Why does my keyless entry only work sometimes on my 2005 trailblazer? Why does my gas guage read empty most of the time but if it doesn't say empty most it will say is 1/4 of a tank? Why did all my sensors go bad at the same time?

I would start by checking for a bad or weak ground and then move to the body control module (BCM).

Also make sure your battery is in good shape with clean terminals.
