Checking Cold Start Valve

[chiefmd]

I'm in the process of replacing numerous parts to remedy "running rich" in a 78 280Z. The last item is the csv but I want to be certain that it is or is not functioning. Is there any way to bench check it off the car, similar to the 9 volt test for the injector. I know you can check it while its installed on the car but I'm working on the motor and don't want to put everything back just to check the csv. Thanks

You'll need fuel pressure along with current to test the csv. So you'll either need a pressurized fuel injection cleaning cannister or the car itself to properly test it.
