Please help I'm at a loss here!!!!
Boat&motor- 1986 21' bayliner capri-aq225e #cu56837.....
ok the boat ran 2 months ago. i decided i was gonna pull out all the carpet and refinish the inside with no carpet, like i said boat ran the week before i started this project...i completed the project boat would not start.... i read a lot of the threads and started with ignition system....no spark...i replaced the plugs and wires about 3 months ago so i started with the points they were bad so i changed the points and condenser and the coil just to be sure....i set the points with a dwell meter as everyone here said..... 30deg while cranking i read that here somewhere.... i now have spark from the coil wire and from the 2 plug wires i checked.... now the engine turns over trys to start for about 1 to 3 seconds and stops..... it seems like when i turn the key back to the run position it stops...i dont have a kill switch.... so i thought it might be a fuel issue so i changed the filters and have plenty of gas from the line in front of the carb.....so i rebulit the carb in accorance with one of the videos i found hear.....motor still does the same thing.......please help i'll try anything to get thing fixed since the Navy dont pay me enough to have someone else do it.....thanks in advance.....

Re: volvo penta starting issue

you have a purple wire not connected somewhere

check the purple wire circuit, you will find it broken/unattached somewhere
