My truck all the sudden didn't want to start. It'll crank over but not fire, and no service lights or notifications on the gauge cluster, so I hooked up my scanner and got these codes... what are these and what should I be looking for?
There is a known issue with our model trucks where the fuel pump fuse, fuse 27, in the under hood fuse box on top of the radiator, 20amp fuse, will not blow, but the bottom of the fuse and socket contacts will melt.
you need to open the hood, open the fuse box cover and pull f27 and look at the bottom of it and look down on the socket for evidence of burn and melting.

Ford issued a TSB, technical service bulletin, a few years ago, that includes instructions, wiring, and new fuse, to relocate F27 to another slot with "heavier" load abilities.
the TSB kit cost about $20, and takes about 30 minutes DIY
you can google TSB 15-0137. There are many threads posted here.
if the fuse and socket look good, your problem could be the fuel pump driver module, also a common problem on our trucks, located under frame near fuel tank.

I was going to pull it inside with my other truck to check it out and since I had to turn the key on to put it in neutral, I was curious if it'd start this time, and it did. I then drove it in and checked fuse 27 and see it was starting to melt. I looked inside the socket and it looks just as clean as the rest. I'll have to get a new fuse tomorrow to make sure that's the only problem.
