Dornier 228 Go Crazy?
 

Is some one there know why a Do228-TPE33-5 engine would behave so crazy that 1st and 2nd start are fine,but always 3rd start the engine doesnt light up???!!! tried changing speed switch,fuel HP pump,cleaned HPrelief valve ,start pressure regulator,flow divider and nozzle manifolds still nothing!!! can i go ahead to change the remaining? ie the engine and keep the pump and the rest?
In anothe engine ,the oil tank vent is always breathing vapoured oil on shutdown.....have cleaned the vent screen..Pliz pump your ideas.can as well reach me quick on [email protected] :ugh::ugh: :confused::sad:

Steve sent you a note on the non starting engine, and sounds like you might have an issue with the the lube/scavenge pump on the other one.

Yes, just go ahead and change the engine, lol!
