out, oil would still be on with the key in the run position with the engine off ).

It has two solenoid I think. Check all your connections again. Tug on the wires to make sure they won't pullout of the connections.

There is a relay, but I doubt that is the problem. You need to troubleshoot when it is not starting. Is the fuel pump running? Are you getting sparks?

Change the bulb. When you press the pedal the brake switch changes the circuit to the 21w brighter circuit for the brake light.
