There's a lot that can cause this Kenneth. Let's start with a few questions: How long as it been since this vehicle has had a tune up? New fuel filter, plugs, wires, etc? Does it spin over a while before starting up? A fuel pump that doesn't hold pressure can do that causing the system to lose it's prime.

What exactly is it doing or not doing ?

There should be a screw or two holding the lens in on the outside of the vehicle. Take those out and pull out the lens. Besides the screws there are a couple of compressing tabs that make it a firm pull out. If those screws are not apparent then you will need to access the lens from behind in the trunk. I am sure there is a concealment panel that you will have to remove but that should just be freely sitting in place. Take that out and you can change the bulb.
