Rebuilding a diesel injection pump typically costs £300 to £900, depending on the pump type, parts required, and labour involved. High-pressure common-rail pumps may cost more.

How to tell if a diesel injection pump is bad?

Common signs include hard starting, rough idle, loss of power, excessive smoke, poor fuel economy, and engine misfires. A diagnostic test confirms whether the pump is failing.
