Answer
each injector has 2 wires, One wire is battery voltage to the injector and the other is the ground wire which the computer GROUNDS in side the computer to make the injectors fire.

check for battery voltage on one of the wires that goes to each injector with the ignition key ON.

If you have battery voltage on one of the wires going to each injector, Remove the 2 wire electrical connectors from the injectors and attach a test light in place of the injector and crank the car and the test light should flash. Move the test light to the wires that go to the other injector and you should get the same results.
