(94 L) 1.4 diesel Fuel Pump - sparky29
My fuel pump has packed in (£105 to get recovered off the motorway - ouch!!) The car was a good runner previously sailing through the MOT every year so I am reluctant to scrap it.

How big a job is it to change the fuel pump (mechanical drive - not electric), and the cam belt at the same time, as I can't get any mechanics to change the pump with a second hand scrap yard one? They will only fit new parts. One mechanic told me that I needed a diesel specialist as it needs setting up but another told me that is rubbish but he won't do it. The diesel speciallist said it would cost £100 to diagnose that the fuel pump is broken which I have done already and £500 (the value of the car!!) to fit a recon pump.

Thanks in advance for any help/ advice

So exactly what has failed on this [Lucas?] pump?

You could maybe fit it yourself with a Haynes manual[?] and then get it timed by a specialist.

Changing the pump and cambelt is a relatively straightforward job on this car as long as you change the pump like for like by maker (strongly advised).

After fitting the pump you will need to have the injection timing set which requires a dial gauge and fixture if it's a CAV Lucas pump. If everything is carefully done, it should be possible to get the engine running well enough after a pump change to drive it to a diesel specialist to have the timing reset.

Change the most inaccessible glowplug and the rubber spill pipes whilst you're in there and fit a new fuel filter when you have finished after the final test run.

Thanks for your replies.

I don't know what type of pump it is. I've been told that it is the same as a Saxo.

I don't know what exactly has gone wrong with the pump. If I remove the fuel cut off solenoid and pump the primer ball the diesel spills out as expected. If I crack off the injectors there is no fuel getting through when I turn the engine over (with the fuel solenoid plunger removed). I have removed the cam belt cover and everything is turning OK. I presume it is something wrong internally on the pump. The failure was a sudden complete loss of engine power as I was accelerating onto the motorway (ie engine was dead)

If it is not a major job I will give it a go. Can these pumps be reconditioned or is it a job for the experts?
