John Deere 328 Skid Steer No-Start Diagnosis and Field Solutions

[MikePhua]

The Legacy of the Deere 328 Skid Steer
John Deere entered the skid steer market in the late 1990s, aiming to compete with Bobcat and Case in compact equipment. The 328 model, introduced in the mid-2000s, was part of Deere’s 300 Series—a lineup known for robust frames, high hydraulic flow, and operator-friendly controls. With a rated operating capacity of over 2,800 lbs and a turbocharged diesel engine producing around 85 horsepower, the 328 was built for demanding tasks like grading, material handling, and demolition.
By 2006, the Deere 328 had gained traction in North America, especially among contractors who valued its vertical lift geometry and strong breakout force. However, like many machines of its era, electrical and fuel system issues could surface over time, especially in high-hour units or those exposed to harsh conditions.
Symptoms of a No-Start Condition
When a John Deere 328 refuses to start, the issue can stem from multiple systems. Common symptoms include:

• Engine cranks but does not fire
  
• No crank at all when key is turned
  
• Clicking sound from starter relay
  
• Dashboard lights flicker or remain off
  
• Fuel pump silent during key-on
  

Terminology notes:

• Crank: The rotation of the engine’s crankshaft initiated by the starter motor.
  
• Starter relay: An electrical switch that sends power from the battery to the starter motor.
  
• Fuel pump prime: The initial pressurization of the fuel system when the ignition is turned on.
  

In Alberta, a contractor experienced a no-start after a rainy week. The culprit was a corroded ground strap near the battery tray, which interrupted the starter circuit.
Electrical System Inspection and Common Faults
The Deere 328’s electrical system includes:

• Battery and ground cables
  
• Ignition switch and safety interlocks
  
• Starter motor and solenoid
  
• ECM (engine control module)
  
• Fuses and relays in the main panel
  

Troubleshooting checklist:

• Test battery voltage (should be 12.6V or higher)
  
• Check ground connections for corrosion or looseness
  
• Inspect starter solenoid for continuity
  
• Verify fuse integrity with a multimeter
  
• Bypass ignition switch to test starter response
  

In Georgia, a fleet manager added dielectric grease to all harness connectors after repeated no-starts. This reduced moisture intrusion and improved reliability during wet seasons.
Fuel System and Injector Control
The Deere 328 uses a high-pressure common rail fuel system with electronic injectors. If the engine cranks but doesn’t fire, fuel delivery is a prime suspect.
Inspection points:

• Listen for fuel pump during key-on
  
• Check fuel filter for clogging or water
  
• Inspect injector harness for damage
  
• Test fuel rail pressure with diagnostic tool
  
• Bleed air from lines after filter replacement
  

Terminology notes:

• Common rail: A shared high-pressure fuel line feeding all injectors.
  
• Bleeding: The process of removing air from fuel lines to restore pressure and flow.
  

In Chile, a contractor replaced his fuel filter with an aftermarket unit that lacked proper sealing. Air entered the system, causing hard starts until the OEM filter was reinstalled.
Safety Interlocks and Operator Presence System
The Deere 328 includes several safety features that prevent starting unless conditions are met:

• Seat switch detects operator presence
  
• Park brake must be engaged
  
• Boom and bucket must be in neutral
  
• Door or lap bar must be closed (on enclosed cab models)
  

Failure of any sensor or switch can interrupt the start sequence.
Solutions:

• Test seat switch continuity
  
• Inspect park brake switch for wear
  
• Check boom and bucket position sensors
  
• Bypass interlocks temporarily for diagnosis
  
• Replace worn switches with sealed replacements
  

In Florida, a contractor discovered that his seat switch had collapsed internally. Replacing it restored full start functionality and eliminated intermittent faults.
Starter Motor and Solenoid Wear
If the engine doesn’t crank, the starter motor or solenoid may be at fault. Symptoms include:

• Single click with no rotation
  
• Heat buildup near starter housing
  
• Burnt smell or visible arcing
  
• Inconsistent response to key turns
  

Recommended actions:

• Tap starter housing lightly to free stuck brushes
  
• Test solenoid voltage during crank
  
• Replace starter if resistance exceeds spec
  
• Use high-quality remanufactured units for longevity
  

In New Zealand, a snow-clearing crew replaced their starter with a marine-grade unit. The improved sealing and corrosion resistance extended service life by 40%.
Preventive Maintenance and Long-Term Solutions
To avoid future no-start issues:

• Clean battery terminals monthly
  
• Replace fuel filters every 250 hours
  
• Inspect wiring harnesses for abrasion
  
• Use sealed relays and connectors in wet environments
  
• Keep diagnostic codes logged for trend analysis
  

In South Africa, a contractor added a solar trickle charger to maintain battery health during seasonal downtime. This reduced no-start complaints and improved cold-weather reliability.
Parts Availability and Sourcing Tips
John Deere parts are widely available through:

• OEM dealers and service centers
  
• Aftermarket suppliers offering electrical and fuel components
  
• Salvage yards with 300 Series inventory
  
• Specialty shops for sealed switches and marine-grade starters
  

Sourcing tips:

• Use serial number to match engine and electrical components
  
• Cross-reference relays and sensors with industrial equivalents
  
• Seek remanufactured starters with warranty support
  

In Tennessee, a contractor rebuilt his starter using parts from a retired generator. The retrofit required minor machining but restored full functionality.
Conclusion
A no-start condition in a John Deere 328 skid steer can stem from electrical faults, fuel delivery issues, or safety interlock failures. With structured diagnostics, quality parts, and preventive strategies, operators can restore reliability and avoid costly downtime. Whether grading driveways or loading debris, the 328 proves that even compact machines demand respect—and reward those who understand their systems.
