Then I put everything back together (put the radio back into its slot, screwed the screws back in and put the front panel back on and rehooked the battery cable. Their is nothing. NO Power, No lights, Everything is shut down. Please help. Eric

I just built a factory amplifier/crossover bypass adapter for my 2002 Chevy Tahoe Z71 (non-Bose system). This adapter will allow the full range of audio directly from your head unit to the door speakers. Without this adapter, the factory amplifier will cut out much of the bass / low frequency audio to the door speakers. This adapter will continue to provide an audio signal to the factory amplifier for the rear factory subwoofer and cargo area pillar speakers.
I have posted an article with complete set of step-by-step instructions and detailed photos of the build and installation process.
The article also includes direct links to the exact parts that I purchased on Amazon to build this bypass adapter.
This is what the end result looks like. It is a 100% non-destructive adapter than can be installed or removed from the Tahoe at any time. It just plugs in between the factory wiring harness and the factory amplifier.
sometimes the vacuum line going to the actuator cracks.this will cause the diaphram in the actuator to not depress fully. you should be able to press in the diaphram by hand easily,if you cant,then the actuator is bad...usually due to debri getting into it,or from non use.
I have had the EXACT same problem with my 03 Chevy Tahoe!!! I have yet to find out the solution!? I cleaned all my grounds and changed my rear speed sensor along with bench tested my alternator! Have you found the problem? I would be very grateful if you could hit me back with an answer!! Thanks
Yes,there is a 13mm bolt head down at the bottom of the battery towards the firewall side.That's what holds the battery in place.Good luck, ChevRev. P.S. I would recomend that you use a set of jumper cables to maintain power to the system so you don't wipe out the radio codes,etc.Clamp the neg cable to the engine block & the pos cable to either the power wire on the alternator or it may have a pos cable lug near the battery.
Still sounds like a fuel problem. Try a full tank of supreme gas, plus put a can of SEAFOAM into the tank to help clean you injectors. See if this will help clear up your problem. Did you change the plugwires????
