    Mercruiser 3.0 No Spark issues

    This is what I was concerned about. Don't want to go jamming the probes in, but can't tell if I am getting a good connection or not

    Mercruiser 3.0 No Spark issues

    I just tested my ignition coil and did not get any resistance readings at all on steps 3, 4, 5. Does this sound likely? I am almost positive my meter is fine, as I was getting readings when testing the pickup coil. If so, I will order a new ignition coil

    Mercruiser 3.0 No Spark issues

    Thank you, on my coil there is a plug with the purple power wire and the grey which I understand to be the tach/shift interrupt wire. I am not sure how I would disconnect the tach at the coil without also disconnecting the purple power wire

    Mercruiser 3.0 No Spark issues

    Thanks guys. I will test the coil today with my meter. I have reconnected the shift interrupt switch asI could not find out how to properly disconnect it. My tach is also entirely disconnected at the dash. Here is a pic of my shift switch. The right side wire goes to the terminal post that has...

    Mercruiser 3.0 No Spark issues

    Yes, I have 12V at the coil. Also my tach is disconnected at the dash to rule that out.

    Mercruiser 3.0 No Spark issues

    Thanks for the insight, you are speaking of the 15-20AMP fuse? Mine has the fuses on the dash if that is what you mean. I will check that as well

    Mercruiser 3.0 No Spark issues

    Just did this test. I am getting no reading / infinite when testing either green or white lead to the dist housing. I don't have a X100 on my multimeter, but I set to x10 and receive a steady 200ohm between white and green.

    Mercruiser 3.0 No Spark issues

    Boat turns over but just won't start, this is why I don't think killswitch / safety lanyard or gear is the issue

    Mercruiser 3.0 No Spark issues

    I am not exactly sure but I do not think it is points. From what I can tell there is not a +/- terminal on my coil to test. Just two sets of wires coming out of the plugs. I will attach some photos of coil and dist

    Mercruiser 3.0 No Spark issues

    Just picked up a new to me 1991 Stingray with a Mercruiser 3.0. Boat ran great the first 5 times I took it out. Last time I was out boat was hard to start, then after I had stopped for a bit would not start back up. I went through the fuel system and it is all good. I hooked up inline spark...
