The chart for P0200 says to find which cylinder is misfiring first, then test the injector harness for that cylinder (short to ground/power or open) then with a noid lamp. If the noid lamp flashes while installed on the faulty injector circuit the chart moves towards injector replacement.
Also, There are 2 fuses. One for the odd bank and the other is for the even bank. They should be labeled Inj1 and Inj2. The injectors should have voltage when the key is on and then the PCM controls the ground circuit to pulse the injectors.
