Hey all,
looking for assistance. This thing is kicking my butt.

2001 Optimax that stalls out after warming up when trying to put load on it. Checked VST and it was clean. Replaced both water separators and it was fine. Starboard motor running off same fuel tank ok.
checked compression - 105 every cylinder.
checked temp sensors, within spec.
checked wiring to ECU and pinned out harness, confirmed sensor grounds ok.
Replaced spark plugs
replaced one coil with broken connector body
had leaky thermostat gasket - replaced gasket.
warning sensor works upon key up, does not indicate a fault when shut down
fuel pressure appears ok
pumped bulb during acceleration to try and bypass lift pump/siphon valve and got no change
everything appears clean.
any ideas? This thing has got me feeling pretty down. I caved and ordered diacom to try and get more info, which will be here Friday.
thanks
dan
Smartcraft does indicates a fault of low oil and also no temperature input. I don’t know if this means anything.
