2005 silverado 1500 fuel gauge not working


Recommended Posts

my fuel gauge on my 2005 silverado is not working. i replaced the fuel pump with one i got at 1A auto, but the gauge still does not work. sometimes it is stuck at E, other times it is stuck at F. the pump i got from 1A is supposedly the right one for my 2005 silverado 1500 rwd 5.3L ... anybody have any suggestions for me? i've seen some references to 'bad ground wire' in other forums, but nobody gives any details on what wire/connection/location, how to find/fix, etc. ... adv-thanks-ance.

Mine did that and the fuel pump was the wrong one resulting in the float resting on the side of the tank. I would pull the fuel pump back out and see if when you move the fuel gauge float arm it might be in the position to hit the side of the tank. Line up the pump like you would hook the lines up while holding it above the tank.

hmm... problem is that the new pump looks exactly like the old pump, and there is no way to install the float arm the wrong way and you can only install the pump in one position for the fuel lines and electrical connections. you say "the fuel pump was the wrong one" ... where did you get the right one, and did it look obviously different than the bad one when you got it? thanks for the reply...

in that pic, i take it the one with the black float is the correct one?

 

bed size?? what the heck would that have to do with the fuel pump? my truck is a crew cab, with what i guess is the normal size bed for that truck.

Did you find the solution to this problem?

Why would you think whatever specific problem that the o.p's truck had, is the same that yours has?

You need to diagnose what's wrong with your truck.

sure you do.  But I understand it, it takes time and effort to diagnose, it's so much easier to throw parts at the truck.  You just want someone to tell you what part they needed for their truck, so you can throw it at yours.
