Anyone dealt with fuel pump issues on a 2011 Chevy Malibu?

I replaced mine last year. A tip: make sure to have a friend help you lift the tank out. It’s heavy and tricky! Plus, it’s great to have an extra pair of hands.

That’s a solid tip, jacobgomez! Did you disconnect the fuel lines before removing the tank? I’ve heard that’s crucial to avoid spills.

I found the perfect guide online for step-by-step instructions. Just remember, you might need to replace the fuel filter as well while you’re at it—might as well do it all together!

Great advice! I always recommend checking YouTube for video tutorials. It really helps to see how it’s done.

Has anyone tried an aftermarket pump instead of OEM? I’ve heard mixed reviews, but I’m trying to save some bucks here!

I’ve used an aftermarket one without issues, but just do your research on brands. You might end up regretting the cheaper options.

Good point! I’d prefer to pay a little more for reliability. It’s a hassle to redo this job!

I actually went through all this too! It’s about time-consuming but rewarding. Just keep track of your bolts so you don’t lose any! :rofl:

Losing bolts is the worst, avilapaul! I used a magnetic tray for mine. It saved me so much frustration!

Speaking of frustrations, did anyone encounter any surprises during their replacement? I had to deal with a rusty connector that nearly ruined my day.

Oh no, that sounds frustrating! Patience is key—just take it one step at a time and it will eventually work out.

Reflecting on my experience, I realized that taking breaks really helped manage my stress during the process. Fuel pump replacement is a journey, not a race!

I’ve had fuel pump issues in my 2011 Malibu. A good first step is to check the fuel pressure. You need a fuel pressure gauge; it should be around 55-62 psi if the pump is working properly.

Great point! I actually borrowed a gauge and tested mine. It showed low pressure, which pointed to the pump being the culprit.

Another thing to check is the electrical connections at the pump. Corroded wires or loose connections could be the reason for low fuel pressure. Make sure they are tight and clean.

Absolutely! I found some corrosion on mine, cleaned it up, and the pump started working again. Don’t forget to inspect the relay under the rear seat too.

What are some other symptoms of fuel pump failure? I’ve noticed my car is stalling occasionally. Could this be related?

For sure! Stalling can be a sign of fuel delivery issues. Keep an eye out for sputtering during acceleration too.

I replaced my fuel pump a couple of months ago. It’s a pain, but typically, the issue is from wear and tear, especially with age. Just a heads-up!

Exactly! If the pump is making a whining noise, that could be a sign it’s failing. I had that issue too.
