What is injector EJDR00301Z?
EJDR00301Z is a Delphi common rail solenoid injector diesel injector for the Ford 2.0 / 2.4 TDCi Duratorq (FMBA / N7BA). It is supplied remanufactured, bench-tested and calibrated to OEM specification.
Which vehicles use EJDR00301Z?
It is fitted to the Ford 2.0 / 2.4 TDCi Duratorq (FMBA / N7BA) — including Ford Mondeo III 2.0 TDCi (FMBA/FMBB); Ford Transit (Mk6/Mk7) 2.4 TDCi (N7BA/N7BB); Jaguar X-Type 2.0 D (FMBA); Ford Transit (2.0 TDCi) 2.0 TDCi (FMBA). Confirm fitment by OE number and engine code.
What type of injector is EJDR00301Z?
It is a Delphi Common Rail Solenoid Injector. Always confirm the OEM markings on the injector body before fitting.
Does EJDR00301Z need coding when fitted?
It depends on the application — early Ford Duratorq common rail is often fitted without coding, but later builds may require it. Verify in Ford IDS before road test.
What are the symptoms of a failing EJDR00301Z?
Common signs are rough idle and vibration, hard starting, power loss or limp mode, black smoke and an engine-management light.
What causes these injectors to fail?
Most failures come from poor fuel filtration, contamination and water in the fuel leading to wear, high back-leakage and nozzle coking. Fix the cause before fitting replacements.
Is a remanufactured EJDR00301Z as good as new?
A properly remanufactured injector is stripped, fitted with new wear parts, reassembled and recalibrated on a common-rail test bench to OEM tolerances, then supplied with a warranty.
Should I replace one injector or the full set?
Replace the confirmed faulty injector first. On high-mileage engines fitting a matched set reduces the chance of a repeat fault, but it is not mandatory if the others test within spec.
Do you bench-test the injector before dispatch?
Yes. Every unit is tested for delivery, back-leakage and spray pattern on a calibrated common-rail tester before it leaves us.
Is delivery and warranty included?
Yes — the price includes free UK delivery and a 12-month warranty.
Does EJDR00301Z fit the Jaguar X-Type 2.0 D?
Yes — the Jaguar X-Type 2.0 D shares the Ford Duratorq FMBA engine and this Delphi injector. Confirm the Ford service number 2S7Q-9K546-AJ stamped on your part.
Does this Ford Duratorq injector need coding?
Many early Duratorq common-rail applications run without injector coding, but later builds may require it. Verify the requirement in Ford IDS for your VIN before road test.
