I have looked thru lots of posts and I am probably missing the answer but I am hoping someone can help me here. I have a 2007 Sea Ray 260SD with a single 350MPI / Bravo III. Computer is a Mercruiser ECM 0501 The problem is that it will start but it will not stay running. I have Diacom computer software and do not have fault codes, no horn alarm sounding.
I have spark.
New wire harness on motor
I have fuel and fuel pressure at the rail 43PSI. Fuel is new, filter is new, injectors are flow matched Bosch and new.
Will run on starter fluid and can get to idle speed with the starter fluid(will die once the starter fluid is gone)
I have checked the injectors for signal with a noid light, all get signal
When I turn the key, I hear the fuel pump, turn key more the starter engages and spins motor, after a few rotations the motor will fire off, then die. Evertime same exact response. If I pump the throttle I can get it to spit sputter and stay running (if you want to call it that while I pump the throttle) Occasionaly I can get it to rev past the 1500 mark and it will rev up and down sounding normal while I move the throttle up and down.
My question here.. could this be a computer problem or is there a sensor that could be causing this? Any help is appreciated
