A pressure washer is a useful tool for cleaning various surfaces, from sidewalks and driveways to decks and siding. However, if you’re experiencing difficulties with your pressure washer, such as it being hard to pull or not starting at all, it can be frustrating and hinder your cleaning tasks. Understanding the common issues that may cause these problems can help you troubleshoot and resolve them, getting your pressure washer back in working order.

One possible reason why your pressure washer is hard to pull or won’t start is a clogged or dirty fuel system. Over time, fuel can become stale or contaminated, and it can clog the carburetor or fuel lines. This can restrict the flow of fuel to the engine, preventing it from starting or making it harder to pull the starter cord. In such cases, it may be necessary to clean or replace the carburetor, drain and refill the fuel tank, and check for any blockages in the fuel lines.

Another common culprit behind a pressure washer that is hard to pull or won’t start is a faulty spark plug.
