I was driving my 97 dually and was going through the gears pulling my boat, and all of a sudden the truck started to shutter and shut down. I coasted to the side of the road, and it died. It wouldn't restart, so I thought that the fuel filter plugged. I changed it, and it still wouldn't fire. I bled the the lines to the injectors and still no go. I did the big no-no and used a shot of ether. She would pop off, clank, smoke, and die again. After letting it set for a few hours, it finally started, but it poors out grey and blue smoke. It won't hardly idle (400 RPM), and when I get the RPMs up, it clanks worse than when it is super cold out. It has just enough to move down the road, but I could only get about 6 psi on boost. The egt's went up, but I'm sure that's from the lack of boost. I don't have a fuel pressure guage on it (yet), but I'm thinking the lift pump went out. Help please.
P.S. I have a Prime Loc fuel filter relocator kit on it. Does anyone know which port on the filter block will tell the pressure after the filter?
