2001 Chevy 2500 6.0 l. engine. Went 4 miles from the house to help cut up trees from the tornado. Parked outside HQ to ask where they needed help. P-up running great, shut down normally. Tried to start it, run but die, run, die few seconds later. Ran rough what few seconds it ran, then died, numerous times. Check fuses, OK; new fuel filter (Prolly first ever) at 120,000. Well used when I got it. No difference. Pull my 2000 up beside the "01. Can't hear fuel pump in tank of "01, can hear it on '00. Mileage is about right for fuel pump to go. Owners Manual doesn't even mention having a fuel filter, much less how to change in-tank fuel pump. Have put a new fuel pump in my '89 Nissan. Question is how do I do it with this beast? Of course, I just put 30 gal. in the tank.
