I just had my second oil change at the dealership. I asked them to check for a hissing noise coming from under the truck. It is quite loud and worse during power up (when I turn the key "on"). They said that it is the fuel pump. I asked if they will change it, his response was "no it is still working". Truck still under warranty.
Does that make sense?
Also, when I left the dealership, there is now a louder " nock" coming out of the engine, mostly at lower RPM.
Any suggestions?
