Optimax out of fuel

My 250 opti died yesterday just before we got back to harbour. Felt like we ran out of fuel even though gauge said otherwise. Have refuelled her but it won't start. Are there any tricks that I need to do I primed the water seperator. Or it could be another problem any ideas.

Don't forget there's a low pressure and a high pressure (and a lift) and the differece between pressures need to be within tolernce or the motor won't start.

Low fuel pressure side should 10psi and air side on the fuel rail should be 80 to 90 psi . As said before check fuses for low pressure side an report back

Kernow Buoy will have the answer - he's been studying a mid-life apprenticeship in Optimax at Black Dog Marine.

It must have been fuel. Even though we had 40 litres left the engine must have sucked some air when gong through a big sea. It has a 310 litre tank so that's all. Can think. Roaring again ow thanks for the ideas.
