I can drive it around fine and it idles fine but once I turn it off it will not start. cranks fastbut no start. I can hear the pump going and when it starts cranking I can hear the pump stop. but it starts pumping agin while the car is running. so far ive replaced the fuel filter and completely rebuilt the throttle body.. while the body deff did need rebuild it still doing the same thing. is there something that is supposed to splash fuel into the body when start??? help a rider out please  |
I would install a test pressure gauge. The fuel pump has a check valve which could be leaking bleeding all the pressure out of the system.
http://www.tooltopia.com/ sells a 5/16 inline check valve with two crimp washers for connection if you don't want to replace the fuel pump.
search check valve they have both a 3/8 and 5/16
