• Intermittent or complete no-start conditions
• Engine stalling, especially when warm Loss of fuel pressure leading to hesitation or uneven running
• Electrical overheating or relay chatter Fuel pump running continuously - a significant safety risk
Replacing the relay restores reliable fuel delivery and ensures the fuel pump operates exactly as Porsche intended.
