I so need it to run for work.Thanks for any help.Lonnie 904-418-2376

You could have pinched a wire going to the drivers side injectors. It is not hard to do. I would pull the upper intake and check the wiring very closely. There isn't much space back there where the harness exits with the fuel rail, intake, and distributor so close. The harness needs to exit on the bottom of the fuel rail. Also make sure the clips are holding the harness to the fuel rail. I added a couple zip ties on mine. Good luck!
