    I replaced my 03 lm7 flex fuel with and 01 lm7 glex fuel. Plug and play. Of course while it was out I replaced every gasket and seal.

    Intermittent No Crank No Start

    Sounds like your on the right track. For my ground strap I left it alone and I found another bolt on the back of the engine and grounded it to the firewall.

    Intermittent No Crank No Start

    Agree with the above comment about the engine ground strap on top near the firewall. Those can corrode and break. I would check voltage from block to positive battery. Consider big 3/4 upgrade.

    Motor Oil Brand vs Consumption?

    Just curious but I didn’t see what year the engine was but have you replaced the driver side valve cover, the original design clogged easily. Also I would second the idea of a catch can.

    Post Burb Avalanche, recommendations

    Ive been looking at the 2009, mostly because I would like the newest one I can get with a 6.0. But with that said Inwould consider an older model with a 6l if one came available at a better price. Iam also not familiar with thw 6l80 E trans that came in 2009, wonder how these compare with the...

    Chevy Tahoe p0443

    The parts all work together to form the evap system. So if one part is malfunctioning the others parts can’t function as intended. Last time I was in your shoes with my 02 burb I replaced all the main components, including the vapor canister that was twenty years old. I wanted to start fresh and...

    2007 GMC Denali

    This is the second reply post I’ve seen where a supporting member squashes the OP question. The only reason we have posts to go back and reread is because people post questions and other try and answer them. There’s really no such thing as a new question. So should we all just reread old posts...

    2020 Tahoe LT, wire tap or fuse box?

    I agree with blainebug. I recently added LED running lights to my step boards and tapped into the running lights and signal lights without a fuse. The circuit is already fuse protected.

    2001 Tahoe brake light issue

    And you are sure that the brake bulbs are on as if depressing the brake or are they the bulbs that illuminate when the headlights are turned on for night driving?

    How to clean fuel injectors ?

    If theres larger debris inside the injectors, or build up of gunk then no amount cleaner you run through is going to do a very good job. The larger debris just cant get through the small injector holes.

    Removing Rear Coil Springs

    You just need big jack stands, the small ones wont give you enough height to be able to remove the springs. While youat it replace the OG shocks, theres a kit on Rock auto where you can get aftermarket springs and shocks so you dont have to get the expensive factory replacement. NVMD looks like...

    How to clean fuel injectors ?

    Pulling the fuel rails is not a hard job really, look for and clean out the clogged injectors, and install new o rings. Ive seen some videos on youtube where guys will hook up a 9v battery and get them to open and spray cleaner through them.
