Why does it not take the gas ?does this truck have fuel injection rails?
This model of Chevrolet uses a throttle body fuel injection. When you state that it does not take the gas, do you mean that the engine cranks over but will not start? If so, first take off the air filtering system and with a flashlight look down the throttle bore while someone cranks cranks over the engine. You should be able to see fuel spraying down the bore. If not, check fuel pressure. If that is ok check to see if the wires going to the throttle body injectors go on and off while cranking. You could have a fuel problem or an electrical problem.

check thefuse firstly, if this is ok pull the wires off of the switch, above your brake pedal and bridge them, if they work replace /adjust your switch. If they don't work check the circuit starting with bulbs
Why is gas comming out of my evap canister
It sounds like the fuel tank;s VENT line hose has become swapped with the SUPPLY line. Fumes from the top of the tank are supposed to be delivered to through the vent line to the evap canister, not liquid fuel. Likewise the line feeding the fuel pressure regulator and then on to the fuel injectors needs pressurized liquid fuel and not just tank fumes.
