fuel vaccum

[pipelinetrash89]

Ok guys, my truck died this morning and I checked the fuel filter housing to make sure it had fuel. I found out that it didn't, so I filled it up with diesel and she fired right up until it emptied the bowl out. So i filled it back up and it wouldn't start until I cracked the valve on the filter, and I heard a vaccum. It started right up and ran fine until I closed the valve and it died again and it was out of fuel. Is it possible to have a vaccum in the fuel system?

Yes, try loosening the fuel cap. Non working lift pump, oil pressure sender (ops) or a plugged tank sock could also be your problem.

I just changed the ops, and the lift pump. I loosened the fuel cap and no help there. But now it won't even act like it wants to crank! I have a new pmd in the mail on the way, with new injectors and glow plugs. So do you think I need to just change the IP while I'm in there?

IP is last resort unless you have a bunch of $ you don't care about.

Well I got it all fixed up. It was the lift pump again, I just changed it 3 weeks ago. This time I put on one from a 93. Well the truck makes $16 an hour right now, so an IP is cheap cause it'll make the cost of it back in just a few weeks.
