Known Ford Courier (pre-2006) faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
The Bosch CP4.1 high-pressure injection pump fitted to the P4AT 2.0 EcoBlue engine can catastrophically disintegrate internally, sending hard metal debris at high pressure throughout the entire fuel rail, injectors, low-pressure lines, and fuel tank. Because the contamination is systemic, partial repair is not viable — the complete fuel system must be replaced. The failure is linked to the pump's tight internal tolerances and sensitivity to ultra-low-sulphur diesel's reduced lubricity, which is standard fuel in New Zealand and Australia.
Symptoms to notice
Hard start or extended cranking before the engine fires
Rough idle with injector ticking becoming uneven
Power loss or engine stalling under acceleration load
Metal shavings or black residue visible in the fuel filter bowl
Complete sudden engine failure with no restart possible
What to check
Check for any history of hard start, long crank times, or engine stalling under load — early warning signs before full pump failure. Request fuel system service records and ask if the vehicle has ever consumed any fuel additives. Listen at idle for uneven injector ticking or misfiring. On PX3 Rangers with high kilometres (above 80,000 km) and no pump replacement history, treat this as a latent risk.
Where to look: High-pressure fuel pump mounted on top of the engine block, driven off the camshaft
Ask the seller
“Has the high-pressure fuel pump or any fuel injectors ever been replaced, and do you have the workshop invoice?”
“Has the vehicle ever had difficulty starting, lost power on the highway, or been diagnosed with fuel system contamination?”
“Has a pre-purchase mechanical inspection specifically checked the fuel filter bowl for metal particulates?”
The Mazda-sourced WL 2.5L diesel (shared with Mazda BT-50) suffers from injector O-ring degradation leading to external fuel weeping or leaking around the injector body. Heat cycling accelerates O-ring hardening and cracking. Documented across AU and NZ workshops and BT-50 owner communities as a consistent age-related failure on both the Ranger and its platform-mate BT-50.
Symptoms to notice
Diesel smell in engine bay
Visible fuel staining or wet residue around injector bodies
Minor unexplained fuel economy drop
Fuel mist visible on top of engine after driving
What to check
With engine warm, inspect around each injector base for wet fuel residue or brown staining. Check for diesel odour from the engine bay after a drive. A UV dye test can confirm leak origin.
Where to look: Top of engine, injector body-to-cylinder-head mating face
Ask the seller
“Have the injector O-rings ever been replaced?”
“Any diesel smell noticed while driving or after parking?”
“Has the engine bay been steam cleaned recently?”
