Fuel injector problems, need advice on diagnosing problem h22
Hey all,
I just finished my h22eg install. the cars running rough checked the normal stuff and found that the #4 plug is not carbed at all. so I disconnected the spark plug wire turned it over a few times and then pulled the plug again, and no fuel on it. So I figure its the injector not spraying. so far I've checked the resistance its good at 2.3 ohms, and tested the signal wire from the ecu and its not a constant value, but it is showing a fluctuation in dc volts. what should I be testing for? whats the next step. I do have the resistor box hooked up, but have not verified (again, that everything is hooked up properly) figured if the other 3 are working then its most likely the injector.
thanks in advance.
