Yes, the light should flash when the injector gets power. As far as the injector, make sure it is clean. When you connect it, you should hear it clicking. Also, (carefully) remove the injector and connect it to see if it only sprays gas when it should and not all the time. It should spray a fan like mist. Make sure to catch the fuel in a container and not let it to leak onto the engine. Protect your eyes and body from the fuel. Also, make sure it sprays at all.

Let me know what you find.

Can you take a picture of it and send it to me? It doesn't sound like an O2 sensor.
