Can a worn out spark plug cause an engine to stall?
Old, worn out spark plugs may fail to fire, causing a misfire or even making the engine stall. Disconnect the plug wires and use a spark plug socket to remove the plugs and replace them. You may also consider replacing the spark plug wires. Be sure to reconnect the same spark plug wires to the same cylinders when done.

What causes a pit bike engine to sputter?
The problem of having an engine “sputter” is typically caused by a fuel system issue.

Why is my fuel pump not working in my Volvo?
DO NOT hold the wire as it may shock you if the ignition system is working. If you do not see a spark or hear the plug wire snapping when the engine is cranking, the fault is in the ignition system. If the engine has spark, it may have died due to a loss of fuel pressure. When fuel pumps fail, they usually just quit with little or no warning.
What to do if your fuel pump is bad?
Should you encounter a bad main fuel pump on your car, always inspect and/or replace the in-tank fuel pump, so that you can verify the condition of the filter sock. A bad or deteriorated in-tank filter sock will lead to fouling both fuel pumps with dirt.
