Ford Repair: 2006 expedition, push pins, fault code reader

Question
I was driving down the highway and my accelerator wouldn't respond when I pushed it down and then finally died when I pulled over.  The fault code reader indicated that p0191 was the problem.  It will start but then immediately dies.

Answer
replace the fuel pump driver module. it is located just over the rear axle. if you remove the left rear tire and a small cover, held in with a few push pins, you will see a 2x6 grey module with a 5-6 wire connector going to it. this is what controls your fuel. they get corroded from road salt debris etc...
