Replying to: ebonysilverado (Oct 04, 2009 3:20 pm) Sorry, my mistake. There are 4 bolts, 1 right at the begining of the box, 1 about 24" further away, bolts 3 an 4 are behind the rear wheel.   Look carefully at the jonction of the box and the top of the frame.   Regarding the fuel gauge, unfortunatly it comes with the fuel pump as an assembly.   The only way to replace only the fuel sender unit would be to get one in a scrap yard.   The reason why your fuel gauge is acting erratically comes from the wear of the potentiometer in the fuel sending unit. The sliding contact (wiper) blades are getting inconstant reading from the semi-circular resistive element.   In simple words: you need a new one!   Stef

i figured it out the hard way but i did it   i will post pics soon...   that three bolts oversight really killed me but if found the other cause the box wouldn't budge   i will post pics   just need to know if there is a special procedure for rehooking it .. heard someone mention air in the fuel line.. is that a concern?

Replying to: ebonysilverado (Oct 07, 2009 7:27 pm) No special procedures.   Put the key to ON position, wait for the pump to stop, do this 2 or 3 times, then start your engine.   Stef

Truck will start 100 times and idle fine for about 30 seconds and then die out Replies to this message: bruce48532 (Oct 09, 2009 11:50 am) hdking57 (Oct 09, 2009 5:58 pm)

Replying to: hdking57 (Oct 09, 2009 11:24 am) did you check the fuel pressure regulator? Replies to this message: hdking57 (Oct 09, 2009 5:58 pm)

#311 of 333 how do i check power to fuel pump? by jrob4 Nov 13, 2009 (1:05 pm)

Replying to: jrob4 (Nov 13, 2009 1:05 pm) 1. disconnect the fuel line turn the key on watch the fuel pump out. 2. turn the key on listen for a wining noise from the fuel pump area.   is your fuel gauge moving erratically? when is the last time you changed your fuel filter? any pulsing/surging while driving?   the fuel pressure regulator will make hard starting

My 2000 Silverado 2500 w/6.0 sometimes has no power.Does not matter hot or cold,always starts and idles fine.Go to accelerate and will not pick up RPM.If you hold pedal steady eventually power comes back.Then will not act up until shut off again.Like I said doesn't happen all the time.Replaced fuel filter,checked fuel pressure55psi,new air filter,spark plugs the whole gammet.Cleaned MAF sensor.Anyone else with the problem and what did it take to fix.
