About Isuzu diesel pumps

What are the signs of a faulty Isuzu fuel pump?

Warning signs of imminent Isuzu diesel fuel pump repairs are:

  • high-pitched whining or scraping sounds
  • trouble accelerating
  • spluttering or misfiring
  • low fuel pressure.

When the vehicle fails to start, or stalls on an incline or when towing a load, the engine is being starved of fuel. That’s an indication of Isuzu diesel pump problems.

What causes fuel supply problems in Isuzu vehicles?

Over time, residue can build up in the fuel system.

When enough debris collects in the system, it clogs up the fuel pump and the injector spray tip.

As a result, the injector fails to close and impacts cylinder performance.

It’s not only the pump that can cause fuel supply problems.

When the components in a fuel injector pump are defective, the timing of the fuel transfer process can be interrupted.

When this happens, a full Isuzu diesel pump refurbishment is usually required.

How does the fuel system differ across Isuzu models?

Isuzu is renowned for developing a comprehensive range of diesel engines with different fuel systems.

Over the years, the Japanese manufacturer has used Bosch PES-K and PES-A fuel pumps, direct injection units, indirect injection systems and VE-Rotary Zexel injection pumps.

The common rail injection system was introduced in the 4EE1 engine and later changed to the Bosch electronic fuel injection pump with turbochargers in the F-class of engines.

The most recent 4JA1 engine uses a high-pressure common rail direct-injection system.

How about the popular Isuzu models in South Africa?

The Isuzu KB bakkie has a direct-injector diesel fuel pump. The Isuzu D-Max and Isuzu Mu-X feature a direct-injection turbo intercooled system.

The Isuzu N-Series of trucks is fitted with a common rail turbo intercooled system.

Repair or replace a faulty Isuzu diesel pump?

The age, condition and diagnosis of a faulty Isuzu fuel pump determines whether it should be repaired or replaced.

At J.E.G. Diesel, we use advanced diagnostic testing to find the most cost-effective solution to your Isuzu diesel pump problems.

In most cases, repairing the Isuzu fuel pump to as-new condition is all that’s required.
