When I turn the key the fuel pump is loud, it's almost like a screech (but not metal on metal) then it'll run fine. Does this mean my fuel pump is going out? Then as I'm driving when I let off the gas it makes a noise like the gear keeps spinning. It'sa 1.8 turbo with an intake and a body kit. Could that be an aftermarket part? It seems to stop after it warms up alittle bit. Any advice or directions will be very helpfull. Thax to any responders....
