89 8.0 onan diesel gen set, hard to start

[Gregory OConnor]

The steel lines after the high pressure injection pump should squirt
out with a pulse when the engine is turned over. I loosen one at a
time while cranking the engine. CurtS had issues with his Yanmar (
john Deere)and it would not start unless the return lines were let
open. it may be time for injector cleaning. If it was my genset, I
would pull off the injectors and have them bench tested and rebuilt.
You could also check if there is a good flow on the supply fitting to
the high press injector pump. Keep the batteries fully charged while
cranking the genset over because low battery turns is sure to eatup
the starter. If it was the injector spray, replace the engine oil
after you clean up the problem. The Kabotas wash out when they dont
start and I have seen as much as a quart of Dfuel make its way into
the lube oil.
