Hey guys I hope you can you please help me solve this problem? I replaced my fuel pump in october 09 i notice the fuel pump makes a loud humming sound when the car is on but there is no code??? I also notice the performance was sluggish and poor 1-2 shift. I bought the fuel pump off of ebay and it was suppose to be new and it said it was for a 97 Buick Regal GS. But one day i was going up a hill and i get P0305 cylinder 5 misfire so now i am trying to figure out if its rhe fuel pump or the 5 injector all plugs and wire have been changed coils have been tested and no problems there. So the other day i am ready to get on the express way i stop at the gas station bought some fuel injector cleaner and fueled up and when i took off everything was fine for about 10-15 min of driving and then the car started jerking when i tried to reach 60mph and P0305 came on again please help me? THANK YOU
