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...

I let a shop put it in for me because i didn't have time to and they ordered the wrong one. It goes by bed size. See how the hose hookups are the same but the floats are facing different ways. a112745b25baf90af9d6aa9e1b83457b.jpg

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.

longer beds may have a larger tank, possibly with a different pump.

then there are different emission setups, having different connections up top.

Could possibly be as simple as the stepper motor on the gauge going bad.  That generation of GM instrument panels are notorious for the stepper motors going bad.

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.

      Bent valve in 2025 GMC Canyon Denali - Requires engine swap at 14K miles

      By newdude · Posted

      No ETA is available for that engine at the moment in the GM system.   I would start at the dealer.  Try and talk to the parts manager or service manager and see if they can start a CX Connect case and get an ETA from GM on when engines may be available.  If they just check Parts Workbench and say "no eta", they aren't trying hard enough.  They need to do a CX Connect and chat with DPAC to find the ETA.

      MPG at 600 miles

      I would have to read back to get a better picture in my mind of some of the other comments and what they were using for a driving scenario they based the fuel mileage off of. That is why the fuel mileage conversation is extremely difficult to make fair comparisons from. If I was to be living in town and only driving around town, light to light and some longer stretches that doesn't have a light every block, and the usual stop at a grocery store and the bank and so on and so forth, my fuel mileage even during the summer time would be so bad with my truck I don't even want to know how bad it would be !. Then add in winter time and idling to warm it up to clear the windows and driving through snowy streets etc, large heavy trucks with gas engines have NEVER been worth crap for fuel mileage and why some little pot licker of a car with wheelbarrow tires and a 1300 cc four cylinder non turbo engine was the ticket to using a mere fraction of the fuel over a full size pickup.    By the way my truck has the 34" tires as its a HC but not the BFG KO3 tires ( that was an option for my truck but the sales guy couldn't figure out what the tires actually were so that never got on the order until it was too late to change the truck order ). So what fuel mileage your getting actually sounds good for "town driving" and with my truck when I go to town the fuel mileage keeps increasing as I get closer to town because it takes quite a while to get the driveline oils warmed up ( and why it always shows better fuel mileage on the return trip from town because its already warmed up ) but once I am in town that fuel mileage average just keeps dropping the more I mess around town and then has to recover back to something reasonable again by the time I get home for an over all average.    I'd be curious what your sticker says for the factory weight of your truck, mine is close around that 7700 lb due to the options it has. But anyway the long and short is, vehicle weight, higher rolling resistance heavy tires and a hefty driveline and a relatively large gas engine make for crap fuel mileage in stop and go scenarios, all one can do is drive it easy off the line at each stop and as my dad had said over the years, drive like a raw egg is under your foot and that's the best one can do. Years back with a carbed engine and if the carb was getting a bit out of tune etc as would the ignition system, the fuel mileage on pickups with larger engines was just awful compared to what your getting. We pay the fuel price penalty for driving HD trucks over some little vehicle, that is the reality.

      We had two Toyota’s with that engine in the mid 80s. We had 50 gallon fuel tanks, a toolbox full of tools, an air compressor and assorted parts for our equipment. We beat those up and down pipeline ROWs until we started buying diesel trucks. Then they became parts runners and first vehicles for our teenagers first cars. Our shop Forman wrecked them both two years apart when we hired him out of high school as an apprentice. Good thing he’s an excellent mechanic. It took awhile before he could be called a good driver.
