When the fuel filter gets dirty, it clogs up and prevents the engine from receiving the required fuel. This results in the tractor jamming and being unable to start. 

Always ensure that the fuel filter is clean. 

  1. The first thing to do is to remove the cap from the filter. 
  2. Now disconnect the terminals. Start with the negative first and then do the positive next. 
  3. Locate the fuel filter according to the manual. Put a bucket under the filter to catch any escaping gas or fuel once you detach the fuel lines. 
  4. Next, detach the clips fastening the fuel line before removing the fuel lines altogether. 
  5. Use a pressurized carburettor cleaner then to clean the inside of the fuel filter.
  6.  Make sure to tap out any piece of loosened debris. Reatttach the filter once again. 

The only cost is with the carburettor cleaner. You can get that easily for $2-3.

Empty Fuel Tank: Fill Fuel Tank 

Fill Fuel Tank 

Another common cause for New Holland not starting is an empty fuel tank. If the engine is not starting, the first place to check is the fuel tank. Make sure there is enough fuel there to run your vehicle. 

  1. To fill the tank with fuel, you must make sure to prime and pressurize the tank first. Excess air stuck inside the fuel lines will need to be released. A fuel primer pump is needed for this. 
  2. You need to locate two things. The first is the fuel primer pump, and the second is the bleed screw. 
  3. Unlatch the bleed screw. This will help any air trapped inside the fuel lines to escape. 
  4. The fuel primer needs to have pump inhibitors for 5-12 minutes to ensure air from the tank escapes. 
  5. To proceed to the process of getting the fuel pump replaced, the bleed screw must be kept tight now. 
  6. Restart the engine. If it doesn’t work, start the whole process again from step 1. 

If the fuel pump is replaced, then it will cost between $200 to $1100.

  3. Make a solution of water and baking soda and use that to clean the posts. 
  4. Before reattaching the terminals, you must make sure to dry them off first. 
  5. If none of the steps works, then your battery is dead and you need to get a replacement. 

If the battery is completely dead, you need to get a replacement which will roughly cost between $140-$200.

It is also possible that a key for a different tractor is used, resulting in the situation. To get the ignition switch unstuck, you need to use lubricant inside the keyhole. 

Pour some lubricant inside the keyhole and see if there are any excessive sprays or leaks that are coming out. Remove them immediately Any dirt or dust clogging up the keyhole will also be flushed out.
