More engine stalling problems

[runner911]

Well the Volvo Penta D3 110 fitted in my Merry Fisher 655 has done it again and stalled when 20 odd miles out to sea !

In a previous thread a couple of weeks back I described how the " Water in Fuel " alarm had been activated when returning from a fishing trip. As a result I drained the pre fuel filter bowl and fitted a new pre filter. I then unlocked the bleed bolt on top of the fuel filter proper on the side of the engine and pumped the primer button a few times. However only neat fuel appeared and I thus assumed therefore that there was no air in the fuel line between the pre-fuel filter and the fuel filter.

On my first trip after that , I had switched off the engine whilst drifting over a wreck. Approx. 30 minutes later , I re-started the engine. After 10 seconds the engine stalled. My immediate reaction was " Oh s**t. " However the engine immediately fired when I turned it over on the starter and did not give any furthur problem .

Then yesterday p.m. on another fishing trip , it did it again.

The engine runs fine, although staring from cold seems to be a little more difficult of late. The problem has only manifested itself since I replaced the pre fuel filter.

Is it possible that there is air somewhere in the fuel system ? If so how do I remove it ?

Volvo Paul ?

I am sure that Paul will give you a more comprehensive repy, but it does sound to me, very much like air getting in and the fuel draining back whilst standing.

A few simple checks, did you replace the gasket rings at the top and blottom of the filter? Could you have got them twisted?Did you replace the crushable seal washer on the bolt that goes through the middle of the filter and holds the whole assembly together?

All three problems that I have had at different times in the past, I have at last found a reliable mechanic.

Filter

We found that although the fuel filter was done up we were getting common rail pressure fault codes. Get a boa constrictor the multi use tool and you will find you can get another turn on the filter.

We had same issue filter change and out for a run then a complete shut down. Would restart and go for a mile or so at low revs fine as soon as high speed shut down.

After loads of switch and sender changing, cleaning electric connections we did that to the filter and cured it.

Had the samething with our 655 with the D3 before we rejected the boat , it was hard to start ,then it would stall, it turned out to be air getting into the pre filter (Volvo part)on the inlet side nipple, it had been knock when they replaced the gearbox it looked fine but it had move and was lose.
