    Starts and immediately dies....

    The only time it flashed is when it would start and shut off after 1-2 seconds. Prior to resistor the light would randomly turn on and pff while.driving. Perhaps I'll look into a replacement BCM.

    Starts and immediately dies....

    Thanks for the explanation. Thats what ive read too. I have utilized the 2.2k Ohm resistor method. It does start as it should, however the Passlock light stays in all the time. In might try to check the resistance and use appropriate resistor like the South Main Auto video or just send the...

    Thanks for conformation. I was looking here to bypass the Passlock/VATS. http://www.bergerweb.net/PasslockFix/ Looks like i can also send my PCM to Black Bear https://www.blackbearperformance.com/blogs/articles/how-to-disable-the-gm-passlock-system Also South Main Auto has a video

    Starts and immediately dies....

    My 2003 5.3 flex fuel with 333,300 miles has recently had Pass Lock security light turn on randomly while driving. It does not affect the engine at all. There have also been some other electrical issues lately. The drivers seat does not move nor does the horn function now, All fuses passed with...

    What's a good year? Or one to avoid?

    Why? Those fans electric fans will not outlast a hydraulic fan clutch. As other said, look for Hydro boost brakes. I don't have it and mine were down right scary until i upgraded to NNBS brakes. Also steering wheel radio controls were only available 03-06. If younused them before, you don't...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Replace the rear wheel bearings and seals on both sides even though one seal was bad. I figured it was time at 315 k. One of the bearings exploded while I was using the slide hammer it was a little tricky to get out after that. That same side had some pitting axle shaft. Nobody around me had...

    Rusty Fuel Line and Filter

    Thanks guys. I've had this truck for 5 years or so. I can't believe ive never replaced it. Esp at 312k miles now. It runs great, just noticed a slight delay on cold starting recently. I have the PO's records and the pump has been replaced at one point years ago. For the naysayers, the brake...

    Rusty Fuel Line and Filter

    What are the odds that i will be successful in removing and replacing my filter without destrying the lines? See picture. I've been soaking it in PB blaster a few nights in a row to prep.

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    New rear hatch struts and Toshiba HIR1 Hi beam bulbs. Also did the 4-Hi mod. Nice and bright now!!! The hatch is aluminum and the cheap Amazon ones are are waaaaay too powerful. First time i opened it, it flew up and busted my fixed rear hatch glass hinge. The Stabilus are what ours came...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Finally finished my NNBS brake upgrade. After an overnight soak with PB Blaster, the hard line to rubber hose connection freed up. Other wise i was ready to run a new line from ABS to drivers wheel well. Had to drill, tap and helicoil a control arm and both knuckles for barke hose hold downs...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Started my Big Brake upgrade with Power Stop kit (from a 2008) and new GM OEM rubber hoses. I broke 3 bolts (2 on one side and 1 one other that hold down brake hose) and drivers side hose might be permanently rusted to hard line. So i might have to repair last few inches of the hard brake line...

    Best highway tires

    Michelin LTX are the best i have ever owned. Great dry, wet and snow traction for a highway tire and super quiet. Look for take off rim swaps with low mile Michelin, that's what i did. Much cheaper and got 18" wheels too so I could do the Big Brake Upgrade.
