so there is this anoying noise that when heard from the inside of the car sounds like a speaker having interference, but i had the chance to be under the car while the engine was running and i was able to track it down to where I suppose it's located the fuel pump, however it's all covered up and close to the fuel lines, it sounds like if a pump was sucking air every three or four seconds. Any idea that maybe causing the issue

 

My guess would be the vapor purge tank/system.

 

you lost me at the phrase " it's located the fuel pump". But the fuel pump is in your glove box behind the p/s seat. My guess would be a manifold vacuum leak or possibly an exhaust leak.

Vapor leaks you really do not hear that from inside the car much.

 

Guess again.

 

Guess what again? Are you implying that on a Z the fuel pump is not right under the glove box behind the passenger seat? Perhaps in the 07 and above it may or may not be moved to behind the woofer, but still.

 

Fuel pump is in the gas tank. But let's not digress....

OP indicated that he was able to get under the car with it running. That's how he isolated to the area of the fuel pump.

 

Oh i should have pointed out if no one already knew that the Fuel pump was located in the fuel tank, with the exception of it being accessed from inside the glove box for a removal and replacement, or just to check to see the "hissing" sound a tad closer and better perhaps.

my bad!

Perhaps he just hears the buzzing sound of a fuel pump starting to go bad if thats the case.

 

nevermind, I was excited about finding out the fuel pump was accessed through the glove...ha
