  If your D-MOTOR Engine doesn't fire, several issues could be the cause. First, ensure the ignition is switched ON. Check that the fuel shutoff valve is also ON and that the fuel filter isn't blocked; clean or replace it if necessary. Confirm there is enough fuel in the tank. Inspect the ignition cable for loose connections or damage, and replace the cable if needed. Finally, check the spark plugs; if the gap is too big, change or re-gap the plugs.

  There are several reasons why your D-MOTOR Engine might not fire up. It could be due to the ignition being OFF, so ensure it's switched ON. Another cause might be a blocked fuel filter or the fuel shutoff valve being OFF; in this case, clean or replace the fuel filter and ensure the valve is ON. Insufficient fuel can also prevent the engine from starting, so fill the fuel tank. Check the ignition cable for any damage or loose connections, replacing it if necessary. Finally, the spark plug gap might be too large, requiring you to change or re-gap the plugs.

  If your D-MOTOR Engine does not fire, it might be due to several reasons. First, ensure that the ignitions are ON. A spark plug gap that is too big can also prevent firing, so change or re-gap the plugs. Check if the fuel shutoff valve is ON and the fuel filter isn't blocked. Lack of fuel or a defective/discharged battery could also be the cause. Inspect the ignition line for any damage and replace if needed. If the starting speed is too low, check the battery. Lastly, dry any spark plugs wet from condensation or fuel. In case of an inner mechanical defect, contact the engine manufacturer or an approved service center.

  To address a D-MOTOR Engine that won't fire, start by ensuring the ignitions are ON. Check the spark plugs and either replace them or adjust the gap if it's too large. Make sure the fuel shutoff valve is ON and the fuel filter is clean; replace the filter if blocked. Confirm that there is enough fuel in the tank and that the battery is properly charged. Inspect the ignition line for any damage and replace it if necessary. Also, verify the battery if the starting speed is too low. Finally, dry the spark plugs if they are wet. If none of these steps work, there may be an internal mechanical issue, and you should contact the engine manufacturer or an approved service center.
