Engine overheating	Damaged components in the coolant system	Replace the damaged component.
Rough running engine	Damaged ignition switch	Replace the ignition.

Problem 1: Engine Will Not Start

The engine not starting can be because of problems with the fuel filter.

Solution:

Replacing the fuel filter located inside the fuel pump will solve the issue. 

Tools Needed: 

• Pliers
• User’s Manual

Step 1: Disconnect the Battery

Place the lawnmower on a flat area and then switch off the engine. Then, disconnect the batteries. This is to protect yourself from an electrical shock and to maintain your safety.

Step 2: Locate the Fuel Pump

Inside the fuel tank is normally where one will find the fuel pump on a John Deere LX277. It will be necessary to remove the fuel tank from the mower. That is in order to have access to the fuel pump.

Mostly, removing the fuel tank only requires the removal of a few clamps that are holding it in place. Use the plier to loosen the clamps. And then remove it from the mower altogether.

After the tank has been taken out of the way, you will have access to the fuel pump. The fuel pump can either be found at the very bottom of the tank. Or anywhere within the tank itself. 

The precise location of the fuel pump in your John Deere LX277 might change depending on whatever model you have. 

So it is strongly suggested that you consult the john deere LX277 manual that comes with the model that you own. Because it will have comprehensive instructions on how to find the fuel pump and gain access to it.

Step 3: Remove the Fuel Filter 

Use the pliers once more. This time remove the clamps that are securing the fuel filter in place.

It is important to remove the fuel filter from the fuel line with extreme caution. Be very careful not to let any fuel leak out.

Step 4: Install the New Fuel Filter 

Simply replace the old fuel filter with the new fuel filter in the same location as the old fuel filter. Check that the arrow on the fuel filter is pointing in the direction that fuel is being pumped through the system.

Put the clamps back on the filter so that the filter can be held in place securely. After reattaching the battery and starting the engine, check for any leaks that may have developed.

You can go for a test drive in the mower if everything seems to be operating normally.
