You can check if there is no pulse on injector or spark using oscilloscope.

there is a pulse on the injector plug, not sure if its the correct voltage to open it up and the spark plug has a great spark. Ill go ahead and order a used 39790-S10-A020-M1 unit along with a used 37820- P3F-A54 unit. Ill let you know if that cleared up the problem.

tomoto123, Did you compare injector pulse waveform on working and faulty cylinders? Also you can use multichannel (four-channel is ideal) oscilloscope to check if pulses go at apropriate time periods.
