You need a large group of people to call Ford because your F-150 won't start? It is not a big problem as far as I can see.

Bob, I believe he is referring to a very specific problem which seems to have been going on in a lot of late model Ford/Mercury product. It is posted in several other threads on this site with no true resolution. The vehicle in questions starts having crank, no start issues and seems next to impossible to definitively diagnose. It now appears that it is linked to the fuel pump driver module. In some cases it manifests by overheating the fuse to the fuel pump relay which powers the fuel pump. I just successfully solved the issue on my 2009 F150 after months of random crank, no start episodes. Early on it manifests after the vehicle has set for about 6-8 hours. Late in the game it get even more unpredictable. Mine caused damage to the underhood fuse box. The fuse rarely blows, it just gets hot and melts the fuse casing and possible the fuse box.

Don't be a troll bob!

Thanks to LarryM70. I experienced my 2009 F150 5.4 V8 starting in the morning, drive to town and when the truck was turned off, it would not start for an hour. Here is the melted 20a fuse for the fuel pump relay. Duke@66749

Well it worked! Have a 2010 F-150' that would crank but wouldn't start. Have 91,000 miles and never had any problems till now. Found the 20 amp low profile fuse for the fuel pump relay, pulled it and it was fried. Replaced it with another one and it started right up. Saved me probably 200-300 dollars. Thanks, Scott Meadows

I just wanted to say thank you to you guys. I walked out of the store to my F150, 2010 and had the above listed problem. I thought what have I got to lose before I call a wrecker. Sure enough fuel pump relay fuse fried. Pulled the 20 amp from the trailer light relay slot. Truck started right up. Got to parts store. New fuse boom I'm running again. Thank you for being here and doing what you do.

happened to me too. 2015 F150.
