I have a 2003 Pontiac Bonneville / 120,000 and I need to replace the fuel pump. Is there an access panel under the seat or in the trunk to get to the fuel pump or do I need to drop the tank from underneith?

I drove the car for about two months with it dying randomly and starting back up with no problem. Then all of the sudden it dies in walmart parking lot and wont start back. Then engine cranks fine. Im no master mechanic but I know the basics of cars so my first thought was the fuel pump. I listened for it to kick on and it didn't. Hit it with some starting fluid and it fired up for a few seconds. So that told me it was the fuel pump. However I wanted to check the fuel pump relay and fuel pump fuse before investing in this fuel pump. Thats where I am having a problem the fuse is not labeled on FUEL or F/P and Neither is the relay. Can anybody pin point the exact location of these two. And let me say this dont know if it has anything to do with it or not but the Windows quit rolling down at the same time. Im pretty confident its the fuel pump just want to check these two things before I invest a 150$ in a fuel pump.

Lets try testing the relay use the post above. Can you hear the fuel pump come on for five seconds when you turn the key on without cranking the engine over?
