update::! ok so trying to troubleshoot this this using common sense first, i turn key on lift pump does not engage i removed the fuel lines from the lift pump and stuck a coupler inbetween them (to by pass the non working lift pump) took the lift pump into the garage and hooked 12v power to it, nothing dead so yes the lift pump is shot... now moving on to stock injection pump, as i said i bypassed the lift pump hoping the stock injection pump (if working) would pull the fuel through the lines atleast enough to start and run. I dropped the fuel filter and topped it off and spun it back on, hit the primer a couple times .....truck fired and sat there at idle let it idle for about 60 seconds jumped it it reved it up a bit went back to idle then acted like it was running out of fuel again and stalled. at first i thought YES ok the stock injection pump is ok.... now the only thing i know for sure is the lift pump is shot, can anybody pitch in here with some input?
