diagnosing diesel pump fault.

Post by extaxi »

Hi peeps,
First post and have a prob with my 406 1.9 td GLX r reg 90 bhp model.

First though i must say that my 406 has covered over 300 thou miles !!!......and all the electrics work!!! only fault is stereo display can't be read in dark!!!!

Car was fault less till last week when after travelling 25 miles home from work stalled at a junction. Started up fine and got home were stalled on drive. As the nights have drawn in i had lights on and raining had wipers etc on. So i just tweaked up the throttle cable and car was fine the next day. However fault reappeared 5 miles from work where it stall again at a junction. Fired up but was rough like it was missing. Was on tick over but would not rev atall. Eventually rev and i pulled it off the road.

I am thinking diesel pump but how do i diagnose it? Or what else could it be.? Quite handy with spanners and have tried undoing injector feed pipes and a little diesel and air. Filter is clear as well.

Any help would be greatly appreciated.

many thanks
Jon

the only fault i ever had with my xantia was the low pressure pump in the tank, it would be fine then just randomly stop working, not sure if its the same as your problem though

Welcome! I can't help with the diseasel problem, but I can help with this:

Just lever the display out from the left and right sides, unplug the socket at the back, and whip the bulb holders out from the holes in the top (may need a pair of needle-nosed pliers). Change the bulbs, shove the holders back in, plug the socket back in, and push it back into the hole.

You can get a pack of 2 bulbs from Maplins, part number N83CF for £2.

Alternatively bulbs in new holders can be bought for about £3 from your Pug dealer

does it run lumpy/rough and then stall?
more than likely the fast idle vacuum capsule or solenoid has failed, VE VP20 pumps never really go on the 406
does it knock/rattle excessivly at idle?
