I have noticed occasionally when i turn off my car it will make this groaning type noise in the rear. Sometimes i worry about my fuel pump just because im paranoid and i frequently drive my car with less than a quarter of a tank of gas. But the groaning sound sounds like a little compressor or something, it stops within a minute of the car turning off though.
Just being cautious...i dont want it failing on me.
Also, i get this hissing from under the car on cold start ups, not sure if that is fuel pump related either.

 

Mine does the same thing, my friend told me that most cars do that...not sure what it is, just something that happens maybe?

 

I had a similar sound SOunded like it was comming from under the rear seat. It ended up being the fuel pump. Mine went out while I was driving and it felt like the car was being choked to death. My friend had the same sound and has never had a problem. All I can figure is the pump is decompressing.

 

Yeah under the rear seat. I had a feeling that was what it was, I just didn't know if it was normal. I guess it kinda is normal? Either way I'm still paranoid since I'm at 140k and drive a lot...

 

My pump went out at about 130000. I installed a new pump and no more noise. I think it just has to do with age and the seals.

 

How hard is it to change the fuel pump --- 4th Gen.

 

Very Easy.

Back seat clips out, Vaccum cleaner to vaccum the debris around the tank, 3 or 4 10mm bolts to take the cap off. take lines off, pull sending unit very carfully, unclip the pump and screan, reinstall.

The noise is normal...has done it since the car was new. got almost 140K on it now and it sounds the same. My neighbor's Max made the same noise.

 

is there a fuse to pull for the fuel pump or what?

 

If your changing it just pull the battary

It could be the power steering. I am having a problem with it moaning all the time though.
