I am looking at a decent 1998 GMC 3500, 1 ton 4x4 extended cab dually truck.

According the seller, this truck is sporting a 6.5 Turbo engine out of a 2000 model rig.
The original 6.5T was "blown up" and it's carcass comes with the sale.

All was well until recently, then it "stopped getting fuel".
The seller does not to mess with it.
Now, I do not know if that means the IP has failed and the injectors are not getting fuel or what.
My guess and my hope is that the lift pump has failed, a common issue and the IP is not getting enough or any fuel from the tank.

HUGE IF, the lift pump is the problem, then this could be a quick, easy and inexpensive repair.
This would also mean that this truck could be a great deal and could be had for a low cost.

Comments? Thoughts? Opinions? Flames?
