after fitting another engine (D14A4) into my EK to replace the knackered one, when I started it it only runs on two cylinders, traced the problem to the fuel injectors on cylinders two & three as they don't seem to be working.

anyone come across this problem as I am at a loss due to the fact that there not working but the other two are

cheers, Ross

 

First off hook those two injector plugs up to a noid light. If the known good noid light doesnt flash then check voltage on the hot side of the injector clip (remember there is constant voltage going to the injectors, the PCM/ECU ground the ground side of the injector) and then ohm the ground side of the injector plug back to the PCM. If all wires check out good more than likely your quad driver that powers the injectors inside of the PCM is fried.

 

I had the same problem once, i just put a couple inectors of another of the same motor, its been good ever since.
