    LBZ HVAC Issues

    I’ve changed probably 5 Blower motor resistor between my 04 LB7 and 06 LBZ 99% of the time that’s the problem you can get them at autozone and they have lifetime warranty if it goes bad just get a free replacement. Sent from my iPhone using Tapatalk

    04 Lb7 won’t start

    Thanks for all the suggestions everyone!! I figured out the problem I ended up just pulling the pass side valve cover and found one of the O-Rings for the injector lines was messed up. I replaced that and now she’s running perfect and starts right up!! Sent from my iPhone using Tapatalk

    Ok I pressurized the return line and I can’t hear any leaks so do you think I have a stuck injector?? I’m going to check all the fuel lines to the injectors to see if one of them is loose or something. Sent from my iPhone using Tapatalk

    I checked to make sure the lift pump is working and it is so I know fuel is getting to the engine. I haven’t checked the actual fuel pressure with a gauge but after cranking it I pushed the little needle on the fuel pressure test port and I had barely any pressure. I have no visible fuel leaks...

    Lb7 Injectors

    I don’t come on here much but I would really appreciate it if any of you guys had any information about what injectors I should get for my Lb7 it has 226k on it and everything is stock as far as I know.

    LB7: Shift indicator issues

    When my 04 GMC Sierra lb7 gets cold the shift indicator on the dash doesn’t work or works on and off and when it goes off the trans temperature gauge doesn’t work. Any idea on what would cause that I changed the sensor under the dash with no fix?? Sent from my iPhone using Tapatalk
