2005 Sea Ray 300DA with 5.7L Mercruiser 350 MAG MPI HORIZON BRAVO3 ENGINES
The boat is new to us. It had been running perfectly.
Suddenly the stb engine will crank but not start
Port engine runs fine. When I turn on the ignition I can hear a click of the fuel solenoid and whine of the fuel pump. Stb engine - no solenoid click and no fuel pump whine.
Batteries are fine the engine cranks well, just do not fire up
Thanks!

- Changed fuel filter
- Engine will start and run if fuel is dripped straight into the intake
- 20 amp mini fuses on engine (which I believe one of them is fuel pump) look ok
- I switched both relays from port engine to stbd engine. Still same condition port will run but stb still will not start. Therefore I believe the fuses and relays are ok. It appears to be something causing the fuel pump and fuel shut off solenoid not to get electrical power?
- Will changing the IAC make a difference? I could not start with increased idle either
Thanks!
