Upon a cold start i have a rattle coming from the passenger rear of the car. after it gets warm, it goes away. when i open the trunk i hear it towards the gas tank. it is not knock or a exhaust leak/rattle but more like a solenoid or relay click. im thinking its the fuel pump(stock). the sound only appeared after the turbo kit install with greddy FPR. im also assuming the fuel pump because my top end is not so great.

has anyone experienced this before? and suggestions?



aarOn.

 

nope but a walboro FP is cheap insurance.

 

That makes no since to me at all...

edit* oh... top end POWER, I was thinking top end of the motor. Now it's clear.

If you are low on top end power and it's due to lack of fuel then you have a bigger problem then a clicking in the back end.
