I had my Honda FR-V (55 plate, around 60k miles, 2.2 diesel) serviced at an independent recently. They told me that they had had problems with replacing the fuel filter and that the car kept stalling. They suggested that I give it a long drive to ensure that the fuel is flushed through the system and that there are no air locks.
The car kept struggled to start, required me to keep squeezing the fuel bulb under the bonnet, and then kept stalling. I did manage to drive it for 40 miles on one day and thought that the problem was solved, but it then reoccured the following day.

I took it to the local official Honda garage and asked them to investigate. They have come back and said that the fuel pump needs to be replaced at a cost of GBP 1,900 (plus three hours of labour at GBP 85 per hour). This seems to be a very high cost to replace a fuel pump! Also, why would the fuel pump have failed, and what could have caused it? Could the independent have caused the problem (not installed the fuel filter correctly and the pump having to work too hard to circulate the fuel?). Could "replacement of fuel pump" be a lazy diagnosis? Is the fuel pump failing a known fault in the Honda diesel system?
Any advice appreciated. Thanks.
