Hard Start...Now NO START

Morning Guys, a month ago or so I posted about a sudden hard starting problem and was advised to look into replacing the rubber fuel return and supply lines as well as the lift pump...all were overdue to be done, 125,000 on the truck.

Did that work...half day of fun

Truck immediately ran much better and quieter, the old lift pump was making quite the clatter...all better.

A week ago started to loose "prime" again on the fuel system to the point where I have to manually prime the engine every time I start it up, and now it is to the point that it will stall if left to idle for more than 5 min. or so.

Air gets into the system so fast now that the engine cannot be re-started after it is shut down without using the primer on the lift pump.

Did the new lift pump fail already??? That seems plausible but unlikely.

Any ideas as to what I might have done wrong???

I do hear air bleeding from the vicinity of the injector pump when I prime it, but I have always heard that when I have primed it after replacing the fuel filter.

This sucks, as I thought I had the problem licked.

Thanks again, Greg
