There is either a dead short in the loom but most likely the fuel pump relay has failed.

Diesel. Reduce power lite turned on. Shut off engine and started back up - lite is off. Can it be driven?


Jerry, Drive to a good shop. So many things can cause reduced power light unfortunately. The first step would be to get the truck hooked up to a scanner/computer and have the computer scanned for trouble codes. One thing that you could try is to drain the water from the water separator that is mounted on the frame under drivers front door. If the PCM picks up on water, power is reduced until water is removed/drained. It could be an exhaust sensor that is reading faulty. Unfortunately from here its impossible to tell you exactly what the fault is because there are just so many engine sensor inputs that could cause your problem. Check the attached links, forums,instruction and guides, Good luck

What is the pressure of the locking front hub when doing the leak test On a 2000 ford 250 super duty truck


The 4x4 system works on vaccum and not presure. If this is not a Diesel you may have a vaccum leak. Check your vaccum hoses from the wheeles back up to the intake for cracks. If this a Diesel Super duty the 4x4 system works off a small vaccum pump out under the hood on the passanger side right over the tire. There is no pressure it is vaccum. Run the A/C and see if the A/C is blowing up on the windshield or out the vents were it should. Change it to the floor and see if it changes, If it does not change the vaccum pump is not working. Check your fuses first. If they are ok check for voltage at the the vaccum pump. Check your ground as well. If you have voltage and the ground is ok the pump is bad.

Fuse #2 in the fuse box behind the driver's knee panel is the 5amp "KAM" fuse. The others,in under the hood fuse box would not be a concern as without them being good the engine will not start and no code read would be possible.

Pcm or computer fuse location, where is this fuse so I can check to see if blown?


It should be in the under hood fuse box with a PCM protection diode and PCM relay. Is your truck light duty, super duty, gas or diesel?
