Some jobs look simple on paper. This one wasn’t.

We recently completed a very challenging fuel pump replacement on a Peugeot 3008 that came in with intermittent starting issues, loss of power under load and occasional engine cut-outs.

The Symptoms

The customer reported:

• Long cranking before the engine started
• Engine cutting out while driving
• Reduced power when accelerating
• Engine management light appearing randomly

Initial scans showed low fuel pressure faults, but the issue was not consistent — which made diagnosis more complex.

The Challenge

On this 3008 (diesel model), access to the fuel system components was restricted and required careful disassembly.

What made it difficult:

• Inconsistent fuel pressure readings
• Contamination in the fuel system
• Additional strain on the high-pressure pump
• Limited access requiring removal of surrounding components

Before replacing parts, we carried out:

• Full fuel pressure testing
• Live data diagnostics
• Injector return flow checks
• Electrical supply testing to the pump

We never replace major components without confirming the root cause.

The Repair

After confirming internal pump failure, we:

• Replaced the faulty fuel pump
• Flushed the fuel system
• Replaced fuel filter
• Cleared fault codes
• Road tested under load conditions

The vehicle now starts instantly and fuel pressure remains stable across all driving conditions.

Why Proper Diagnosis Matters

Fuel system repairs can become very expensive if misdiagnosed. On modern vehicles like the Peugeot 3008, replacing the wrong component can cost thousands.

At Pit-Air Motors in Croydon, we focus on:

• Accurate diagnostics
• Honest communication
• Fixing the actual problem — not guessing

If your Peugeot 3008 is suffering from starting issues, loss of power or fuel pressure faults, contact us for a proper inspection.
