OK so I have a 02 chevy Silverado 2500 I have had multiple issues.  I currently  have a fuel pressure  drop issues. Fuel pump , fuel pressure regulator , fuel filter is all new and sill over 4-5 hours it drops pressure. Then I have a a battery issue. New battery and alternator   and I have been jumping my battery every day after my truck sits over night .but my truck has 285000 miles on it . The gauge cluster has issues I have one gauge that is erratic and that is the oil pressure gauge then I have no back lighting so I replaced  the bulbs with blue leds and they come on for about 15 minutes then they go out . And tip would be appreciated  I don't trust dealership  or shops so I do most of my mechanic work but just can't figure this out

No dead battery problems before replacing bulbs with LEDs? If not there is your issue. You probably need to let someone else replace them and replace stepper motors. That's my .02 worth for now.

 

If you can disconnect the cluster at the back overnight then you have your answer

You say that you have a new battery. Just because its new doesn't mean that it is good. I had problems with mine. After three batteries I finally got a good one. So from now on any time I buy a battery I will be checking to make sure they are good and up to specs.

I had bought a bad alternator  from advance auto and had them replace it  then that one overcharged past 19 volts so they would not giv3 me money back or exchange it do to it being a store up north so I spent another 300 at orileys  then started having the issue .had battery check but it's good.

It's a place to start. That's why I asked. It's not a useless point. You don't give much if any real detail on what you tried or not tried.

 

So with your attitude I'll move on and you can guess the next thing to try and look into. *Hint* Been discussed plenty of times

 

have a good day

      2027 GMC Sierra: Official Discussion

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.

      Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.

      Disconnecting Battery

      By davester · Posted

      If your connector also has a big lever to get the connector on and off, you don't want to force the lever either way, as it becomes a bigger problem if you bust the lever or the mechanism it works.

      Disconnecting Battery

      By davester · Posted

      It's just useful to disconnect the battery to prevent odd shorting out when unplugging/plugging stuff together.  I also  touch the two cable ends together (after disonnecting) to drain the small amount of stored battery energy in various modules.   I believe the main system where you need to be more concerned with, so you need to do the above and then wait some time, iss when you are working on the air bag system, to prevent inadvertent firing of the air bags.   The in-cab switches are just that, plain switches, it's generally not a problem to swap them in/out.  For my '12, I'll get an error message on the dash if I power up the truck w them unplugged, but that's it (power up= turn the ignition on).   The ITBC located above the spare tire is a computer that manages the trailer brake system.  That is probably more important to have the battery disconnected.  It does have to be programmed to the truck, either before or after it's installed, for it to work.  For my '12, I had a very hard time reinstalling the main connector to it (IDK if yours is the same or not), it turned out the silicon seal was jamming up, preventing it from going on all the way.  I finally got it fully installed by lubing the seal with a bit of dielectric grease, then it slid on and latched in place easily.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      JR ! I just got the truck back from the Dealership today . The technician did a cold remote start on the truck this morning and it made the noise . It was determined that it was a starter issue and replaced it under warranty . Of course   it did not make the sound after a new starter was put in because the truck was not cold . We will we see what happens tomorrow morning when I start the truck cold  . Keep tuned !   Oh I found a video on YouTube of a cold start and it did the same thing your truck and mine do , I will see if I can find it and post it up
