I have a 1997 Sierra and the fuel pump (I think) is buzzing. Changed the filter but noise is still there. Has anyone had this? Do I have to change it?

How long has it been buzzing?

Did it just start buzzing?

Is it running ok?

If not...What is your fuel pressure?

 

The one on my 99 did it from day 1 and was STILL doing it when I got rid of it in Nov 2006.

Almost 250,000 miles later.

 

The one on my 2006 is real quite. So far. :thumbs:

I just got the truck so I don't know how long. Runs great though. I have read that some just buzz and that's the way it is. I think I'll just drive it and if it goes it goes.

Don't worry about it. Mine did that from the day I bought it new.

 

Finally quit at 97K.

I would worry a little...mine "buzzed" for quite some time; unfortunately it quit buzzing at a stop sign just before I crossed a very busy four-lane road. Your choice but I would replace.

Normal till it quits,then you know it needs a pump because now you cannot start your truck....Depends on the mileage once you cross the 100k on the original pump IMHO your on borrowed time,another thing to consider is are you the type that runs on empty or under 1/4 full tanks of fuel if so running it low on fuel constantly will have a tendency to overheat the pump,many people fail to realize that the fuel actually helps cool the pump and provides much needed lubrication for the in tank fuel pump modules,when I get to a 1/4 tank, time to fill up never go below a 1/4 tank unless it can be helped,this will extend the life of the fuel pump module for sure.Keep your pump submerged in fuel.

some guys say it is OK to let the fuel pump buzz and squeal... to me anything mechanical with turning parts should run pretty quiet... to me the noise indicates that something will be wearing out faster than it should.....

 

I had my fuel pump replaced this year because the fuel pressure got to be too low... and the new replacement one made noise from first day.... the mechanic told me to wait a couple of weeks and if it still made noise he would replace it on warranty... which he eventually did do at no extra cost.

 

If you just got the truck this year like you said in an earlier post then it is likely that the previous owner replaced the fuel pump with one that is noisy and now you have inherited it...... for best luck with fuel pumps for your Chevy truck get a OE Delco or a Delphi pump.... mine was replaced with an Airtex, but at least the mechanic stood behind the warranty for mine.

My 13 year old 1500's pump buzzed every single time I turned the key except this one time... then I had to replace the pump. The new one buzzes just the same as the old.

I guess I'm even more obsessed cause I don't let mine get below 1/2 a tank if I can help it.

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...

      Different requirements for oil filters?

      By glenn27 · Posted

      // Thank you, also for your  response. More information is always good. This 2013 GMC is most likely my 'forever truck"-I'm 77 and retired...and truck only has 42K on it-very clean-so I try to keep it that way.  Tks again for your  response- glenn

      Alternate wiring for Kicker sub with Bose system. (DO THIS)

      By smooth68 · Posted

      I started my install this weekend. Everything was pretty straight forward but I ran into one issue with running power through the firewall. The nipple grommet on my High Country already has a small harness running through it - has anyone else ran into this issue? And on the engine bay side, does the wire basically just penetrate the factory wiring boot? I did this on my '22 Trail Boss and it seems much easier but thats been a few years. My other thought would be possibly drilling a new hole adding a rubber grommet just to the lower left of the factory hole. Thoughts?   Has anyone used a T-harness off the Bose amp and obtained power from there? It seems a little odd that such a small amp needs 3 power leads

      By glenn27 · Posted

      ///// Ok--Thanks for that info--I could not find yesterday when I looked for the specs on that NAPA filter what I wanted. Their website is not very user friendly. I buy all teh filters for  our three vehicles once or twice a year. Have always run NAPA Gold on everything I own....I buy it thru my Son's account for his business-which he has a Heavy Equipment repair shop-one reason he uses NAPA so much-they have such a full line of coverage for just about anything/anywhere- He gets s  good discount because of volume bought. Anyway-Thank you -Sir for your response.   glenn
