Well the wife called me yesterday at lunch after the 97 Burb went down

 

She was running errands and it wouldn't restart. I got there and checked for fuel pump noise.. nothing..

I played the shell game with the fuel pump relay.. nada

 

I beat on the tank with a BFH.. zip

 

I pronounced the fuel pump dead at 12:35 CST :banghead:

 

I priced a new pump and strainer for under a c-note and was going to tow it home and call a few buddies, one with a tranny jack.

Then I remembered I had just topped off the 42 gallon fuel tank on Monday :crackup:

 

with 300 pounds of fuel not counting the empty tank weight and just a driveway..I wussed out and took it to my friend's shop... he is charging me $135 labor and I bought the parts..

 

I normally do all of my repairs...but I wussed out on this one because of the lack of a tranny jack and shear weight of the fuel...

Yeah, I think the '97's were some of the last ones you could just buy the pump and strainer seperatley without the module for the sender...

I think that may have changed in '99.

 

 

 

 

I can't help but wonder what the reasoning behind this was.

 

I just had my gauge and pump assembly out (I was able to fix the gauge problem) and it looked like a standard GM fuel pump, although the feed pipe may have been glued or otherwise affixed to the pump outlet. Same electrical connection as well.

 

I did notice that there is at least one company making replacements (the entire assembly), but I couldn't find a listing for just the pump anywhere.

 

Maybe that's one reason GM didn't do anything about the fuel gauge problem - they figured the fuel pumps would die and that requires a replacement sender as part of the package, so the problem gets fixed by attrition.

You're lucky I replaced 2 pumps on my 96 Sierra before it even got to 100k miles. You never know when the freakin things are gonna just die on you!

My buddy had like 4 or 5 (lost count) replaced on his 96 chevy before the last shop came to realize that the sending unit was shorting out causing the mishaps.

 

My 99 just started to get noisy last winter, so I am waiting for that one to possibly go.

You have to worry when it isn't noisy :banghead:

 

My 2000 had the fuel pump whine since I bought it.

I feel like replacing mine just so it won't die out on me while I'm driving. I've had that happen once to me in a different car. But I'm going to lift the bed out instead of dropping the tank. I'm wondering if I should get a GM pump or aftermarket one...

I had the same idea on mine.

 

Where I checked (rockauto) the aftermarket (airtex) was pretty much the same price as the acdelco. I didn't price direct from gm.

It wouldn't suprise me if the pump you buy at the auto parts store is the very same that you buy at the dealership

I have over 100,000 miles on the original fuel pump. so far so good, if it holds up till next spring I'll replace it myself but if It goes before then I will just have to take it to the shop to get replaced. As I have gottem older I do not like to do any work on the truck myself during the winter time .

When I had my '98 1/2 ton, the first one went out at around 80,000 and the second went at about 110,000. Got rid of it 2 years ago and it had almost 118,000 on it. The guy who bought it has put 60,000 on it since and not a problem. My dad's '98 has a little over 140,000 and is still on the original. I wish I had his luck!!!

:banghead: My 1998 reg cab short bed Z71 pump went bad around 120,000. my 2002 HD has 130,000 and hasnt gone yet. The pump for the 98 was like 300 bucks. Looks like I got ripped.

 

Oh, and I pulled the bed off my 98, it was SOOOOOOOOOOOO much easier than dropping the tank.

I replaced the fuel pump on my '99 at 110,000 miles. I had the dealer do it and it was....(gulp), $640.00. It seems the pumps on the nbs trucks have the sender unit intergrated with the pump.

 

My pump never actually stopped, but at times the truck wouldn't fire up right away. When it did that, I'd release the starter for a couple of seconds, and crank it again then it would fire right up. I thought it was the pressure reguator - nope, it was the pump. I know it seems like a lot of money, but I'd rather pay that then be stuck in the middle of the desert on the way to the river with at boat in tow. :banghead:

      Help purchasing a touch screen digitizer

      By mark249 · Posted

      Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?

      I have both but typically use the 4 legged walker (wheels on front, ski's on back).   The four wheeler is starting to be used on "longer" outdoor walks.  The 4 legged walker is particularly helpful in practicing good walking posture.  Both of my knees are at different stages of recovery and I'm trying to not develop poor habits.  I can actually manage with a cane but it's very difficult not to favor one leg over the other.  My PT recommends I continue with my 4 legged walker for a while.  Yesterday was four weeks since my last knee replacement and I'm excited about my progress to date.  It has been a hell of a rough journey so far but it is exciting to witness  systematic and continuous improvement.  I went for years watching the decline of my "mobility".  It seems that everyday now I am alerting my wife to something I can do now that I couldn't a day or two ago!  I encourage anyone facing the prospect of knee replacement to share any concerns with others who have had the surgery.  It isn't an instant fix but rather is a considerable amount of short term pain for long term gain.  Recovery time and pain levels vary for individuals post surgery but the end results are typically very positive and I've never encountered anyone regretting having had the surgery.

      The lifter issue can be dealt with by shorter oil changes and quality oil IMO.

      Wiring Help, Please

      By Core-Lokt · Posted

      I'm putting in an A-pillar pod/gauges, and I'm asking if anybody can identify a (preferably) fuse for a switched power and illumination circuit on the driver's side interior fuse panel. Offhand, everything I checked with a test light was constant-hot, and I'd much rather uses a piggyback fuse. I can certainly find a wire, but I'd rather not half-tap.   Thanks in advance for any help.
