What to do if my LONCIN Engine does not start?
- B
  Barbara ButlerAug 7, 2025
  If the LONCIN Engine does not start, several factors could be at play. First, ensure that the fuel system is adequately supplied with diesel fuel by refueling it. If the diesel fuel is not the recommended type, refuel with the correct one. A clogged fuel filter could also be the issue, so replace it. Furthermore, faulty spraying of the fuel injection could be preventing the engine from starting; in that case, purge or replace the fuel injection. Finally, check the electrolyte, recharge it, clean the terminals, and retighten them.

  If your LONCIN Engine lacks power, it might be due to a clogged fuel system. Try purging or replacing the fuel valve, filter, or cock. Another potential cause is faulty spraying of the fuel injection, in which case you should purge or replace it. Also, check the fuel injection pump for faults and purge or replace it if necessary. Finally, a clogged air cleaner element could be the culprit, so clean or replace the filter element.
