Ford Super Duty (1999-2016) :: 2006 - No Power To Injectors?

I have a 2006 Ford F250 super duty with the 5.4 liter gasoline engine. I started on a 120 mile trip last week and got about mile from home when it just shut down. I walked back home and got the wife's Tahoe and pulled it back home.

I got it in the shop and started to try & figure what had happened. I'm not a mechanic but I am a fair DIYer so I spent a lot of time with my friend GOOGLE. I originally expected the problem to be the fuel pump. I could not check fuel pressure because this model does not have the port in order to hook up the fuel pressure gauge. I could hear the pump run when the ignition was turned on so I looked a little deeper. I checked that it was firing and even shot some starting fluid into the breather to see if it would run with that, which it did.

At this point I turned back to the fuel supply. I learned from google that the injectors were supposed to have a constant 12 volts so out came the meter and low and behold no voltage on any of the injectors. I had already checked EVERY fuse on the truck and didn't find any burnt ones. I took the meter and rechecked all that had anything to do with the PCM (by reading the fuse description from the owners manual). My old eyes had actually missed the burnt one. Number 23 a 30 amp fuse. I replaced it and it immediately blew also.

I started checking continuity to ground on the injector plugs and found that I had a direct short to ground. I needed a wiring diagram for the injector circuit. I searched and searched some more for one that matched my vehicle. I even bought a repair manual from my local Auto Zone. This book didn't even have the diagram I needed! I finally found a diagram From Auto Zone's website for a 2000 expedition.

It at least gave me an idea of what other items were powered by this same circuit. I learned that the 02 sensors are on the same circuit so I crawled under the truck & started searching. I found that the up stream 02 sensor on bank 2 had gotten against the exhaust and created the short. I unplugged it and rechecked continuity to ground and found that my shot was no longer there. I took the sensor out repaired the burnt wire and reinstalled. I hooked everything back up and the ole truck fired right up.
