Fuel Filter empty
My truck had been sitting about a week and I started it to carry some trash out to the dumpster. It cranked fine and drove about 100 yards then the engine revved a bit then died. It acted like it ran out of fuel. Both tanks are full but I switched tanks and tried to restart. Nothing. Pulled the fuel filter and it was about half full. I refilled it and the truck fired and ran about 20 seconds before dying again.
I am thinking that the mechanical pump could have failed. Is this a good place to start?
When cranking over I do not get any fuel out of the schrader valve on the filter head.

I checked the lines from the tank past teh selector valve and did not see any evidence of a fuel leak. I know that it can leak air but not diesel. When I get a chance I will crawl under it and pull the lines from the pump and check it. Probable won't be until Friday since I don't get home from work until well after dark and the truck is in the parking lot of the apartment with no outside lighting.

An air leak on that side of the pump, unless it is real bad usually doesn't have a wet spot, I have had to pressurize lines more than once to ever get fuel to leak, to find it.
If you happen to be able to get a piece of host to hook to the steel line on the frame by the pump, and siphon it you can usually rule out an air leak. You may have to spit out some diesel though and it tastes terrible. lol
