That's a confusing set of tests. Throw that in the trash.
Disconnect the #1 fuel injector pigtail/plug. Measure the two pins on the fuel injector with a multimeter, it should have 10 to 15 ohms of resistance.
If the injector is good, test the harness:
Driven side:
Test between pin 2, Brown/yellow wire, on the injector plug and pin 3 on connector C102. Expect around 1 ohm or less.
Test between pin 3 on connector C102 and pin 13 on connector C1 on the PCM. This is also a brown/yellow wire. Expect roughly 1 ohm or less.
Plug C102 back together. Check between C1(pin 13) and injector #1 connector (pin 2). There should be 1 ohm or less.
Power Ground Side:
Test between pin 1, brown/white wire, on the injector plug and pin 1 on connector C102. 1 ohm or less expected.
Test between pin 1 on C102 and pin 3 on Connector C4, there should be 1 ohm or less. This one is probably useless to test, a break here would cause all of the injectors to fail.
Reconnect C102. Test between pin 1 on the Injector #1 plug and pin 1 on C102.
Injector plug/harness test:
Reconnect the injector plug onto the #1 injector. Now test between pin 1 (brown/white) and pin 3 (brown/yellow) on C102. There should be 10 to 15 ohms of resistance. If not, you probably have a bad pin connection in the injector plug.
Here's how to read the Schematic.
