So when I pulled my backseats for the system, I started to notice a high pitch whine with the car on inside the cabin. It sounds like it's coming from the fuel pump area, but I'm not sure, and I have no idea what would cause it... It's not anything related to the system like my initial thought, but I've gone through and checked everything. It does not change with speed, rpm, or anything else I can think of. Does anyone have any ideas what this high pitched screeming could be? I'm all kinds of confused and it's starting to get extremely annoying... Any thoughts are greatly appreciated...

 

Fuel pump.

 

fuel pump... i got used to it
it seems like there is another noise maybe too, something to do with the electrical system itself, cuz the noise changes when i have the turn signal on.... unless that is the power to/from the fuel pump or something

 

So is it just the fuel pump running? Nothing I can do about it to shut it up? It's really fuckin annoying...

 

Put the seat back in? That's about it.

 

I'm going to try that tomorrow morning before I go to class. I got a free door pack of Damplifier Pro from Second Skin Audio, so I think I'm going to try out some of their Luxury Liner as well. ~$110 worth of goodies for like $40? Hellz yeah...

 

Yep def sounds like the fuel pump

 

So, I put the back seats back in, and that pretty well solved it. Now I just need to get some large bolt/lock cutters to remove part of the rear seat so that the seat back will slide into place like it's supposed to... Minor modifications for the stereo. It's all worth it in the end though... Unfortunately, my voltage is acting up now, so that's not a good thing... Yet another problem I need to solve, and quickly...

 

Where is our fuel pump i have a 97 3.0 cl
