My 1993 infiniti G20 is backfiring and sputtering when starting off. I just had the fuel pump out working with it and had hoses off ! Ran good before i did that ! What could i have done to cause that . Is there somewhere that i can bleed the fuel line?


The reason i had taken off

The reason i had taken off the fuel pump was the car was not getting fuel. So i took the pump out to test it. I am thinking that there is air in the line that is causing the backfiring and sputtering cause there is new plugs and wires on it and it has been timed.
