Car came in with jumping/momentary power loss at speed under power.
Removed injectors and had them checked. they were ok. Refitted them and then had loss of power even when stationary. takes time to build up revs.Poor starting.
Had injectors re checked, still the same

Removed pump and sent away, £850 later it was reffitted. Starting now fine but still severe lack of power.

Re-checked timing,ran from can without using fuel line, blocked egr pipe,had injectors checked again by different company still lack of power.

Im running out of ideas any help welcome.
