Dead tahoe
 

Hi all
Just parked my tahoe hybrid underground and when I came back to start it an hour later, everything works fine (all lights work in the dash board and the inside) but the engine does not even attempt to run. My wife was driving it in the last few days and I notice the gas cap was not properly close. I am wondering if this can be a possible cause. I tried to give it a boots and no suggest.

I wondering if this is a software problem and if and how I should reboot this thing? (Unplugging the battery ?). I left the truck there and I am planning to go check it Later on.

Any thoughts? Thanks in advance. JC
