There is a noise coming from the fuel rail pump or something. Right next to the coil pack there is a tube that comes out and goes in under the motor cover. I belive that it is the fuel line or something. Is it supost to make a pulsing noise, it is pretty loud. If not what would be wrong. I replaced my ps pump and water pump last night and still have the ssssssss sound during acceleration. could that be a bad injector or something, how do you check injectors.
