Did you recently change something on your setup?

what happen was, my fuel line broke, and i was messin behind the intake mani, but like i said, i pulled the harness out to see if it was something there, and it isnt. i dunno what todo anymore

 

Did you check grounds? Look over the wires that you moved, or check the fuel pump ground?
