Totally STUMPED!!!!. 2005 Volvo Penta 4.3 GXI issue

[erniegator1]

I was out on the lake last weekend when, while on plane, my boat stalled out. It would start for a second then die again. Finally had to be towed in (I love boating). My tech and I just spent an hour outside going through some things. Specifically, we put a fuel pressure guage at the rail and it reads normal when we turned it over but it would not start. We pulled the boat fuel line next and hooked it to an external tank to bypass the fuel tank. It would turn over but not start. We hit it with some spray. It would fire up for a second then stop. We pulled the Fuel/water seperator and checked it for anything. It looked ok. He is thinking it could be something with the computer. He does not think it is the injectors as it is unlikely that they would all go bad at the same time. Any thoughts on what could be causing this?

I appreciate any help.

Have you got a spark?

They will diesel on the start spray (ether) and it sounds like they're running. If your tech hasn't checked spark yet you need a different tech.
