fuel guage empty to full
I have a 2000 Silverado Z71 with the fuel guage swinging from empty to full and all in between. I have heard of others doing this. I guess maybe its time for a new fuel module. It's been doing this for a couple of years, just keep putting it off. Is it easier to move the bed back or drop the gas tank? Also I have developed hard starting problems here lately, It having too crank extra long before it starts up. Could this be a sign the fuel pump is getting ready to go out. Any info would be greatly appreciated

Re: fuel guage empty to full
could be anything.
read codes 1st. measure fuel pressure next. this issue is discussed all over the web. some say, dropping tank is OK. many say, it is much easier to scoot truck bed back, to clear the fuel pump and sending unit. some say, 5 adults can take bed off completely. some say, it is cleaning a ground wire on sending unit harness that does it. pick your poison. I'd say, should you have that truck bed moved, do as much replacements as you can, while you there. |

The sending unit is bad and is a common problem on GMs.

if you hit the fuel tank bottom and the guage works,, this is simply a coating of film , that the fuel tank pickup has on it interferring with the current flow... my plan is to live with this until the fuel pump is replaced... also use of injector cleaner does reduce the problem ...but no cure.. |

Re: fuel guage empty to full
PULL THE BED if you change the pump!! The first four times I changed pumps on GM trucks I layed on the floor fighting with the tank and hoses and fuel line connections,etc.....The last one I decided to pull the bed and had no problems what so ever. It's just eight bolts, filler neck, ground strap and tail light harnesses. Very simple, and, it only takes two guys to move the bed off if it's a shorty. I'll never drop another one of these tanks again....

Re: fuel guage empty to full
I agree, lift the bed. When I changed my fuel pump the plan was to use my dad's engine hoist. After we got the bed unbolted, we lifted it up to see how heavy it was and didn't use the engine hoist. It's lighter than we were expecting.

Re: fuel guage empty to full
Resurrecting an old thread, I have the same issue with fuel level guage floating around, now stuck on empty with light on. Dealer says that it could be cluster or sending unit.
I'd like to rule out one vs the other myself. Does anyone know of any instructions online on how to check the voltage to the gauge cluster? TIA |
