PowerStroke Pressure washer won't start
When your PowerStroke gas pressure washer won't start, the spark plug is the most likely cause. Inspect it for a cracked porcelain insulator, burned electrode, or heavy carbon buildup, then test for a strong spark while the engine cranks. If there is no spark, replace the spark plug. A clogged carburetor is another common reason for a pressure washer not starting or a pressure washer that won't turn on. Stale or ethanol-blended fuel left in the carburetor during seasonal storage can evaporate and leave sticky residue that blocks fuel flow. Clean the carburetor with carburetor cleaner, or rebuild or replace it if cleaning does not restore starting. If the spark plug works, test the ignition coil and replace it if it cannot send voltage to the plug. A sheared flywheel key is less common, but it can prevent ignition timing if the engine stopped suddenly after striking an obstruction. These checks can help identify why your pressure washer will not start. Enter your model number to find the exact replacement spark plug, carburetor, ignition coil, or flywheel key for your PowerStroke pressure washer.
01 - PowerStroke Pressure Washer Spark Plug
Inspect the spark plug for signs of wear or damage. If the porcelain insulator is cracked, an electrode is burned away or damaged, or there is heavy carbon buildup at the electrode, replace the spark plug. To determine if the spark plug is defective, use a spark plug tester. You should see a strong spark between the tester’s terminals when the engine is cranking. If there is no spark, this indicates that the spark plug is defective and should be replaced.

02 - PowerStroke Pressure Washer Carburetor
The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the pressure washer for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and prevent the engine from starting. If the carburetor is clogged, try cleaning it with carburetor cleaner. If cleaning the carburetor isn’t effective, rebuild or replace the entire carburetor.

03 - PowerStroke Pressure Washer Ignition Coil
The ignition coil sends voltage to the spark plug while the engine is running. If the ignition coil is defective, the engine may not start. Before replacing the ignition coil, ensure that the spark plug is working properly. If you have confirmed that the spark plug is working properly, test the ignition coil with an ignition coil tester. If the ignition coil is defective, replace it.
Common
04 - PowerStroke Pressure Washer Flywheel Key
the flywheel key might have sheared in half. The flywheel key is a small metal piece which fits into the crankshaft and engages with the flywheel. If the engine stops suddenly due to the pressure washer hitting a hard object, the flywheel key breaks in half to prevent damage to the engine. To determine if the flywheel key is broken, remove the flywheel from the engine and inspect the flywheel key. If the flywheel key is broken, replace it.
