Default no more lift pump nois when starting up...

well today last time it stopped Beasty ive heard a strange noise comming from the engine for about 5 sec after the engine was shut down
and now when i start it it take about 10 sec before it start...i noticed that i dont hear the fuel pump priming when i turn the key to on....

its start anyway cuz my auxiliary goes on at 40psi and when i crank the engine the oil pressure goes up enough to light the pump so thats ok but im pretty sure the original lift pump is out...

what do ya think?
Yeah i know i didnt had time yet to install my fuel pressure gauge but my steerting pod isnt in yet,im waiting it since 2 weeks now

you have to bump the engine over a little for the lift pump to come on.

Check your fuel pressure at the VP44 test port. You can get a hand held gauge for about $20 at most parts houses.
