    2004 Mercruiser 3.0 Aplha One won’t start

    Yes, I have tried it all. There is no spark coming from the spark plugs. Which is odd because if fired up fine prior to the fuel filter change.

    There is fuel coming through the lines so I know the pump was installed correctly.

    I double checked everything and made sure it’s all back where it needs to be. I just installed new OEM ignition wires today and it still wont start. No physical damage to any wires neither.

    2004 Mercruiser 3.0 Aplha One won’t start

    Sorry, serial number 0M381522 I did check the rotor and it started fine until I changed the fuel filter. I had to remove the fuel pump to access the filter. Could it be bad spark plug wires?

    2004 Mercruiser 3.0 Aplha One won’t start

    I changed distributor cap, spark plugs, fuel filter & now it won’t start. Confirmed gas is running to the carb. Firing order is 1342, tested spark plug 1 and no spark. It started fine before removing the fuel pump to change the filter. Can anyone please help?

    2004 Mercruiser 3.0 Won’t start, misfires & runs rough when starts.

    I just did exactly that and it started like a champ! Thank you! I let it run and adjusted the idle screw and “air mixture?” screw. Is there a specific I should be tightening the screws and what is the ideal idling RPM? 🙏🏼 The same thing happened last time then I got in the water and it ran...

    2004 Mercruiser 3.0 Won’t start, misfires & runs rough when starts.

    Before pulling the plugs I labeled each plug to make sure they were put back in the correct firing order. 1342. It started and ran for a bit after then died and now it won’t start at all. The boat repair shop told me it might be the distributor cap so I replaced that and still same problem.

    Hello! Thank you for the quick reply! Engine serial number 0M381522 I used the ACDelco plugs, same part number for the original plugs I pulled. I replaced the distributor cap. I see no fuel or smell in the exhaust water. Seems like I’m not getting fuel to the carb because it’s not starting...

    2004 Mercruiser 3.0 Alpha One I changed my spark plugs, distributor cap, changed oil, changed lower unit gear oil & replaced the alternator & power steering belts. It started but ran rough at around 3000-4500 rpm, now it won’t start and blows black smoke out of the carb when trying to start. I...
