It is located on top of the fuel pump sending unit/module which is mounted in the top of the gas tank. If some of the work you have had done recently was a fuel pump, then quite possibly whoever did the fuel pump forgot to plug in the pressure sensor or they broke off a terminal in the sensor when plugging it in.
A little trick. Its possible that you can reach on top of the fuel tank with the tank still installed in the truck. If so, unplug the sensor. If you need to replace it, you can pull up on the sensor enough to remove it. Spray some kind of lubricant on the new ones rubber gasket and reach on top of the tank again and stick it in the hole. Just make sure it gets mounted all the way in the hole. If the bottom piece of the old one breaks off and falls in the tank, dont worry. It's too small to do any damage.
You just saved yourself about $300 in labor /wink
