That indicates the 2 wires you are testing are shorted together.
Inspect the harness carefully for any damage.

I suggested doing the test with the key on engine off.
With it running, you will not and cannot see the ECM grounding the return wire.

Also did that. I'm getting 0.00 on #2, #4, and #6 injector connectors with key to on (not running). Any ideas? #2 and #4 are working, #6 is not?

Put the black lead on a good machine ground and make sure you have 12 volts to the injector.

Okay, I would get a noid light and put it on the connector and crank the engine and see if it flashes while cranking.
You can rent one at a parts store.

Did you replace the injector? If the compression is good then it could be a bad injector.
