What goes wrong

The electronically controlled injection pump on the direct-injection ZD30 is a well documented failure point. The pump runs hot and its internal electronics and metering components wear, causing hard starting, stalling and eventually a no-start. Reconditioned pumps are expensive and fitting/coding adds labour. Diesel specialists recommend clean fuel and filter changes on schedule; some owners fit a lift pump to reduce pump load and heat.

What you would notice

  • Hard starting, especially when hot
  • Intermittent stalling then restarting once cooled
  • Engine cutting out at speed
  • Check-engine light with fuel pump / injection codes

How to check it

Where to look. Injection pump on the side of the 3.0 diesel engine, driven off the timing gears

  1. Start the van from stone cold, then again after a decent hot drive - hot-start hesitation is the classic early sign.

  2. Ask a diesel shop to read fault codes before purchase.

  3. Check the fuel filter service history; contaminated fuel kills these pumps.

Parts involved: Fuel injector.

What it costs to put right

$2,500 to $4,500 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

  • “Has the injector pump ever been replaced or reconditioned - is there a receipt?”
  • “How often has the fuel filter been changed?”
  • “Does it ever stall or refuse to start when hot?”

What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today.
