aadilkhan Posted July 19, 2011 Report Share Posted July 19, 2011 you need to remove the upper plenum to get at it-Won't start could be a fuel or spark issue-Do below firstly you must disconnect a spark plug wire or 2 and ground it to the engine at least 3/16 away from ground -have mechanic to crank engine over. Do you have a snapping blue spark? If so then it has to be a fuel related problem. can you hear the fuel pump come on when you turn key on? If not check fuel pump fuse and fuel pump relay as they may be the second cause now check the fuel pressure to rule out the fuel filter, pump or a pressure regulator and listen to the injectors if they are pulsing or hook up. all the best.
