Need Help! Problems with Engine

Hi

I have x30 2007 with 350 engine. When I try to start my boat it only runs 30 or something seconds proberly and then dies. It doesnt matter if the rpm are high or not. And if I try to start it straight a way it wount start or it is realy hard but if I try after 5 min it runs smoothly 30 and then dies.

I just changed our alternator and after that it run smoothly. We ha less than half tank fuel.

I was thinking that maybe the problem is in the fuel pump but I can hear some noise and shacking when I put the power on.

Any ideas guys any help would be much appreciated.

Jaakko

use search feature on top of page and you'll come up with the solutions...too many variables to answer...but Willy T is correct...you must check things out...check the furl pressure...search and you'll find out how to do that. good luck!

The relays and fuses should be at the rear of the engine, fairly close to the ECM (brain). Do you know what a Bosch relay looks like? That's what you need to look for.
