5.0 Volvo Penta Motor will crank and immediately shut off

2005 Chaparral SSi 236 with 5.0 Volvo Penta. I've had no issues with the boat cranking until last week. Crunk right up and went 3 minutes down the lake and turned it off for about 5 min. Tried to start it again and it turns over and cranks up for just a split second. Charged battery to make sure it's getting full power. Had someone check the fuel pump/filter and it all looked good. Any suggestions? I had heard inboards were nothing but trouble and I'm hoping this will be something simple.

5.0 not cranking
by: Freddie

If your high pressure pump isn’t pumping, this will happen. Check fuel pressure at the fuel rail with a fuel pressure gauge. If no pressure, unplug high pressure pump (on the right looking at your fuel pumps), jump it from the battery, if It builds pressure, check your fuse, relay, and plug connection. My plug connection just had to be cleaned to fix mine. These pumps are painted inside and they sometimes need to be cleaned out.
