The car cranked, but wouldn't start this morning for my wife (no problems when parked up last night). I spoke to her on the phone, and she tried key on/key off a few times to get the glow plugs really hot, and the engine caught for a second then died. A bit of white smoke came out of the exhaust. When I get home I will check the supply to the glow plugs.
Any other ideas?

hisounds like air in the fuel system tomorrow morning try pumping the primer, then try starting.
If car then works then this is your problem, and you then have to find the leak. Dont keep cranking the engine, the pump is not designed to pump air and the lack of fuel will cause it damage and they are expencive !, as
these pumps use the fuel as both lubricant and cooling. Al

Thanks Al,I did try this when cranking yersterday, but it didn't help. I also checked that there was power to the glow plugs, and that there is clean fuel (it got filled up the day before - receipt states diesel).
I pulled the filter cover off and there was plenty of diesel.
The engine did fire without priming, but it had a harsh diesel crack, and ran for 1-2 secs, with a puff of grey smoke. I don't like extended cranking when it is like this.
I also noticed the alternator belt has jumped a groove and started to wear on the inside edge. This appears to have only just happened. I removed it and only one small cord is stripped, but I am now taking off the cambelt covers to make sure that the timing is ok. It cranks as if there is compression and no mechanical knocking, but it may be that the fuel pump has jumped a tooth.
I don't coincidences. I haven't cranked it for long for the very reason that it could cause further damage.

hiOK ......... two things here first
you say you have power to the heater plugs, but have you actually removed them and tested them ? un like a spark plug on a petrol engine, which can have a weak spark etc the heater plugs are a more like a bulb, they either work or dont, so just having power to them don't mean they work. second
the aux belt, change it ! on this engine they have a nasty habit if they break they can get up inside the cam belt cover and cause the cam belt to jump with disasterous consequences ! Al

I've found the fault - the aux belt stripped a cord and the cambelt jumped a tooth on the crank pulley. The cam and pump are timed together but one tooth out from the crank.
Fortunately no touching when turned over by hand. The aux belt tensioner pivot bolt is worn, tilting the pulley inwards, pushing the belt into the cambelt cover.
Tonight's job - getting the bottom pulley bolt off...
At least all the parts are in stock.
Will also check glow plugs are ok with all intake pipes now out the way.
Any ideas of the best way to remove the auto tensioner for the aux belt? There is a huge spring fitted against the LHM pump bracket. I don't want to release the spring then not be able to get it back on.

Car is now fixed - new cambelt, aux belt and tensioner.
After fitting the new cambelt and correcting the timing, the engine fired up on the button. It actually starts better than before.
I didn't break, lose or injury anything, so that was a winner.
The faulty part? The aux belt tensioner bush corroded, gone out of centre and twisted the pulley.

Higlad your sorted, had simmilar (Pug 306 td )when my tensioner went out of line my shreaded belt went up under the cam belt cover took the pump out by few teeth, lucky the cam & crank stayed in line, it did however take a chunk out of the cam belt so replaced it as well. That big spring on the tensioner was a pain and I still have a resonating sound at idle speed as its ocilating, got to find time (and dry weather!) to re adjust it. Al

Hi Al,Maybe (I know it's sad) I'll get round to take some photos. If it will help someone else on this forum in the future.
I found something interesting on the aux tensioner - there are 2 of them. One, with the big spring on it on the LHM pump bracket, and the other, a manual, eccentric one lower down. Strangely enough, with the tensioner released, there is no spring tension at all - I could just undo the spring and it fell off. Made it a whole lot easier to take the tensioner off.
I don't know how it works on the Pug because you don't have the same hydraulic pump.
I found that with the belt on, by turning the manual, eccentric pulley clockwise, this put tension on the top, auto tensioner until the holding peg lined up. This helps with getting the right tension and also with getting the belt off for servicing/repair.
Mine chattered before the failure, and I just put it down to mileage. Now I know why it was chattering...
The other interesting thing is that the belt comes in different lengths depending on the a/c compressor fitted (if you have a/c).
I've now started making a list of the other maintenance jobs to get round to before next year's MOT...it never stops :-) Dave.
