  1. 96 k1500 Won't crank Won't start

    Chevy C/K Truck Forum
    A few years ago, I posted this (https://www.gmtruckclub.com/forum/threads/how-to-test-for-a-bad-starter.141610/ ) with a link to a fairly good write up for testing a starter on the vehicle. If you are up to doing the diagnosis yourself, that should walk you through the process of testing.
  2. 1996 tahoe starts then dies

    General Chevy & GM Tech Questions
    It sounds like a fuel issue, so the next thing I would do would be to put a fuel pressure gauge on it and make sure that the pressure is 60+ psi. If the pressure is low, then it will have trouble starting. If the pressure is up where it should be, then I would be checking the injectors for a...
  3. 98 K1500 5.7 vortec - Truck starts but stalls seconds later after fuel pump replaced

    Chevy C/K Truck Forum
    I have had trouble with my '98 at 50 psi pressure. At this point, I would work on diagnosing why you have low fuel pressure. I might check my pressure gauge against a known good gauge or on a known good vehicle to make sure the pressure gauge is working correctly. On these continuously...
  4. Fuel pressure

    Chevy C/K Truck Forum
    It looks like this should be a reply to this thread: https://www.gmtruckclub.com/forum/threads/fuel-pressure.1456718/ where he says he has a '95. I believe the '95s had the TBI system, which will operate under much lower pressure (something like 2 to 5 psi or something like that). There...
  5. Impressed by gas mileage for a 2019 Suburban

    Chevy Suburban Forum (GMC Yukon XL)
    For a recent road trip, we decided to rent a car. Reserved a minivan and, as Seinfeld discovered years ago, reservations for rental cars don't mean much, so we ended up with a 2019 Suburban. All told, I'm not sure there was much that I was amazed with -- similar in most ways to my other two...

  7. Clock (and only clock) doesn't work '07 with nav system

    GM Electrical Tech
    Fixed it! Tried some different internet search terms and found out that there is a secret button for getting into the diagnostic screens, and the clock can be reset in there. Steps: 1) Display screen 2) Hold finger in lower left corner for 10 seconds or so until it comes up with a number pad 3)...
  8. Clock (and only clock) doesn't work '07 with nav system

    GM Electrical Tech
    Yes, the clock "tab" is in the upper right corner of the display. It shows a ":" only -- not numbers. When I select XM (or AM or FM or other "tab"), the clock "tab" stays in the upper right and displays ":".
  9. Clock (and only clock) doesn't work '07 with nav system

    GM Electrical Tech
    The clock on my '07 Suburban won't work. The sound system and nav system all work fine, but the clock will not do anything. The clock displays a single ":". When I bring up the "set" screen, there are no digits in the hour and minute fields to change by pressing the up/down buttons. I tried...

    Something brought this to mind today, and I notice that it has been years since this was bumped to the top.
  11. 5.3 swap into k1500 suburban

    Chevy Suburban Forum (GMC Yukon XL)
    My best guess off the top of my head -- my '98 K1500 Suburban with the 5.7 averages (winter mix of city and highway) 13 to 14 mpg. My '07 K1500 with the 5.3 (with AFM, which is supposed to boost mpg a little), according to the DIC (winter mix of city and highway) has averaged about 14.5 mpg...
  12. 2007 5.3 top end/cylinder head education -- urgent

    General Chevy & GM Tech Questions
    Update for anyone who cares. Got really tired of dealing with the long distant dealership, so I coughed up the cash to have the 'Burb shipped to a hometown dealership. They replaced the LOMA -- expecting that it would not fix the problem, but, probably for warranty reasons, they could not just...
  13. Stranded...Truck won't start

    Chevy C/K Truck Forum
    Is it tight? Sparks suggests that electricity is jumping an air gap somewhere, and smoke is indicative of excess heat from too much resistance (like the resistance from jumping an air gap). If this were mine, I would grab my 5/16 or 8 mm wrench and see if I could tighten it up enough. If it...
  14. Stranded...Truck won't start

    Chevy C/K Truck Forum
    You say you have a brand new battery, which suggests to me that it was recently replaced. I don't know if I just have bad luck with battery cables/bolts, but it seems that every time I replace the battery, I end up replacing the bolt(s) that attach the cables to the battery posts. With my...
  15. Remove 4 wheel drive from '92 K1500 suburban

    Chevy C/K Truck Forum
    Perhaps I should keep my poorly informed information to myself, but I figure the other guys will correct me where I am grossly in error. I am not certain of all of the details. Short but useless answer -- yes, I'm sure it is possible to remove the 4wd components if you want to. Yes, you can...
  16. Just a simple question about having 4 WD Tahoe vs. a 2 WD edition ?

    Chevy Tahoe Forum (GMC Yukon, Cadillac Escalade)
    Is there any advantage to 4wd? 4wd give you more "go" traction (not "stop" traction) when you need/want more "go" traction. For on-road/paved road driving, 4wd really only adds advantage if/when you encounter snow (maybe sometimes rain, if your road surfaces get extra slippery when wet). How...
  17. Can anyone help me figure this out?

    Chevy Silverado Forum (GMC Sierra)
    If we are thinking something aftermarket, in addition to the possibility of an e-locker, I thought maybe something like suspension air bags.
  18. 2007 5.3 P0121 TPS code -- maybe fixed?

    General Chevy & GM Tech Questions
    It's the same vehicle as here: https://www.gmtruckclub.com/forum/threads/2007-5-3-top-end-cylinder-head-education-urgent.1450594/ that is still waiting for me and the service center to figure out how we are going to work out the AFM stuff. Because it died on vacation and I eventually just had to...
  19. 2007 5.3 P0121 TPS code -- maybe fixed?

    General Chevy & GM Tech Questions
    It's a 2007 Suburban (LT, I think) with a 5.3 L engine. I cannot get pictures, because there are ~800 miles between me and the vehicle.
  20. 2007 5.3 P0121 TPS code -- maybe fixed?

    General Chevy & GM Tech Questions
    That's good information, Motor City Rick. When I first encountered this on my '07, I discovered that it was a "drive by wire" system, which meant that the TPS module had more than 3 wires going in. I have had trouble finding a wiring diagram and other information that would help find the right...
