My engine has just 270 hours. Salt water boat & installed in 2016.
I was going about 6 mph for 30 minutes and one engine just died. It would crank but not start.
After I got into the slip I tried again and it did start for 30 seconds or so and then died. The longer I let it sit, it seemed like it would run longer.
I hooked up a gauge to the fuel rail and turned key on, got around 40psi (normal)
started it and this video is what happened
To me it looks like it runs out of fuel. I tested the fuel pumps in the module and both ran at 12v.
Filter was fine. Plenty of gas in tank, lines are all only 6 months old.
But maybe its just losing power so the fuel pressure drops??
at one point i ran the engine at 2000 rpm in the slip for a minute and it died. Then I start again and it idles for 20 seconds and dies.
So again, the longer it sits the longer it will run it seems.
I have spare fuel pumps, regulator and filter so I am swapping them out in the fuel cooler (gen 3 no paint flake issues).
My mechanic said it seems electrical. Try TPS or the main cord going to engine. Wiggle stuff and see.
He said gas tank vent could be clogged too.
I guess I had it in my head it was fuel related because it just makes the most sense watching it drop and no errors.
Edit: I hooked up a rinda scanner and it showed no error codes. After starting it and trying for hours it did finally show 2 codes. Crank position and cam fault. But I think its just because it was stalling out or not starting sometimes.
