    HELP 2005 5.0 MPI OVER REV

    Yesterday I started tearing tape away from the relays back into the harness and checking wires after successfully bench testing the relays and determined they were good. Today I put all the relays out of the way and made them static so I could move things around without moving the harness. When...

    Oh, the one on the back left of the motor round pin, I assume provides power to the harness?

    HELP 2005 5.0 MPI OVER REV

    So today I went our to the boat, turned the key and age started up fine. Cycle the key and fuel pump coming on and off no problem. I decided to bench test the fuel pump relay and it's opening and closing no problem, showing 77OHm resistance and has continuity. I reinstalled the relay and then...

    Relay and plug seem clean. I'll definitely put in water for another go, and yes she's made me super nervous. 28K and I got 1 ride in it. Near another 5 K and still not quite clear lol.

    HELP 2005 5.0 MPI OVER REV

    So I shouldn't bother paying to see if the calibration is correct ? If she's running ok then don't worry about it ?

    HELP 2005 5.0 MPI OVER REV

    How do I determine the ratio, I guessed it's the 1.62 or whatever but I'm uncertain. I checked today and cycle the rpm setting on the back of the Guage and rpm seems to have normalized at 600rpm idle. I guess next step is again put in water. The ECM is new to me I bought online, when I got it my...

    HELP 2005 5.0 MPI OVER REV

    I just removed the tack and cycled the position switch, I was getting an erratic reading at idle about 1100, now she is idle at 6 even so that's a start. Maybe onto something. Sea trial again. Hopefully headed in the right direction

    Just checked with him and he said it does tell you RPM, he should be fairly well versed lol my "friend" is a great guy I met at work who specializes in repair of the German Harbour crane that I operate. He's been helping me through the ECM failure diagnosis as well so he's up on what's been...

    Gosh I hope not lol. Never know I suppose. I will try the cycling the switch tomorrow. Don't have a shop tach, how does that work to verify?

    I am going to check this asap. Thanks everyone. I'll be back with an update. Maybe the engine is not over revving at all and I don't need a prop change

    HELP 2005 5.0 MPI OVER REV

    Is there a chance that the new ECM I have installed is not the right calibration that's throwing off the Guage? I have a read out of the old faulty ecm before it failed and no indication that there was a tach issue. Hiw do I verify the tach setting

    HELP 2005 5.0 MPI OVER REV

    I am now suspect. To be honest it was showing closer to 6000. Would the engine be bouncing off rev limiter? She sounded relatively smooth but I was concerned with the Guage so I slacked off. See photos.

    HELP 2005 5.0 MPI OVER REV

    I am absolutely still figuring out all the bugs as stated prior to ECM failure I couldn't get the acceleration or top speed to reach as the MAP was faulty. Now thay I replaced that and put in the new ECM she's got the power. She's idle at around 1000 and sounds fine, she did not seem to be...
