Injection Pump
On mechanically timed diesel systems, the pump itself decides delivery quantity and timing under electronic control. Expensive enough that confirming the fault properly before replacement is worth real money — a blocked filter or weak lift pump makes a healthy pump look worn.
Also known as: diesel pump, ip, vp44, distributor pump, rotary pump, ve pump, injector pump

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

Nothing posted about this yet. Whatever you found is worth writing down — even a dead end saves someone the same afternoon.
What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
