By Peter Meier. Fuel flow and injector faults can result in drivability problems. Some OEM scan tools, as well as some high end aftermarket tools, allow you to perform power balance and/or injector balance tests on those OEs that support such a test. Injector balance can also be done using a tool that fires the injectors individually while you measure the drop with your fuel pressure tester, but this can be a time consuming task. There is another way to check this flow, and it uses a DSO and a special pressure transducer.
