Crank but no start 1 day. Starts fine the next.

Crank but no start 1 day. Starts fine the next.
2004 F250 V10, approximately 75,000 miles.
Here’s the story.
Last Saturday I go to Home Depot early in the morning, Stop the truck twice, get stuff, restart it and everything is fine.
Later in the afternoon, the wife takes my truck back to Home Depot to get something. I get a phone call a half hour later saying truck won’t start. I go over there and it’s dead in front of the store. I try starting it a few times. It cranks for about 2 seconds then nothing.
I end up pushing the truck into a parking spot away from the crowds and go back home. About 2 hours later I go back with some tools to try a few things including: swap A/C and FP relays. Check fuel shut off button, check all the fuses, fiddle with security system.
There for about an hour. The whole time the truck will crank forever but not start. Parking lot and busy road so I can’t hear anything let alone something like the fuel pump clicking.
Anyways, had enough playing parking lot mechanic. So I go home and end up having the truck towed to my house. After the tow truck drops the truck I try starting it and once again it cranks but no start.
The next morning I go out and start getting all the tools I left in the truck out. Have my keys in my hand so I figure let’s see what happens.
Damn thing fires right up. I end up leaving it running for 20 minutes or so including driving around the block.
So now I’m at a loss. I can’t diagnose a problem that currently doesn’t exist but I also don’t want to drive it because it might die somewhere again.
Any suggestions?
P.S. New battery, spark plugs and starter in the last 3 years. Other than when the old starter and battery died (2 separate occasions) I’ve never had any other problems in the 8 years I’ve owned it.

sure sounds like the fuel pump to me if it happens again you can try hitting the fuel tank and see if it will start or you can start turning the key on first without starting like waiting for the glow plugs in a diesel and see if you hear the fuel pump when it wont start you wont won't hear the pump if thats what it is if you buckle the seat belt the truck won't make all the annoying beeps when you turn the key on.

Crankshaft sensor should throw a code you can rent a fuel pressure test kit make sure it has the right adapter. If it's not doing it then there is nothing to eliminate currently while doing the fuel pump is going to suck there is no easier diag then turn the key and listen if the fuel pump does run then it would make sense to look at other possibilities but this sure sounds like its a fuel pump.

Just to update this problem.
Changed out the fuel pump and filter last weekend (after finally getting the right pump)
Started every time for 6 days in a row, let it run for 10-15 minutes in the driveway then shut it off.
Finally grew a pair and drove it back to the scene of the crime, Home Depot.
Drove fine and started each time.
So hopefully.....problem solved.
Thanks

I've also had this problem with my truck dying out for the last few months. Read through different threads that all pointed to the fuel pump. So I changed the FP, worked fine for about a month, then truck started acting up again. Took it back to the shop and they couldn't diagnose anything except "it's probably a bad fuel pump." Replaced the FP again since it was under warranty. Worked fine up until today where it died on me again while driving. I'm at a loss. But I will check the crankshaft sensor. ANy other suggestions? Thanks for any help.

They arent really expensive to do you can go aftermarket but I would recommend the FoMoCo OEM one because they are pretty worry free. Just a thought

He called and was only a couple blocks away so I towed him to my house. No power to the inertia switch so I replaced the fuel pump relay behind the radio. It started right up and it ran perfect for 3 weeks, til it died again and would not restart. No fuel pressure, no power to the inertia switch, no power to the relay.
Got some detailed schematics from the factory service manual, thanks to a friend that is a tech at a local dealer. Luckily the problem didn't correct itself right away this time, I traced backwards figuring how each circuit was powered from another, then another and finally found I didn't even have power to the ECM. I finally traced back to a 30 amp fuse in the under dash panel that seemed to power everything. As I tested it had power on one side and initially no power on the other. Figured it was just being difficult to get a good connection with the meter, as I moved the probe it suddenly it powered up and I heard a click and the fuel pump ran. Everything had power and the truck fired right up.
I had tested all the fuses numerous times on several occasions. I pulled the fuse out and it looked to be fine. Grabbed the terminals, one seemed a tiny bit loose in the fuse itself so I put in a new fuse. As I fiddled with the fuse I realized I could make and break continuity through it. I used a sharp wood chisel to split the plastic shell off of the fuse and the terminals fell apart. It had an almost invisible hairline crack right down the middle of the fuse link.
Thinking maybe I just broke it cutting it apart, I pulled out a new one and split it. A 30 amp fuse is tough, I definitely did not break it. New fuse in, the truck has run perfect for about 2 years now. He spent over a grand on towing, fuel pumps, labor and was left stranded dozens of times over several months, all over a 50 cent fuse.

Not sure if I am able to reply here but I have a similar problem in my 2001 F250 5.4. Usually my truck will start up first try when its cold and run perfect. If I shut the truck off and try to start it back up again, it will occasionally idle for a second or two and then die. It'll crank and crank but will not fire over. It only does it on start ups. It has never died on me while driving. Even at stop signs and red lights it idles perfect. I thought it was the IAC so I replaced it and it did not cure the problem. Now I'm thinking its fuel related. Iamrfixit; which fuse did you pull to address your buddy's issue?
