The fuel pump in your 2008 Buick LaCrosse is located inside the fuel tank. Here's how you can access it:

Under the Rear Seat:

If your LaCrosse has a rear seat, you can easily access the fuel pump by removing the rear seat cushion. Look for a cover or panel under the seat. The fuel pump is usually located there.
Through the Trunk:

If your LaCrosse has an armrest in the middle of the rear seat, you'll need to go through the trunk. Remove the cover from the far back, between the back of the rear seat and the trunk space. This will give you access to the fuel pump.
Remember to disconnect the battery and follow proper safety precautions before attempting any work on the fuel pump. If you need detailed step-by-step instructions, you can refer to resources like the Buick LaCrosse repair manual or watch online tutorials.

Nothing here leads me to think it has one! A/C is controlled by the BCM.

Probably not. You can take the bolt out without removing the caliper to measure it, but you can't drive it that way.

Here is a link that will show you how to

remove the two black plugs by the hatch opening and you will see two small bolts. Remove them and the light comes out.

sounds like an issue with either your carbon filter or purge solinod being blocked
