Drove the 'ol girl home 3.5 hours on Friday. Went to start her the next day, the engine turns over but doesn't fire. I noticed that the fuel pump isn't priming when turning the key to the 'on' position.
Did some research and come to understand that 2014's control the fuel pump through a Fuel System Control Module that's located above the spare tire. All my fuses are good, so I'm left with either replacing the FSCM or the pump.
Normally if I can't isolate a failure to the component level, I start with what's easier/quicker to change/test. In my case both options suck.
The fuel pump is a couple hundred bucks and looks to be a several hour job to drop the tank and replace the pump. The FSCM replacement looks to be pretty quick (unplug and remove/reinstall) however the new FSCM will require it to be programmed to my VIN. I don't have the equipment to do this (although I'm familiar with PCM programming and have used HP Tuners to program a different car) at the moment and the FSCM + programming cost as much/more than the actual fuel pump.
Anyone have suggestions on how to isolate the FSCM from the pump?
