While the engine is running unplug one of the problem injectors, u can use a noid light too...it should flash while the engines running...if u cant get a noid light check each wire for continuity to ground with the engine running, the ground should pulse if its normal if its solid then we have an issue
Expert:  jrloar replied 1 year ago.
Do you have an extra injector? If so hook the injector to the harness and hold it inside of a container that will allow you to see the tip of it. then start the engine. It should squirt fuel in pulses.... Let me know if it is continues or in pulses....

Expert:  greasemonkey2386 replied 1 year ago.
sounds like you have a short in the injector driver circuit and 2 fried injectors, according to the firing diagram your vehicle has a pulsed power injector system and not a pulsed ground, did you swap in known good injectors and computer at the same time?
