    The ECM temp sensor could but the temp gauge wouldn't

    Detailed wiring schematic for 43GL-PEFS

    Search for 1 watt diode and that will be OEM size If you want get a 2 watt to handle more current Cost about a buck each or less

    Volvo Penta 5.0FIPNCSCE SLOW mode

    If the Tach is causing the motor to miss then the ECM might think something else is happening

    Volvo Penta 5.0FIPNCSCE SLOW mode

    It's very rare to have a coil go bad. Folks replace them all the time with no change With rpm's all over the place maybe the Tach is an issue. Disconnect the gray wire on back of Tach

    Detailed wiring schematic for 43GL-PEFS

    I don't have a pefs but this is for the GL fuel pump. In most cases the diodes are next to the relay

    Yes, you are correct

    New 5.7 runs and shuts off

    You can do that, but could be the Reg you have is not set at 30. Installing another Reg to control the first just means more issues, but it's your boat

    New 5.7 runs and shuts off

    The Reg screen, but you said it's new and came with new Reg Partial collapsed fuel return line There is a Reg in the TB but that should have no effect on pressure because if Reg releases any pressure it has no place to go. Most TB Reg's are just to dampen fuel pump pulses Only other thing is...

    Bravo 1 low water pressure

    I'm not seeing any issue with water flow. Hope someday someone will come up with a fix to fake the sensor to the ECM

    Volvo Penta 5.0FIPNCSCE SLOW mode

    Looks like Horigan was leading you in the right direction Without checking for codes we're guessing The oil and temp switches should be able to be un-plugged. If on of them is grounding out (telling ECM to SLOW) this will show all good to ECM

    With other running fine off same gas then look at the carb, probably clogged up a bit

    Volvo Penta 5.0FIPNCSCE SLOW mode

    Adding good gas to bad gas just makes more bad gas. If it is bad it needs to be drained and maybe used in a lawn more if it's not to terrible Take the filter off and pour contents into a clear container. The gas should be crystal clear and not smell like anything other then gas

    Volvo Penta 5.0FIPNCSCE SLOW mode

    Welcome Your motor has a ignition module but not a ECM, has carb. Don't see it going into any kind of safe mode, but may retired timing "if" it has a knock sensor. Don't see a knock sensor with the brief look over the parts My guess is you have a fuel issue, and once fuel goes bad it cannot...

    2010 350 Mag MPI bravo 3 gaurdian mode issue. 5% power

    Unsure about exhaust co but would lead me toward the exhaust O2 sensors. Being it happens at 3000 rpm try disconnecting the in-gear switch on the shift plate. Probably won't change anything but it also won't hurt anything.

    New 5.7 runs and shuts off

    Sorry didn't realize you posted requesting the part number. I merged the threads to keep them together Part number is 807952A1 That said I'm using 1999 to 2001 TBI because I don't have your serial number. Might have missed it

    Detailed wiring schematic for 43GL-PEFS

    There are 2 diodes going to the relay coil side, and if the one on the ALT side shorts it will keep the relay pulled in. Your pump is running without the relay installed so there is a short or PO rewired it direct because they may have had the diode open

    350 Mag Mpi hard to start when warm or hot

    Check resistance of ECT cold and hot Changing more parts can induce more issues As the throttle increases further does the voltage start to increase then, or still lower? Your sensor is a MAP and TMAP, so it measures pressure and Temp. As Temp rises ohms lower
