On checking the fuel injector system.
Using a test light connected to ground at one end and the probe testing the connector terminals.
When I turn key to On and test either side of injector connector, both sides on all injectors are hot.
You say only one of the 2 pins should be hot.
You say nothing about what to do if both sides are hot.

Buy a noid light at most autoparts stores and check that injectors are pulsing. They are usually $20.

The reason they are both hot is because you are testing it while the injector is plugged in and the current is running through the injector but you do need to test this with a noid light as advised.
