white smoke and fuel in exhaust

[Peter]

While motoring at about 2800 rpm on a 2GM20F, I suddenly lost power and eventually slowed to about 1000 rpm at which point we shut down. I found the screen in the fuel pickup tube to be blocked solid, so I disassembled, cleaned and took the opportunity to replace the fuel line and install fresh filters and bleed the system. Now the problem I'm seeing is lack of responsiveness on the throttle, a lot of white smoke in the exhaust and a sheen of what looks like unburned fuel in the water from the exhaust. (the engine is sluggish and doesn't feel right) This engine burns no oil and I've never really had a problem with it. I'm starting to think this may be several things manifesting at the same time and not entirely related to the clean/filter change?Help!

Still air there

Peter, It sounds like there is still air in the fuel system. Try to bleed it again while it's running. Do it at the secondary filter, fuel compression block and at both injectors (in that order). It worked for me. Good Luck.

Check water flow.

White smoke may be steam caused by overheating from lack of waterflow thru the system. I see white smoke first when my sea strainer or hose gets clogged, followed by the overheating buzzer if I don't recify the problem

Embarrassing resolution!

Turns out the problem was due to the decompression lever not being in the fully closed position - closed the lever and hey presto everything was running just great! Peter
