    Mercruiser 5.0 no power to fuel pump when ignition ON

    But on the other hand if it’s 9V at the coil the ignition should work…. I think of putting 12V from batt to + on the coil

    Mercruiser 5.0 no power to fuel pump when ignition ON

    Can shift interrupt switch block the ignition maybe? I don’t have any tools to check if the coil is making spark to the distributor… Can disconnect gray (-) wire from coil help isolate the failed tacho?

    Engine cranks but without starting, even when spraying start fluid doesn’t work… I’ve got 9V at the coil +, 12v at the orange at alternator. Kill switch is in RUN, I don’t have red circle CB at the top of the engine. Maybe fuse at the starter how to check it? All instruments works at the dash...

    Mercruiser 5.0 no power to fuel pump when ignition ON

    Yes it’s carb, ok I’ll get back when we will be at the boat. I don’t remember if the gauges were alive when keyed on. I’ll check that. For sure the engine was cranking a little until batteries die, and also there was continuous beep ( I assume because of no oil pressure )
