when first started it runs very rough and sounds like it is going to cut out. When I hit the gas pedal it makes it worse. Also it smells like fuel. The engine size is 4.3L

How long since a tune-up? Any applicable trouble codes? You should be able to check mil codes, yourself. Check for external gas leak. Check vacuum line to fuel pressure regulator. Check evap system.

If you suspect a fuel issue, use a gage and check fuel pressure.
