• Faulty fuel injector control module.
  
• Shorted or damaged wiring in the injector control circuit.
  
• Corroded or loose connectors.
  
• Malfunctioning fuel injectors.
  
• ECM failure to process injector signals.
  
  

How to Fix It:

1. Inspect wiring and connectors for damage.
   
2. Test the fuel injector control module for functionality.
   
3. Replace damaged or corroded connectors.
   
4. Replace the faulty injector control module if necessary.
   
5. Monitor injector performance via diagnostic tools.
   
   

How to Avoid It Before It Happens:

• Regularly inspect fuel system components.
  
• Monitor injector control performance with diagnostics.
  
• Replace fuel injectors as necessary.
  
• Clue’s fuel management services track injector performance and prevent fuel delivery issues before they cause engine problems.
