2000 F250 died, no power to fuel pump????

[Black Rock Trucks]

Hey guys, was driving my truck yesterday and came up to a stoplight and the truck died. No signs of it running bad or anything just died. Had it towed home and started looking at it last night. I changed the cam sensor, no effect. I then checked to see if the fuel pump was running, nothing so i replaced that still nothing. SO i decided to start testing the power wire and found that the plug wasn’t making good connection. So i cut the plug and reconnect the wires still nothing. What’s next??????? im trying to test fuese and relays now thanks kyle

Just realize, your pump is not powered All the time. The PCM turns it On/Off, through a relay, and the only time you're likely to see power in that wire is for the first few seconds after you roll the key from Off to Run.

If there's still no power then, then I'd be looking at the Fuel Shut Off (safety sw) behind the passenger "kick panel", then a fuse, then the relay (I think it's behind the radio in a 2000)

Do you have a scanner or programmer to read codes?

I ask because my truck did the same thing. Just died. Got it home and I went to hook up my programmer, it said it couldn't communicate with the truck. Led me to believe the PCM toasted. The shop tested it and sure enough, dead. $640 (parts and labor) later - all better!!!

I did the KOEO thing to listen for the pump as described above, no sound, no vibration.

Not saying yours is the same, but the symptoms sound familiar.

Yea, thats the only time i check for power. i have someone is the cab switch the key on and off.

I already check the saftey switch its down not in the up position.

Whoa!!! There you go.... Your PCM isn't running. Most likely, a fuse, most likely fuse #30 because of a shorted fuel heater. If so, unplug the heater element in the bottom of the filter housing and replaced the fuse. If not, look closely at fuses #19 & 22 and then Every Other Fuse.

Next, if you any type of tuning, remove it as a test. Then be sure the PCM connector is tight & dry....

Yup. It really shouldn't be dirty... but wipe the contacts with a dry paper towel or maybe a little alcohol on the paper towel. Make sure it's dry before you put the chip on tho. Make sure to mount the PCM WITHOUT the black box....and just tape the chip in place with electrical and/or duct tape.
