Ihave an 01 Tahoe 5.3. I went st start up to go somewhwere and she wouldnt start. Would kind of start but immediatly die. Tried several times and let it sit for awhile. Trued again and she started right up. Now my security light is on. Ok i lied. The security light went off just now. I am pretty sure the factiry alarm is the issue. Can someine shed some light on this system and if i can reset this light? I also noticed that my buzzer does not come in when i turn on the key.
