Hi
Disco 2 - 180k miles. I had a problem starting, with fuel pump making strange burbling noise. After starting it ran fine. Mechanic diagnosed 'knackered' pump which was replaced. Within a couple of weeks the starting problem returned - plus a new one, engine cutting out after 5 miles, and 2/3 minutes wait before the fuel pump kicked in and after constant cranking would restart.
Garage diagnosed 'duff fuel pump' (it was a 'compatible' pump) and recc LR fuel pump. This has been fitted - but hasn't cured the problem.
Some oil in the loom but mechanic says not sufficient to be a problem. He's also checked that all the pipes are on right, not kinked. He has checked fuel flow and that the ECM is sending out all the right signals
The car was running fine before the fuel pump was changed, so could something have been dislodged in fitting - or could a new pump put too much pressure on another (ageing) component Fuel regulator? Fuel Filter?
UPDATE... Monday 28 January -
Fuel injector seals have been changed and vehicle now appears OK. One was definitely showing signs of leakage and two more were 'possible'.
BUT it still baffles me WHY... there was no cutting out before pump was changed. Did the increased flow or pressure finish off already dodgy seals? My guys spoke to LR mechanics and other 4x4 specialists - all say 'no - they must have always been faulty' - but if so why did it not cut out or run rough until we changed the pump?.
