Aside from carefully inspecting the wiring to look for possible shorts, the injectors can be tested for their resistance. If I can find what the acceptable values are, I'll post them. You would need an ohmmeter to do the test and it's as simple as unplugging each injector in the affected bank and checking the resistance across the two terminals. You could check them and replace whichever of them shows a much higher resistance value than the rest. Start the engine and listen to each injector individually. Maybe you can pinpoint it by finding the one that sounds different from the rest. A short length of rubber hose is good for this, or a mechanic's stethoscope. Some people put the tip of a screwdriver on the injector and then listen closely to the handle end for the noise transmitted through the screwdriver.florida33779 said:
A few ideas anyway. Maybe someone else will chime in with better ideas or the resistance values you need. Let us know what you do and how it turns out.
