All Crank No Start
Hey guys I am new in this section and need some help.
My dad has a 2007 F150 3v 5.4 and he parked it last night and it was running just fine. We went to crank it today and it fired for a second then died.
I am getting spark and the fuel pump is coming on. I checked all the fuses and fuel inertia switch and they are good too. Oh and it isnt pats.
Thank yall in advance for any help.

I know you said you hear the fuel pump, but drop the spare tire and take a look at the fpdm.

I had to leave it up at the office but I will take a look when I make it back up there in the morning. Will that stop the pump from pumping effectively even if I hear it turn on?

It did with mine...it was a quick death. I would hear (or think I heard) the pump kick on but it would crank for a bit - and finally start. Then a few days later, crank and no start. Thankfully I found the link that is shared in this thread - bought the item online and swapped it out. My original was so corroded it was hanging down from the frame. 10 minutes to swap out (8 of which was getting the spare tire down - long story) and viola - fixed!!!
Good luck!

For around $60, it's not a bad idea to swap out. This is the one I got for my 2004 - think they are all the same for newer models but just be sure. The replacements come with spacers that keep the unit away from the frame and helps avoid corrosion.
The other thing you may want to check is the Fuel Shutoff Switch. It's located behind the passenger side kick-plate next to the fuse box. I hear tell that sometimes it gets "activated" which shuts off fuel to the engine. (supposed to only activate in a crash). Just make sure the button is pushed all the way down. Look in your manual for full details.
edit: sorry...just re-read your original post and saw you checked the fuel switch already.
