Yep, for your year, you should have +12v at one side of the injector at all times.

The other side is picked by the ECU which causes the injector to fire.

When you say "it isn't turning on", what do you mean exactly? Does it crank and not start? Do you have spark? Do you have good fuel pressure?

Pull your CAS and see if the injectors are clicking when you turn it by hand. Of course, you need to have the car turned to the "run" position. You don't have to crank it. Have you pulled codes?
