    Key not detected

    Hello all, I have a 1999 GMC Yukon SLT 5.7L 4x4 that will not start, every light except the security light comes on the dash. When I turn the key to on I can hear the fuel pump run, it will crank and run for about half a second. When my buddy hooked up his snap on scan tool we found that it said...

    Chevy Tahoe SS 1996

    Hi All, I found a 1996 Chevy SS truck with a 7.4L engine. The owner claims it’s original and that it’s slightly longer than the regular Tahoe. Is this real? The first time I saw the Tahoe SS, I thought the Tahoe and Yukon two-door models only had the 350 engine and diesel options.

    Power Seat Track Swap Compatibility

    I recently ordered a replacement power seat track for the driver's seat in the '97 C1500 Silverado. Upon removing the driver's seat and the power seat track assembly, I have realized that I might not be able to install the new one (at least not as a direct swap). The replacement was pulled...
