    Mercruiser 4.3L won't start

    Tried starter fluid already too. I am not sure when the boat ran last (before I bought it). Will get a new ignition sensor and change the plugs. Might take a few days though... will update once I swap those parts

    Mercruiser 4.3L won't start

    Yes got spark, at the bottom is the plug from cyl 1 but it's 3 sec between sparks, instead of 4 per second with around 500rpm starting

    Mercruiser 4.3L won't start

    Pored fuel into the carb, but she won't start. I do have some spark, but not very strong (see video). I will put new spark plugs in (came with the boat). Then the new sensor if needed.

    Mercruiser 4.3L won't start

    I sucked out all the old gas and put brand new gas in there. I put the old rotor and cap back on and it still wouldn't fire up. When I tapped the white green wire to mass I got sparks (bottom troubleshooting check).

    Mercruiser 4.3L won't start

    I went through the troubleshooting and I do have spark, so I think it's my ignition sensor or my timing is way off...

    Yes I did check for spark, but didn't see with my tool. I will do a wire check today and see what is hooked up wrong.

    Mercruiser 4.3L won't start

    Def a TB distributor... Op, I assume you verified no spark? I didn't see it mentioned. Also would check all of your connections, that engine looks even rustier than mine.

    It is 1990 boat, if that helps. The tach spins 360 degrees when I am trying to start it.

    Mercruiser 4.3L won't start

    Took the distributor off. The finger does turn. I can't attach any wires at the distributor, since it's direct wired. I can't measure any voltage at the coil with ignition on. Is that normal?

    Mercruiser 4.3L won't start

    Yes, those numbers are wrong, but the order is correct, just checked again. Got the purple and gray to the coil and the 3 cables to the distributor.
