trying to trace my injector harness ground,not sure where it starts or stops or what color it is.i get pressure to rail,but no gas to plugs after trying to start it.ive replaced control module,pressure regulator,fuel pump,bypassed inertia switch,can hear all my relays kick on and off with the key.

it will start once in awhile,but when you shut it off....will not start back up for about 2 days.
