What to do if Lombardini 9 LD 626-2 Engine does not start?
If your Lombardini Engine doesn't start, the issue might be in the fuel circuit. Possible causes include an obstructed fuel line, a clogged fuel filter, air or water leaks in the fuel system, a clogged tank cap vent hole, no fuel in the tank, a faulty fuel feeding pump, or a sticking extra fuel control level. Check these components to identify and resolve the starting problem.
