      "Generally, this type of problem is either a loose or corroded electrical connector on the injector, a fouled injector (dirty or plugged) or a bad injector needing replacement.

      In over 45 years I have found that loose or corroded connectors were the cause of the electrical fault the majority of the time. I have found but a few cases where low voltage wiring became shorted or open (when left undisturbed).

      The majority of electrical problems were alternator related, starter solenoid wiring, oxygen sensor wiring due to the close proximity to the exhaust and battery related. The majority of electrical work was correcting customer-installed items such as high-power stereos and other parts or equipment installed incorrectly.

      The fuel injectors get their power from the fuel pump relay. The PCM actuates the relay as the key is turned on. This means, as long as the key is on, the injectors have power. The PCM activates the injector by supplying the ground at the necessary time and for the proper duration.

      Check the connector on the fuel injector. It is a plastic connector secured to the injector with a wire clip around the connector. Pull on the connector to see if it comes off easily. Remove the wire clip and pull the connector off the injector. Inspect the harness connector for corrosion or pushed out pins. Make sure the two blades are not bent in the injector itself. Correct any defect and apply dielectric grease and install the electrical connector. Start the engine and listen to the injector to ensure it is working. Use a long screwdriver to the injector and the handle to your ear and you can hear it clearly. If it isn't making a highly audible 'clicking' noise, it either has no electrical power to it or it has failed. If it was not clicking, pull the connector off the injector and check for power with a voltmeter.

      No power means the wiring to the fuel pump relay is at fault or has a loose connection. If it has power, probe both terminals on the harness connector and if the PCM injector driver is operating, the voltmeter will indicate rapid pulses. If pulses are seen, replace the injector. If the injector was operating, then it is either plugged or dirty. Attempt to clean it first. The kit to flush the injectors is inexpensive and will benefit the remaining injectors, possibly preventing a recurrence. If the flushing fails to solve the problem, the injector needs to be replaced."

      Not sure of the warranty status of your engine or your location to your dealer. Might be something you want to investigate or something you want to hand off. In either case I would not run or try to run the boat until the problem is resolved. They do make cheap injector flush kits if you decide to go that route.

      Keep us posted.

          Hi J2nh, I am having the same issue as per above. I feel silly asking this but where is the plastic connector for the injector? I don't really know my way around an engine too well so any help or pictures would be much appreciated! Thanks in advance.
