Is it difficult to replace a fuel pump on 99 Chevy Malibu?

Replacing a fuel pump on a 1999 Chevy Malibu is considered a moderately difficult job, not something a complete novice should attempt without some mechanical experience. It's not a simple bolt-on, and involves several steps that can be challenging:

* Access: Getting to the fuel pump requires dropping the fuel tank, which can be labor-intensive and require special tools. This often involves disconnecting fuel lines, electrical connectors, and possibly even the exhaust system (depending on the specific model and modifications).

* Safety: Working with fuel involves significant safety risks. You'll need to depressurize the fuel system and take precautions to avoid sparks or flames.

* Special Tools: You'll likely need a fuel pump removal tool, as well as various sockets, wrenches, and possibly a fuel line disconnect tool.

* Knowledge: Understanding fuel system components and proper procedures is crucial to avoid leaks or damage to other parts of the fuel system.

While there are plenty of online tutorials and repair manuals available, if you lack mechanical experience, it's generally recommended to have a professional mechanic perform this repair. The potential cost savings might not outweigh the risk of causing more damage or creating a safety hazard if you're not comfortable with the process.
