I need to check one of my injector's on my 1995 502 MPI. Do I need to de-pressurize the fuel system before I check it. I have not turned the motor over for two days?

I have borrowed a friend's noid lite to check one of my injector's electrical current. I can't get in touch with him, therefore I'm asking you all. Is it as simple unplugging the harness from the injector and plugging the harness into the noid?

Thanks,
Mike

Yea, that is all you have to do. Also note, that the hot wire will always be hot, when the switch is on. and the injector is pulsed with the ground wire.
Hope this helps.

P29 SCARAB is right on. The fuel pressure makes no difference for this test.

Thanks guys for you help. I appreciate it. Going out to test and start up hopefully.
