HELP! My 1999 Yukon has a fuel guage that shakes? I have replaced the sending unit in the tank and check the ground connection (new connector) and I still have a wonky guage??? I have the guage cluster pulled and will be searching the local auto salvages for another. Has anyone seen this before? How did ya fix it??

 

Thanks in Advance

Very true, but ussually the gauge will sit and shake back and forth, sometimes fast, sometimes not at all. My oil press' motor went bad on mine and it would shake like crazy sittin' at a red like.

The guage does shake back and forth like an electrical problem .... I assume the stepper motor can be replaced? I have the cluster out and apart but I can't see how to get the guage front off from the circuit board? No screws or clips to be seen??

That was a stupid question, but I was hopeing you'd say no. On mine, which is a NBS(don't hurt me MATT) all I had to do was take the black plastic cover off the back, then lift the circuit board, turn the stepper motor and out it came. But, you'll have to pop the needle off with a fork, no need to mark its position if it's already a little shaky. Then once the mottor is all in, and everything but the needle is on, hook the cluster up, turn truck to run and push the needle on over the 0 position as that's where it sits when it's off.

Just picked up a used guage cluster at the auto salvage installing it after work today. I will let you know if your theories are correct?

Nope! No Volt Guage movement .... What's the chances of getting a bad used cluster with the same problem? Pretty SLIM I would think?

I have a similar problem that started about a year ago ('99 OBS K1500 P/U). I've read about others having the same problem, so it's probably fairly common. My friend has the same issue in his 2001 Silverado. I haven't replaced anything because I've yet to find anyone with a definitive solution. Here's a video of what mine is doing:

      2018 Silverado Console USB Port Not Working

      By Tbhats2130 · Posted

      My centre console USB ports haven’t been working and the one in the glovebox is starting to act up. When I plug my phone into the cord the radio will go black and stop playing, and the CarPlay is inconsistent.   I checked the fuses and they were fine. I changed the USB port out and still nothing. Hoping for some advice on what I should be looking at.

      The truck is a 1995 Chevrolet S10 Blazer, 4.3 VIN "W" engine. :cracks knuckles:   On a whim - because I needed a headache - this truck was for sale so I stopped to take a look. Doesn't run. Well, it does, but barely. Long crank, choppy idle, bad misfire(s), it REEKS of fuel. I can DO this..I'm thinking. Diamond in the rough. One owner until last year. A young guy is selling it, he bought it 6 months ago. It stranded him more than once, he's got a newborn. It was in the shop 10 days ago and he "thinks" they said it needs a new fuel injection system. He can't put any more money into it, needs it gone. I was thinking of upgrading my Macbook, which is a total want, not a need. For less than the price of a new laptop I can have fun for months tinkering on this truck and enjoying it. I'm taking this truck home. The guy was beyond thrilled, his wife was there, she thanked me profusely, I could tell they were hurting. They seemed like good people in a bind.   Some parts, a wash, maybe a set of tires, and I can have a few months of fun and then turn it for beer money (or the next project).   Sure enough, there's a work order from a shop last week in the INCHES of paperwork on this truck dating back to when the first owner bought it. They put a new distributor in it, fuel injection work describes basically opening the plenum and putting it back together. He said he couldn't afford any more work so he had them button it up and that's when he put it up for sale.   I'm not well versed in 4.3. I did discover 1995 uses the 1992-1995 SCPI "Spider" injector which is riddled with issues from splitting lines, clogged or cracked poppet valves and plastic spider legs that crumble over time. Cool. I'll just order me a ne---. Oh, the auto parts store doesn't have it? Rock Auto doesn't have it. eBay? $$$$$$ for used. These are UNAVAILABLE period end of story unless you know "a guy" who's still got one in a box somewhere.   Can't upgrade to the '96-'04 injector, it's a different plenum, wiring/pinout and sensor config.   There are a few kinda "know a guy" -guy rebuild services for these injectors out there for about $350. Okay, Okay... I'd like to know if anyone has used them? Anyone got a lead on these crappy 92-95 spiders?   I also don't want to send MY spider to Narnia and back without knowing if that's truly the problem. I guess I'll need to pull apart the plenum and do some digging.   I was also thrown for a loop. This 1995 model year truck has an OBD-II connector. The interface is decidedly not OBD-II. I can read and reset trouble codes and view live data, but there's not a lot of data. Like misfire count and on what cylinder, that's not there. It's OBD-1.5.   Nothing is ever easy. Now it makes sense why this guy wanted to disappear this thing for cheap. I'm guessing the shop told him the injector is toast, the part is unobtainable and they're not going to sort sending the thing to a rando offering rebuild service on craigslist, and the kid likely can't be without a working car for 3 weeks even if they'd facilitate that.   Experience with these early SCPI's? Stories? Things to check? Sympathy? (..Nah...)   This can sit until I sort it. But I haven't had a problem with a vehicle I couldn't easily solve in a long time.

      I have four that read by the dash 8 to 10% better than miles/pump calculations and I have one that is spot on.
