Well, it’s been a challenging summer!!!

Getting my Maxum (with a 2000 4.3L Mercuiser with Thunderbolt V Ignition) ready to sell while I wait for parts for my pontoon....now it won’t start.

Turns over ok but no start. Put a bit of gas in the carb and fires right up (but doesn’t continue to run).

After attempting to start, the fuel pump continues to run (maybe louder than I remember?) for about 5 to 10 seconds. When I first turn the key on I don’t hear the pump.

At the end of last season I did the winterization including adding fuel stabilizer.

Any suggestions on diagnostic steps would be very much appreciate.
The service manual doesn’t appear to have test procedures.

Hmmm. I posted in the wrong forum section. How do I move it to mercuiser section?
