    consider doing electrical testing? I would guess some power or ground wire/connection has a problem. alldata.com has wiring diagrams, connector pinouts and diagnostic procedures you can use to find where the problem is.

    can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?
  3. davester
    are there any codes? with lots of rust, perhaps disconnect/clean both sides of the connection/examine cable ends (the wires) for corrosion going into the sheath & replace if necessary/reconnect ALL the power AND ground cables between the battery, engine, frame, cab, fuse box and starter charm.li (website) has a no-start diagnostic procedure you can work through to get it working.

    I would expect that to be lift-kit dependent. If the kit has interference issues w stock wheels, then the kit/manufacturer should indicate that somewhere.
  5. davester
    You mean besides the obvious, that the dfm lifters aren't using any oil to enable/disable them (they stay enabled, and behave like a conventional hydraulic lifter).
  6. davester
    ? You don't NEED to install new wheels or tires after installing a lift kit. People install lift kits in order to run larger wheels/tires, and then may need to get wheels with different offsets for these larger tires, so they don't rub.

    not all plugs will be used. gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is). But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

    computer pulses the injectors by connecting them to ground (at least on the trucks), so they get constant power...

    Different monitors do their test only under conditions specific to that monitor. you MIGHT find the drive cycle conditions for the monitor that isn't ready on this site: https://lemon-manuals.la/ If it's not there, then it should be on alldata.com for your truck, but it requires a paid subscription. And you need to know which specific monitor isn't ready.

    No, you still have DFM. GM isn't shipping some w/o DFM. You have latched onto some internet BS.
  11. davester
    Sure, but you can add all the physical stuff, wiring, switches, computer, relay, etc, the thing that stops it is the programming.
  12. davester
    No, because GM still doesn't sell the programming update that allows it to work for trucks that didn't come with it from the factory.

    There are no stickers in your glovebox?
  14. davester
    Look at the numbers on the stickers in the door jam...

    google "bathub failure curve". Basically, any part of the vehicle can fail at any time. It starts off as being more likely (early failure), then the failure rate goes down (but does not go to zero), then it goes up over time because it wears/ages out.
  16. davester
    you might read through the info on gmupfitter.com for your truck, to find a good power source.

    read your owners manual. there's only a few specific modes where recirculation can be turned on, and it automatically switches to fresh air if you change to the hvac to a mode that doesn't support it.
  18. davester
    And there aren't any "bellows". There are solid plastic doors the actuators move, which largely seal just by themselves, and then have a strip of foam around the edge to better seal the door. The foam does deteriorate over time, but this is unlikely to be a significant cause of the problem.
  19. davester
    are the heater controls set for hot or cold air? If it's set for hot, and say, to get air from outside the cab (vs recirculated air), even w the fan off, air will get pushed through the hvac system, over the heater core and into the cab. Switching it to cold will reduce the temp to whatever it is outside. Switching to recirculate mode (which may mean switching to vents or whatever, read your owners manual), will reduce the amount of airflow through the hvac system.
  20. davester
    It would depend on what you do to lower it.
  21. davester
    I would say the main negative would be that I believe it's around when the 8-speed was introduced, so most likely it will have the original parts, whereas newer trucks will have 8 speeds with various upgraded/improved parts that fixed various issues with it.
  22. davester
    ? I would expect there to be a bushing for the yoke to ride on, there is for both my '04 and my '12. Perhaps that bushing needs to be replaced? It is possible to replace it w/o pulling the TC (at least for my trucks), but it does require special tooling.

    your body automatically makes more blood for free so it's NBD...
  24. davester
    So he wants to take a 20% cut of the value of all the oil and whatever products pass through the strait? That would bump up the price of oil noticeably...
  25. davester
    You might find the specs on https://lemon-manuals.la/ or subscribe to alldata.com for your truck.
