Meta Mechanics recently completed a comprehensive repair service for a Range Rover SV that experienced engine stoppage while driving. Our expert team identified several issues that were causing the engine to unexpectedly shut off. Here are the key issues we discovered and the solutions we provided to resolve them:
Issue Found:
- Faulty Fuel Pump
- Issue: The fuel pump was malfunctioning, leading to insufficient fuel supply to the engine, causing it to stall and stop while driving.
- Solution: We replaced the faulty fuel pump with a high-quality replacement, ensuring consistent fuel delivery and preventing future engine stoppage issues.
- Clogged Fuel Filter
- Issue: The fuel filter was clogged with debris, restricting the flow of fuel to the engine, which resulted in the engine running lean and stalling intermittently.
- Solution: We replaced the clogged fuel filter, ensuring that clean fuel reaches the engine, improving fuel efficiency and preventing stalling during driving.
- Ignition System Failure
- Issue: The ignition system was found to have faulty spark plugs and ignition coils, leading to misfires and incomplete combustion, which caused the engine to cut off unexpectedly.
- Solution: We replaced the faulty spark plugs and ignition coils, restoring proper ignition timing and ensuring smooth engine operation without misfires.
- Malfunctioning Crankshaft Position Sensor
- Issue: The crankshaft position sensor was damaged, causing inaccurate readings of the engine’s position, which led to the engine losing synchronization and shutting down.
- Solution: We replaced the malfunctioning crankshaft position sensor, ensuring accurate data is sent to the engine control unit (ECU), preventing engine stalls and ensuring proper engine timing.
- Electrical System Issues
- Issue: A weak battery and corroded electrical connections were causing intermittent power loss, leading to the engine cutting off while driving.
- Solution: We replaced the old battery and cleaned the electrical connections to restore consistent power supply to the engine and all critical components, preventing any further electrical-related engine shutdowns.
