starting problem when hot volvo penta

[peter_mayers]

Hello;<br />I am new to boating. I bought a seaswirl 3 weeks ago, It has a 96 volvo penta 5.0 Fi in it. I have a hard time starting the motor when it is hot and sits for a couple of minutes. When it is cold, or if it was just shut-off it will fire right up. When it sits for few minutes or even an hour,I have to crank for 40- seconds before it fires, and I can smell gas. If I put full throtle on it fires quicker but still hesitates. The previous owner said he had that problem but just lived with it. I put 3/4 of the tank of fresh gas, but it behaves the same. Any ideas on what the problem might be? I am pizzled since it only happens when it sits for a while.<br /><br />Thanks in advance.

i hope you are not too "PIZZLED" pete,.<br />when you have shut it off warm, take off the flame arrester on the top of the motor, (air cleaner)<br />and look to see if the injectors are dripping.<br />they are supposed to hold fuel pressure in the system, if they drip a little, it will "flood" the motor slightly, that is why it starts better when you open the throttle, it gives it more air, <br />much like putting the accelerator to the floor to clear a flooded carb,. the injectors might need new gskets/o-rings,..

Thanks nick, you cleared up some of my pizzle. **** fat fingers. My spell checker is also broken, and is getting worse as I get old. Anyway, this sounds very probable and I will check the injectors this weekend.<br />Thanks.

I had some trouble finding flame arrester. I don't think it is a leaking injector since the engine has eight of them. Do you think it would be possible for most of them to leak? Any more ideas? I am starting to think it is somehow my fuel pump?

I have talked to a mechanics and they are backed up for at least 2 weeks. He is also saying that it is getting flooded. Anyone knows what the problem my be? Should I take all injectors out, and inspect them? How should they look like?<br /><br />Any help is greatly appreciated.
