Diesel Pump replacement?

Post by SethY »

Following my previous thread about the extremely clattery running diesel, the chap at the garage is pretty sure that it’s the fuel pump solenoid (?) that’s broken. It’s a bosch pump and he says thet the solenoid is integral to the pump, so I’ll need a new pump. He recons about £300 for the part then about 5 hours labour making it about £500 to replace the Fuel injector pump. That’s got to be getting on for what the car is worth, so does anyone have any experience of changing fuel pumps on diesel Xantias? Is it something that a DIYer can do? The car is a 1997 Xantia LX with Air Con.

I am not sure about fitting them, I am sure there are some here who can shed light on that, but why not fit a 2nd hand one? Sod paying £300 for one I'll sell you a working one for less than a sixth of that with postage (send me an email)!!! I would think fitting one is not too tricky and would require a wee bit of adjustment.

Not too bad a job on the Xantia, might as well get the cambelt done at the same time, if you find the same type of pump in the breakers it should swap over completely? you may need to mess around with the electricals a little, if you fit an earlier type without the immobiliser bit it should also be straightforward, set up the indexing as you would to replace the cambelt, remove old pump, refit the new one, you may need to adjust the timing on the slotted pump mounting holes but initially align the new pump on the dirty mark left by the old one and see how it runs, you may be lucky, a reasonable DIY option, there are thousands of suitable pumps in breakers yards, good luck, go for it.

There are many small diesel specialists around - may be worth having a word with one or two as I'm sure you're not the first with this problem and they may be able to replace the solenoid itself at a reasonable price.

Yes that will teach me to read the posts properly, I can see the stop solenoid on my older type bosch pump, looks easily accessible, dont suppose its the stop one though, that would manifest itself by either not stopping or possibly not starting. If its the later pump with more electonics in it arent ther threds on this forum where replacement of number three injector (the one with a power lead) cures bad running?

Yes thats right Stewart but that one had blown the ECU due to a faulty earth. In fact it looked as though the ECU could have been soldered as it had been designed with a weak point in the main track to save its life should it be subjected to gross overload.
I'll try and find the link but this may be a pump rather than ECU fault which is why I didn't mention it.
