The John Deere 318D, like many compact skid steer loaders, is a vital piece of equipment for construction and landscaping professionals. Known for its versatility and reliability, it’s a go-to machine for both small and large-scale jobs. However, as with any piece of heavy equipment, users occasionally run into issues. One common problem owners face with the John Deere 318D is a hard starting issue.
This article explores potential causes and solutions for a hard-start problem in the John Deere 318D, providing insights and tips to keep this reliable machine running smoothly.
What is a Hard Start Problem?
A "hard start" issue occurs when the engine of the machine struggles to start or takes longer than usual to fire up. This issue can manifest as the engine cranking slowly, or it may crank normally but fail to start right away. Hard starts can be frustrating, especially when you need to get the machine up and running quickly.
In the case of the John Deere 318D, hard starting can stem from a number of potential issues related to the fuel system, battery, or electrical connections. Properly diagnosing and addressing the root cause can save time, money, and stress down the road.
Common Causes of Hard Start Issues
1. Battery and Electrical Issues
One of the most common culprits behind hard starts is an undercharged or faulty battery. The 318D requires a solid charge to properly turn the engine over. Over time, batteries can lose their charge or fail altogether, especially in colder months.
What to check:
Fuel delivery problems can also cause the John Deere 318D to have a hard start. Clogged fuel filters, air in the fuel lines, or a malfunctioning fuel pump can all disrupt the engine’s ability to get the fuel it needs to start.
What to check:
The John Deere 318D, like many diesel-powered machines, uses glow plugs to assist with starting in cold conditions. If the glow plugs are faulty or not functioning correctly, starting the engine in cold weather can be difficult.
What to check:
Poor-quality fuel or contaminated fuel can cause hard starting issues. If water, dirt, or other contaminants are present in the fuel tank, it can clog filters, corrode injectors, and even damage the engine.
What to check:
The starter motor itself can sometimes fail, causing a hard start. If the starter motor is not engaging properly or the solenoid is malfunctioning, the engine may not turn over as expected.
What to check:
To effectively troubleshoot a hard start issue, follow these steps:
Preventive maintenance is key to avoiding hard start problems in the future. Regularly inspect the fuel system, clean the battery terminals, and check the condition of the glow plugs to ensure they are operating optimally. Additionally, make sure to replace filters at regular intervals as per the manufacturer's maintenance schedule.
Conclusion
Hard start issues in the John Deere 318D can stem from a variety of causes, ranging from electrical issues to fuel system problems. By performing regular maintenance and troubleshooting the potential causes, you can keep your skid steer running smoothly and avoid unnecessary downtime. With the right tools and knowledge, you’ll be able to diagnose and fix the problem, getting your John Deere 318D back to work efficiently.
Remember, a little maintenance goes a long way in preventing hard start issues and ensuring the longevity of your equipment. Stay proactive with your maintenance schedule and take the time to address minor issues before they turn into major problems.

One of the most common culprits behind hard starts is an undercharged or faulty battery. The 318D requires a solid charge to properly turn the engine over. Over time, batteries can lose their charge or fail altogether, especially in colder months.
What to check:
- Battery voltage: Ensure the battery is fully charged and that there are no signs of corrosion around the terminals.
- Battery cables: Check for wear, corrosion, or loose connections.
- Charging system: A faulty alternator could cause an inadequate charge, leading to starting issues. It’s worth checking the alternator output.
Fuel delivery problems can also cause the John Deere 318D to have a hard start. Clogged fuel filters, air in the fuel lines, or a malfunctioning fuel pump can all disrupt the engine’s ability to get the fuel it needs to start.
What to check:
- Fuel filters: Over time, fuel filters can become clogged with dirt, rust, or debris, restricting fuel flow. Replacing the fuel filter is an easy and effective way to resolve many starting issues.
- Fuel injectors: If fuel injectors are clogged or malfunctioning, they can prevent proper fuel atomization, leading to a rough or hard start.
- Air in the fuel lines: Sometimes air can get into the fuel lines, particularly if the fuel tank is running low or there are loose connections. Bleeding the fuel system can solve this problem.
The John Deere 318D, like many diesel-powered machines, uses glow plugs to assist with starting in cold conditions. If the glow plugs are faulty or not functioning correctly, starting the engine in cold weather can be difficult.
What to check:
- Glow plugs: Check the resistance of the glow plugs to see if they are functioning properly. If one or more glow plugs are faulty, it can prevent the engine from starting efficiently.
- Relay or fuse: Sometimes the issue lies with the glow plug relay or fuse. If these components fail, the glow plugs may not heat up, making it hard to start the engine.
Poor-quality fuel or contaminated fuel can cause hard starting issues. If water, dirt, or other contaminants are present in the fuel tank, it can clog filters, corrode injectors, and even damage the engine.
What to check:
- Water in the fuel: Use a fuel water separator or drain valve to check for water accumulation in the fuel tank.
- Fuel additives: If you're operating in cold climates, consider using fuel additives that help prevent gelling or freezing of diesel fuel.
The starter motor itself can sometimes fail, causing a hard start. If the starter motor is not engaging properly or the solenoid is malfunctioning, the engine may not turn over as expected.
What to check:
- Starter motor: Listen for clicking sounds when turning the key. This could indicate a problem with the starter motor.
- Solenoid: A faulty solenoid could fail to engage the starter motor, preventing the engine from turning over. Inspect and test the solenoid for continuity.
To effectively troubleshoot a hard start issue, follow these steps:
- Inspect the Battery and Electrical System: Begin by testing the battery voltage and checking the terminals for corrosion. If necessary, clean the terminals and ensure the battery is fully charged.
- Check Fuel Filters and Fuel Delivery: Replace any clogged fuel filters and inspect the fuel system for leaks. Ensure the fuel lines are free of air and debris.
- Test Glow Plugs and Starting Aid: If you're dealing with cold weather, check the glow plugs to ensure they are operating correctly. Also, check the relay and fuse for the glow plug circuit.
- Evaluate the Starter and Solenoid: If the engine turns over slowly or not at all, inspect the starter motor and solenoid for any signs of failure.
- Examine Fuel Quality: Drain any water from the fuel tank and inspect the quality of the diesel. Add fuel additives if necessary to prevent gelling in cold conditions.
Preventive maintenance is key to avoiding hard start problems in the future. Regularly inspect the fuel system, clean the battery terminals, and check the condition of the glow plugs to ensure they are operating optimally. Additionally, make sure to replace filters at regular intervals as per the manufacturer's maintenance schedule.
