I have a 1999 pc27r-8 it turns on and runs fine as well as idling. If I shut it off it won't turn back on. I have tried a new battery, fuel pump, and thermostat. What else would this be? Is there other things I should be looking at?
This makes no sense. Define "won't come back on" with more detail.
Engine won't crank after running? Engine cranks but won't start after it's heated up?
Komatsu PC25R-8 and PC27R-8 mount the 3D82AE engine. Hope to be helpful.
