Out till 10 oclock lastnight on the old girl. Checked the heater timer relay connections, volts at the plugs and continuity checks on the wiring. Everything worked as advertised. Car started on the first turn of the key every time...admittedly the engine wasn't stone cold, but game on!!?? Or was it?
Stood at the window at 6 oclock this morning, I saw plumes of smoke and heard the clattering of a misfiring diesel. Not to mention the glare of a more than disapproving missus. Is she doing something wrong when she starts it?[}:)] Whats the deal?? Please, she's threatened to make me sell it and get a newer car. What will I do with all my spare time.
The cold stat, is working.
I've fitted Beru 909 plugs.
11.5v at pre-heat stage. (Allowing for current draw and volts drop, I think thats a good figure?)
Cranks really well, it has too!!
I've primed the pump, it made no difference.
What next?? Anyone.....
rough upon startup

Hi Francis!
I've just finished changing all four glowplugs on my '93 XM TD12. The whole procedure too 1 1/2 hours (including changing the fuel filter while I was at it and discovering that the funny smell of diesel thqat I couldn't find was due to a cracked injector return pipe where it pushes onto the pump's metal pipe).
After sussing out the engine, I decided to lift off the upper part of the intake manifold - it's only held in place by four easily accessible screws (don't forget to undo the EGR pipe from the middle of the lump). With the great lump of aluminium out of the way, all plugs are reasonably accessible - 3 directly with a deep 12 mm socket and the last one, behind the injection pump, after disconnecting the small cooling hose that is in the way (this hose by the way, cost me a head gasket replacement - so if yours looks dodgy, change it! - and order it from Citroën well in advance, it's not a stock item)- is easily removable with a ring/open 12 mm spanner.
My XM had stated to be difficult to start when it was below zero (quite common over here, even in the extreme south of Sweden) and I guest that the glowplugs wher the culprits since to my knowledge, the yhave never been replaced. The car has done over 508,000 km so thats saying something for Beru glowplugs! Sure enough, two of the plugs had given up the ghost and the difference in starting was direct.
Mind you, it's pretty back-breaking job - bending over that great lump and I had to take my gloves off - you just can't feel anything as small as the little nuts on the ends of the plugs - so your hands get reeelll dirty - injection pumps are filthy things!
Still. glad i did it now (it's a sunny day for once - so I didn't freeze!)
