FOB won't work on Chevy Avalanche
Doesn't use a fuse , ues a circuit breaker . These very rarely go bad .The right rear door works ? Uses same circuit breaker as front passenger door. The power windows an locks on your vehicle are controlled by electronic control modules . FPDM - front passenger door module , I would look for a broken orange wire inside the flex boot from the body to the front right passenger door . This is power supply to the passenger door module . Do you know what wiring diagrams are ? Free here http://www.bbbind.com/free-tsb

2003 Chevy Avalanche won't start (incorrect gear indicator)
The instrument panel cluster (IPC) displays the selected gear position as determined by the powertrain control module (PCM). The IPC receives a class 2 message from the PCM indicating the gear position. The PRNDL display blanks if:
• The PCM detects a malfunction in the transmission range switch circuit.
• The IPC receives a class 2 message indicating the park position and the column park switch indicates a position other than park, open input.
• The IPC detects a loss of class 2 communications with the PCM.
Could be the transmission range sensor . Testing would need to be done , hooking up a scan tool ! Doing electrical testing etc...

Car will not crank over
there are no sensors on any car that would keep the starter from engaging even if the fuel tank was completely removed remove the starter and have your local oreillys or autozone bench test it if its good then you have an electrical issue could be related to your ignition switch, starter and or ignition relay or fuses check all of those
