Disconnect fuel injectors, insert noid light, and watch the end of the extension when you turn over the engine (a flashing light indicates normal pulsing voltage); If the light flashes when the engine is on, the "engine control module" or "program control module" (not car computer) is giving the injector the current to open and close and therefore the injectors are receiving the signal to open and close solenoids to inject fuel; If not, injector may be gummed up and need cleaning.
