99 F250 7.3 no power to fuel pump
I have a 1999 F-250 superduty 4X4 with 7.3. y ruck died on me the other day while driving down the road. I had it towed home. I checked the fuel kill switch it was fine, checked fuel filter in ok shape, checked fuel pump no power getting to it, pulled it and hooked it up word good, changed relay in dash behind radio, still no power to pump any ideas would be appreciated.

Welcome to 
.
Here's a thread started today about the same problem. CLICK HERE
For a 1999 Under hood fuse #19 for fuel pump.
If you are not getting the WTS lamp check under dash fuse #30 for PCM and fuel bowl heater.
If the PCM is down it will not be able to turn on the fuel pump.
Any questions just post back.

thanks a lot, my truck has been down for a few weeks. I cant believe all it was was a damn 30 A fuse. Some mechanic I am. and I always tell my customers to check the cheapest and easiest things first. Whats cheaper and easier that a fuse. I guess I was just frustrated.

The fuse most likely blew due to a shorted fuel bowl heater. Did you unplug it before replacing fuse? If not, do so, or it may blow the fuse again.
Edit: Don't be a stranger. A lot of great people and a lot of great info here.

yes I unplugged it earlier trying to see if that was the problem, I have a small leak just above the heater I have been trying to fix it also. I replaced one o ring then found another leek near the one I replaced. What is that thing called that is behind the filter housing above the heater?

If you live in a warmer place simply leave the fuel bowl heater disconnected. Bit of tape to keep the connector clean.
I'm in Central Valley of CA, freezing is rare. My fuel bowl heater was fine so I pulled the internal connector and tied it in a knot. It does not work but it also cannot cause a short and blow a fuse now. If I ever need it I can simply untie the knot and connect it.
