cold start probs

hi, my old gsdi seems to be getting harder to start in the mornings.. it was fine, but over the last few weeks, has been gradually getting worse. this mornng i had to heat it three times and turn the engine over for a good ten seconds before it fired up. theres no loss of power and it starts fine during the day once it has been started in the morning.

im using a rover ron box and increased boost (doesnt make any difference if i turn the fueling up or down).

does the car have some sort of cold start valve or the like?
any ideas would be welcome?..

thanks guys.

james.

I don't recognise gsdi, is it L series or XUD? If this is the Peugeot XUD engine (1.7 turbo or 1.9 NA), they are very glow plug dependent, even in warm weather.

If only two glow plugs working, starting becomes very difficult. My experience is based on my 218 SLD.

EDIT

Sorry its L series looking at the date of your car (silly me) I would be looking for air leaks in the fuel line. The L series does not need glow plugs in this weather.

Agree with the above posts, either timing or air.Does yours have the hand pump near the filter?.If yes try squeezing that to make sure its hard,then start it.I just had my fuel pump belt changed and it wasn't timed right,my god you should have seen the clouds of unburnt fuel coming out of the exhaust,took a good 15 seconds of cranking to start,reset the timing and she starts better than before ,on the second revolution of the engine.Also i once had leaking fuel return pipes (even though they were only 6months old!) and this caused it to start on about the 8-9th revolution then it would be rough for a minute or so,worth checking.

Pump the priming bulb till you get bored or it goes hard before you try starting in the morning. If starting improves then you have found the fault.

If not then check glow plug relay is working as they sometimes burn out but they shouldn't really be needed in the current temps.

thanks for the responses chaps.. when i left work, i checked the priming bulb, it was not rock hard, but there was fluid in it, but i pumped it anyway till it became hard (and the priming bulb too!).
i then gave her a start, but was the same, maybee five seconds till she started.

ill check the pump timing/and belt next..

thanks.

The priming bulb would only ever be hard, if you've just pumped it up :p

If you leave it for a few hours, or if you've driven the car, it'll go soft again - it's a one-way valve, so once you've "pressurised" the fuel filter, and the pipe to the pump, it'll go hard.

The second you start the engine, the fuel will be sucked into the pump, and it will all be at (almost) atmospheric pressure.


No fuel will go into the pump, apart from at an extremely slow rate - and it certainly NEVER affects the high pressure lines, the priming bulb is just that - a priming bulb

just FYI :)



Whip the battery clamp off, shove it to the side. Two 8mm bolts hold the airbox on, and the MAF sensor is only held on with a jubilee clip.
After that, it's a few 8mm bolts that hold the cover on.

On the long stretch, you should be able to twist the belt to 45degrees, but generally not much (if any) more

If the timing is out or not you won't tell by the tension on the pump belt. You need to time the engine up and see if you can slide the timing pin into the pump pulley to tell.

I'd say it could be the glow plugs. From my own experience I jumped in one morning last weekend and started the engine or at least tried to. I then allowed the glowplugs to click off properly before trying again. So even in this supposed summer the evenings are cold enough for us to need a bit of heat to start.
