I have a boat with a Volvo engine,Gxi-f , 5.7 ltrs,V8,320 hp,the boat was running well and suddenly it lost a
lot of its power,checked so many things and finally figured out that 4 of the injections are not working well,no electricity in them,i was told that the module is broken and i have to change it then i was told that this is a safety system that protects the engine,runs with half its power,and this is due to some other problem in the engine,would you please advise me if this is true and what to do.
Many thanks and best regards
Omar
