Hey, my wife called me yesterday and said the truck died, I showed up, it was obviously out of fuel. It's a 2000 F-250 7.3 PSD. I added 18 gallons of fuel and replaced the fuel filter. I cycled the pump 4 or 5 times but it still wouldn't fire. I tried opening the valve on the back of the fuel bowl with the pump on, nothing. It seems like the fuel pump isn't pushing any fuel. It's making a whirring sound but it doesn't sound like it's picking up fuel because it doesn't bog down like it's building pressure. I know 18 gallons has to be enough for it to pick up, even after it was run dry. Any suggestions? We are stuck with one vehicle right now and it's very difficult for us. Thanks!!
