heres the story...my dumb *** boss flooded my engine when my car was running he pushed the throttle cable forward and flooded my engine a . I did the whole un flood procedure and got it running again. After I let it run for a good 20 min I turned it off and tried to restart and all i am getting is backfiring. It wants to start but it backfires like a single shotgun round. .....the fuel tank is low but would that be the problem?

 

How old are the plugs? Change them out and try again. Sometimes you can foul a old plug when you try to do the unflood stuff. I have before, maybe not everytime, but with old ones, seems like I always had to change them out afterwards.

 

plugs are brand new..i dont know whats up..i am running all ngk 9's all around..does it matter if the plugs are all trailing?

 

make sure your map sensor didnt come loose
