When I started the boat on mufflers this morning it started rough. With any advance of the throttle it would act like it was starved for fuel and would shut down. I checked the injectors and noticed that the starboard side injector was not spraying at times and eratically at other times. Later in the day I purchased an injector tester and went back to start it again using the tester light.

What I found was on the port injector the light would blink with a strong light. The starboard side had no light at all.

Does anyone know what may cause this or where I should start looking for a fix?

It is obvious that there is no voltage to the starboard injector harness.

Thank you to anyone who may help !!!!
