The Ford 555D is a well-regarded backhoe loader known for its reliability and versatility in construction, agriculture, and landscaping applications. However, like any machinery, it’s not without its challenges. One common issue that operators may encounter is intermittent starting problems, where the machine may start fine one moment, and then fail to start the next. This can be frustrating, especially when you’re on a tight schedule. In this article, we’ll explore potential causes of the Ford 555D's intermittent starting issue and provide troubleshooting solutions to help resolve the problem.
Understanding the Problem
An intermittent starting issue can often be related to several factors, ranging from electrical problems to fuel system issues. Given that the Ford 555D is equipped with both diesel and electrical components, diagnosing the cause of the problem requires a systematic approach to rule out the various possible culprits.
In many cases, the issue might not be consistent, making it harder to pinpoint the exact cause. While the machine may start without problems on some days, on others, it may struggle to turn over or not start at all. Such issues are often linked to the following areas:
Here’s a step-by-step guide to diagnosing and fixing intermittent starting issues with the Ford 555D:
1. Check the Battery and Charging System
A weak battery or charging system failure is one of the most common causes of intermittent starting problems. If the battery is old or not holding a charge, it may not provide enough power to engage the starter motor.
A faulty starter motor can lead to intermittent starting problems. If the starter motor isn’t engaging properly, the engine may not turn over.
If the starter motor and battery check out, the issue may lie within the ignition switch or relay. The ignition switch sends power to the starter motor when the key is turned, and the relay helps complete the circuit.
Problems with the fuel system can also lead to starting issues, particularly if there is a lack of fuel pressure or air in the fuel lines.
Loose or corroded electrical connections can lead to intermittent problems, especially if the machine has been exposed to harsh weather or heavy use.
If you’ve gone through these troubleshooting steps and the problem persists, it may be time to consult a professional mechanic or technician. Intermittent electrical issues can sometimes be difficult to diagnose, especially if they involve complex components such as the ignition system or fuel delivery system.
Professional mechanics have the tools and experience to pinpoint the problem quickly and efficiently, saving you time and money in the long run. Additionally, a qualified technician can inspect other components of the machine to ensure it’s running in optimal condition.
Conclusion
Intermittent starting issues on the Ford 555D backhoe loader can be caused by a variety of factors, ranging from simple electrical problems to more complex issues in the fuel or ignition systems. By systematically checking the battery, starter motor, ignition switch, fuel system, and wiring, you can often identify the root cause of the problem. Regular maintenance and early detection of issues can help extend the lifespan of your Ford 555D and reduce the likelihood of unexpected downtime. When in doubt, seeking professional help is always a reliable option to ensure your machine stays in good working condition.

An intermittent starting issue can often be related to several factors, ranging from electrical problems to fuel system issues. Given that the Ford 555D is equipped with both diesel and electrical components, diagnosing the cause of the problem requires a systematic approach to rule out the various possible culprits.
In many cases, the issue might not be consistent, making it harder to pinpoint the exact cause. While the machine may start without problems on some days, on others, it may struggle to turn over or not start at all. Such issues are often linked to the following areas:
- Battery and Charging System: A weak or failing battery, a malfunctioning alternator, or poor battery connections can prevent the engine from starting properly.
- Starter Motor: A worn-out or failing starter motor might struggle to engage, causing inconsistent starts.
- Ignition Switch or Relay: A faulty ignition switch or relay could prevent the electrical system from sending the proper signals to the starter motor.
- Fuel Delivery System: Problems within the fuel system, such as clogged filters, air in the fuel lines, or an issue with the fuel pump, can lead to intermittent starting problems.
- Electrical Wiring and Connections: Loose or corroded wiring can create inconsistent electrical connections, resulting in failure to start.
Here’s a step-by-step guide to diagnosing and fixing intermittent starting issues with the Ford 555D:
1. Check the Battery and Charging System
A weak battery or charging system failure is one of the most common causes of intermittent starting problems. If the battery is old or not holding a charge, it may not provide enough power to engage the starter motor.
- Test the Battery: Use a multimeter to check the battery voltage. A healthy 12-volt battery should read around 12.6 volts when the engine is off. If the voltage is below 12 volts, it might indicate that the battery is weak or failing.
- Inspect the Charging System: While the engine is running, check the voltage at the battery terminals. It should read between 13.7 and 14.7 volts. If it’s lower than that, the alternator may not be charging the battery properly, which could explain the intermittent starting issue.
- Examine Battery Terminals: Corroded or loose battery terminals can prevent proper electrical flow. Clean the terminals and ensure they’re tight.
A faulty starter motor can lead to intermittent starting problems. If the starter motor isn’t engaging properly, the engine may not turn over.
- Listen for Clicking Sounds: When you turn the key to start, listen for any clicking or grinding noises. A single click may indicate a faulty starter solenoid, while continuous clicking could point to a weak battery.
- Test the Starter Motor: If the battery and wiring seem fine, you may need to test the starter motor itself. You can either bench test the motor or remove it and have it tested at an auto parts store.
- Examine Starter Wiring: Check for loose or corroded wires going to the starter. Any issues with the wiring could prevent the starter motor from receiving enough power.
If the starter motor and battery check out, the issue may lie within the ignition switch or relay. The ignition switch sends power to the starter motor when the key is turned, and the relay helps complete the circuit.
- Test the Ignition Switch: A malfunctioning ignition switch can prevent power from reaching the starter motor. Use a multimeter to check for continuity when the switch is turned to the "start" position.
- Inspect the Starter Relay: The starter relay controls the flow of electricity to the starter motor. If the relay is faulty, it may cause intermittent starting issues. Try swapping the relay with another one of the same type and see if the issue persists.
Problems with the fuel system can also lead to starting issues, particularly if there is a lack of fuel pressure or air in the fuel lines.
- Check Fuel Filters: Clogged fuel filters can restrict fuel flow to the engine, causing hard starting or no-start conditions. Replace the fuel filters if they appear dirty or clogged.
- Inspect the Fuel Lines: Look for leaks or cracks in the fuel lines. Air in the fuel system can cause difficulty starting the engine.
- Test the Fuel Pump: A failing fuel pump may not provide enough pressure to get fuel to the engine. Check the fuel pressure and replace the fuel pump if necessary.
Loose or corroded electrical connections can lead to intermittent problems, especially if the machine has been exposed to harsh weather or heavy use.
- Check for Loose Wires: Inspect the wiring harness for any loose or disconnected wires. Pay particular attention to the connections at the starter motor, ignition switch, and alternator.
- Examine for Corrosion: Corrosion on wiring terminals can interrupt electrical flow. Clean any corroded connections with a wire brush and apply dielectric grease to prevent future corrosion.
If you’ve gone through these troubleshooting steps and the problem persists, it may be time to consult a professional mechanic or technician. Intermittent electrical issues can sometimes be difficult to diagnose, especially if they involve complex components such as the ignition system or fuel delivery system.
