2008 F150 lariat supercrew was running fine never a problem, parked it Saturday night and next morning tried starting and all it would do was crank, I reset the shut off relay switch to the fuel pump to no avail, any ideas out there?

Do you have fuel pressure? The FPDM could be all corroded.
Here is a thread about it...

Are you parked on a incline ? I had same problem the other day with more than 8 gallons still in tank, fuel pickup is at back of tank and I was on a incline so it wouldn't reach. Coasted down to flat ground and started right up.

I unhooked the hose from the fuel filter and turned the key to on and I'm assuming that gas should have flowed out the hose but all that happened was a little bit dribbled out of the filter, I went ahead and ordered the part you shared with me on amazon, it was $58.00 and since I haven't replaced the Spark plugs and 1 of my coil packs was bad, I went ahead and order them as well, (Accel Supercoil's) of coarse I won't get them till next week but I saved a hell of a lot of money by going through Amazon... Thank you for the input I'll let ya know how I made out!

You should only use Motocraft ignition parts on these trucks, anything else is a step down.

I am having the same problem with my 2003 f150. Any ideas where to start?

Not according to my Ford mechanic, Autolite's new OEM design (HT15 High Thread Sparkplug) is much better then the Motocraft in that they are more efficient and won't break off when removing, he also highly recommended the Accel Supercoil over the Motocraft Coil packs.

The FPDM came yesterday, I immediately put it on, and my truck fired right up!!! Thank you!!!!

Check to see if you have fuel pressure, if not do the same thing I did, replace the FPDM, worked for me!! Amazon has the Dorman for $58. https://www.f150forum.com/f4/fuel-pum...-yours-152908/
