I have a 2002 F-250 SD V-10, 21,000 mi. It is not run every day it is a second vehicle. I recently went to start it and the battery was dead. I tried to jump start and it barely would crank. I then took out the battery and put in another. It then cranked great, however it would not start. I checked the fuel pump reset and fuses all was ok. I know I must be missing something here. Does anyone have any ideas? Thanks.
Fuel injected vehicles are programmed to only run the fuel pump for a few seconds until the engine starts. If it doesn't it will turn off. Sometimes you have to let the fuel pump cycle 3-4 times before it will build fuel pressure and start. I have a auto-x car that is EFI and it has this same problem after it sits all winter. Sitting is probably one of the worst things for a vehicle, I usually drive my truck to work twice a month if nothing else so the gremlins don't move in.

I haven't used the truck in a little over a month. Do you think the computer lost its memory due to the dead battery? Should I hear the fuel pump prime the injectors when the key switch is in the on position? Tomorrow I'll check for fuel pressure at the rail.
Is that on the passenger side behind the kick panel? If so I tried to reset it and it seemed not to move when I pressed it. It seems to be in the reset (down) position.
Do you hear the pump running in the tank at all ?
if not take a 2x4 and tap the bottom of the tank and see if the pump starts running .
There have been a few in the past that after sitting become gummed up.
you are sure you have fuel in it ? ,put some in the fuel gauges can get stuck at a level even if the tank is empty.
Also just touch the gas lightly if the pump is running ,could be a bad IAC valve totally plugged up.

Well I checked to see if there was pressure at the fuel rail schrader valve. There was none. So next is why. I'll put some more gas in the tank and start bang'in in it to try to wake up the pump.
21,000 miles shouldn't be the CPS. Parking a vehicle for extended times can be a huge problem. My dad has a motorcycle shop and you'd be amazed at the weird and humorous things we have found in bikes stored during the winter that don't run.
Airboxs packed full of dog/cat food, rags, and craft beans, by rats/mice, chewed wires, etc. Should have seen the customers face when we showed him all the dog food that was in his airbox lol!
Well I'm still looking for the problem. I'm glad this is not my daily driver! Anyway I'm trying to locate the fuel pump relay. Does anyone have any idea where it might be? I have a haynes manual and it says it is behind the radio, I don't see it. I have a new one and can't find anything that looks like it. Any help is appreciated. V10 2002 SD crew short bed. Thanks.
Copied from the manual: FUEL PUMP SHUT-OFF SWITCH FUEL RESET
This device stops the electric fuel pump from sending fuel to the engine when your vehicle has had a substantial jolt. After an accident, if the engine cranks but does not start, this switch may have been activated.
This switch is located in the passenger’s footwell, by the kick panel.
To reset the switch:
1. Turn the ignition OFF.
2. Check the fuel system for leaks.
3. If no leaks are apparent, reset the switch by pushing in on the reset button.
4. Turn the ignition ON.
5. Wait a few seconds and return the key to OFF.
6. Make another check of leaks.
There are many things besides an accident that will trip this safety switch. Page 159/160 has a picture of the switch.
Fuse #40 is for the fuse pump. It should also be checked.
