Engine ser# OW003759. Starts for 20 seconds, then dies. Will not re-start. I have pulled codes (below) and am concerned about the fuel pump. Here is what I know:

First - in the manual that I have it only has codes that go up to about 50; several of the codes that it is reading are above that. I cannot find the complete list anywhere? These codes I believe are 'normal:12, 75,94, 130. The other codes that I read, that I cannot find anywhere, are : 9, 43, 104, 110, 119, 151.

Second - this engine was just pulled to fix an oil leak. I hired a guy who was supposedly a Mercruiser mechaninc, that ended badly with him quitting with no notice and I have multiple issues on my hands from his "fixes". So what exactly he did is a mystery. The engine will start, run for about 20 seconds, then die and will not start until the next day. Done that twice so far. When it is running it is smooth and sounds good. I can hear the fuel pump cycling, and have verified that it is getting fuel past the fuel/water separator. When it dies, it seems like a fuel starvation issue as it starts to run a bit rough and then fades away- different than if the ignition was turned off. I replace all filters, the tank is full.

Third - the fuel pump intake looks a bit askew- as if it was impacted. I was going to just replace it for good measure until I got the price ($435) from the dealer. Then I decided to not just throw money at it until I have diagnosed correctly. It sure would help if I knew what these codes mean.

Any help / advice is appreciated.

Bravo 3. Is that the same pump then?

Have not tried a remote tank; I did verify that the vent was not clogged, even tried with the gas cap off.
