2001 Z71 5.3 with 155,000 miles...Needing a new fuel pump. From what I have read most say go with another AC Delco pump. Anyone know the part number and the cheapest place to pick one up or order from?

 

Thanks in advance!

I'm pretty sure mine is a Delphi

 

Here's some good ones I was able to find

BTDT. Stick with AC Delco. I got mine through eBay from one of the online stores. Been running good ever since, though I am still paranoid that it's gonna happen again.

When I get the chance I'm going to get a couple of replacement pumps (not the entire assembly) since I have the previous assembly. Replace the pump and still it in the toolbox. And the next time it happens, after I have a cow and a hernia, I can try to replace it. I also plan on cutting a hole in the bed so I don't have to screw around with tilting the bed or droping the tank.

Just out of curiosity, to the posters above who have seen a fuel pump failure. How did yours go (while driving, on startup?) and did you have any warning signs beforehand?

I couldn't drive over 50 mph on the highway when mine starting going out.

Where you able to see a drop in fuel pressure? Was it making abnormal noises?

 

I'm going to proactively swap out a noisy pump on my recently purchased Suburban with 150k miles. Of course until I actually do the work I will second guess myself about spending close to $300 to replace a working part (I checked my fuel pressure last weekend and it's at 54 psi, dropping to about 50 psi after sitting for 5 minutes). Just curious about other's experiences as this does seem to be a weak point on these vehicles.

I didn't bother to check the fuel pressure since I knew it was the fuel supply by the symptoms.

 

You don't give any info about your 'burb. Even a couple of pounds off and you can experience problems.

 

Post some details about your 'burb.

I've had my 2000 Suburban 1500 LT (5.3) for about a month now. The trucks runs great and isn't showing any symptoms other than the whine from the fuel pump. I've read that this is somewhat normal for these trucks but based on the mileage I figure it probably is toward the end of it's life anyway.

Prior to 2004, there is a fuel pressure regulator under the hood, driver's side of the engine. They can go bad and cause problems. Always make the FPR the first check before replacing a pump. We've never had whiney pumps on the GMT 800s in our fleet. We usually can't hear them at all. Yours may have been replaced and probably with a aftermarket model that is noisy.

 

Your minimum pressure should be 55 psi ranging to 62 psi. Key on engine off. You may need to cycle the switch a couple of times to get the highest reading

Is there an easy way of telling if you need a fuel pump WITH or WITHOUT the EVAP emissions plug? Going to order online and just as sure as I do, the way my luck runs, i'll order it, get the bed off, and have the wrong pump...

Went through a couple failures with an S-10 and I noticed nothing went out all of the sudden at random times (would start back up after cooling) while driving down the road. I just noticed the truck got quiet and the steering got tough and thought Hey! my truck isn't running. Noticed I had more power after replacing.

or you could drive the truck and if it goes out pull the bed off and throw in a quality replacement, and most likely not have a problem for as long as you own the truck.

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

      By Atlas · Posted

      Blazer is all put back together. Another hard-won battle. The 4.3 is not easy to work on in such an archaic and narrow chassis originally designed for an inline 4.   My baffle issue is solved. I returned to the OG junkyard but was ready for a fight. The Blazer I had picked from was stacked on another vehicle so I had no idea how the heck I was going to get myself to working height to pull the front end apart. I had seen an S10 pickup on the ground so I was hoping the part would be the same, AND, I couldn't remember if the S10 still had a front end or not. But I didn't need to worry because it turned out to be my lucky day. The yard had just taken in a '98 Blazer, sitting right up front, on the ground, with room to work around it, and the front end hadn't been hit. The baffle and all the clips were factory perfect. I also scored another good handful of odds/ends and the whole shebang only cost me $20.   Got everything back together and it fired right off, sounds good, runs good. I've got a little coolant drip from a lower water pump bolt (D'OH!!). I did the right thing and snugged it down a little bit, and of course that didn't fix it. Yet again, I will have to soak everything in coolant to drain it down to the water pump, remove the bolt, and attempt to re-seal it. Nothing is easy on this truck. Nothing. But now all the radiator plastics are correct, snug, and fully functional. No more rubbing on the cooling fan. It runs, drives (took it for a 30 mile drive last night), no Check Engine lights, EGR is working, no vacuum leaks. We're getting closer...   The replacement wiper motor arrived yesterday. The tailgate was already disassembled and waiting, so I threw that in. It works! Sort of. Two new issues on the list. While the motor is strong enough and the gears aren't stripped, the wiper is hanging up on the bottom of the rear glass. This is the old style where the lower half folds down like a truck tailgate, and the glass swings up, and they meet in the middle when closed. The glass isn't sitting flush with the tailgate, now that I look at it. No rubber bumpers that I can see for adjusting, so I'll have to look at the hinge adjustment to see if I can correct it. Also, the washer/squirter just dumps fluid underneath the truck. The lines actually run inside on the floor so I'm guessing the tailgate is soaked at the rear trim and the line is disconnected. There's also a drain there....probably for this reason.   The leaky water pump bolt was really disappointing. JUST STOP LEAKING...OMG!!   Replacing the window motor and a rear door speaker are still to do, and then everything will work. I want this to feel like a "good" vehicle worthy of dropping $600 for new tires before I do. That means no leaking first. I hurt, and I'm kind of cranky, so I'll probably take a day of rest and do the water pump again tomorrow.

      Just saw on Jay Leno the new Scout. That’s the way it should be done.

      EV's have their nuances too. Best to operate the current type of lithium batteries between 20-80% charge. No real need to charge until you hit around 20%. Occasionally charge to 100% when needed. Longer term storage, battery should be 50-60%. At least those are the guidelines for our iX. We've been exceptionally good to the battery in that car...easy to do when you can charge at home like we can.   EV's lack so many of the rituals and so much of the visceral feeling ICE vehicles provide, which is why I think they're hard to accept for a lot of gearheads. They're fun in different ways, though.

      We have got a lot of rain lately, we needed it. Storms/lightning took out a floor fan. Dirt roads badly rutted from run off.   Power here is sketchy, whole house surge protector in the service panel and all electronics plugged into surge protectors. My biggest concern is my stereo, I've been an audio nut for years. $25 k in equipment. Stereo is on it's own special surge protector.

      Happy Birthday!  I also turned 72 this year.  In some groups I consider myself to be a young senior and in others I realize I have serious years behind me!  In June I spent a week in the hospital due to a blood clot following knee replacement surgery.  The hospital Doctor assigned to my care specialized in Geriatric medicine!  He is a great Doctor but the fact I required this type of specialized care  made me feel old!  Aging comes with new challenges but I sure appreciate getting older!  It most definitely beats the alternative!!
