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.
Simplest solution is to check the belts on the front end of engine. Aquealing noise frequently comes from belts slipping. Tighten, or, if better than 60,000 miles of so, replace.
The battery is under the floor behind the passenger seat. Its under the floor pan in the second row passenger floor area.There are access points under the hood for jump starting.-----Thanks.Helpmech.
The battery is located under the hood on the left or right in
this model and the fuses box under the left hand side dash by the
driver. But it may be on the right hand side under the dash too.
