FREQUENTLY ASKED QUESTIONS
Common questions about fuel pump repair
How do I know if a high-pressure pump is faulty?
Typical symptoms are difficult starting, loss of power, increased fuel consumption and fault codes in the ECU. The injector is often suspected first — a pump test on the bench rules that out or confirms it beyond doubt.
How long does the repair take?
Usually 1–2 working days from arrival to dispatch. For urgent cases we offer a 24-hour express service — please state this with your enquiry.
Is repair worthwhile instead of replacement?
In most cases yes — a professional repair costs a fraction of a new part. After the intake diagnostics you receive a clear recommendation. Where the damage is beyond repair, we advise on replacement.
Do I get a quotation?
Yes, always. After the intake diagnostics you receive a clear quotation — the repair only begins once you have approved it. If a repair is not possible, you pay the diagnostics fee only.
What happens if the pump can no longer be repaired?
If testing shows that a repair is not sensible, we inform you immediately. You pay the diagnostics fee only. On request we can advise on sourcing a replacement pump.
