Fuel Injectors May Fail and Cause Drivability Concerns on Nissan 300ZX

The fuel injectors can fail and cause drivability problems. Often there is no Check Engine light and the failures can be caused by corrosion of the connector, clogging beyond the point of cleaning, and/or internal failures.

Engine was missing. Installed new fuel injector plugs and cleaned contacts of fuel injectors and now running on all cylinders again.

injector #2 failed, replaced fuel rail and injectors with new style. then injector #3 failed right away.
actually just bought my first 300zx. It's a bit of a mess and is running very rough. Just went through the plugs, found one coil pack was not plugged in and hoped that was the problem, but it's still running rough. No check engine light or any indicators. I assume a fuel injector problem but which one? need to buy a OBD1 scanner I think?
