ok so i have no fuel goin to any of my injectors what could it be
i tested all injectors and they all have over 11 ohms resistance
tested plugs with noid test light and all tested good
so i decided to pull my fuel rail and see exactly what was goin on and found that no gas was spraying from any injector so i put my hand over each one and could feel air pushing out, i can hear the fuel pump priming so i assume its working my only other guess would be fuel pressure regulator?????
any suggestions would really help
also i have a walboro fuel pump sr fuel filter and stock ka regulator and msd could that be the problem?? (bought the car like that by the way)
also would it matter if i still have the metal tubes that split the rubber fuel lines from the rail to the lines and fuel filter i'll take a pic if u dont know what i mean
cuz the guy that had the car before me just had straight rubber lines from the fuel rail to the filter and other fuel line???
thanx for any help
