Afternoon all,

My 205 D Turbo's been parked up for a while waiting for me to change the cam belt - it was running fine before laying up.

Finally got everything back together & started her up today; problem is she won't run/idle without a foot on the accelerator.

I didn't touch the injection/ignition systems except to wipe the glowplugs.

Bled the fuel filter just in case, now turns over for some time then fires up if I have my foot on the throttle, runs but with a few "missing" beats.

As soon as I let off the throttle she stalls instantly.

Any thoughts or advice welcome!

I dunno if these have the same electricals as the GTi models, but I remeber something similar happening to my 1900GTi.

Basically me and a mate had been faffing around under the bonnet and something had simply come loose. Was an electrical plug (almost like a scart socket) situated under and around the passenger strut. Just a loose connection, but contained several wires etc.

I would just check every electrical connection for being loose or moist? A common trait I have heard. Sorry I can't be of more help.

Cheers c-o-b, I had a similar thought and went back over the connectors that I could see - they seem ok.

Had my g/f sit in the car keeping it running whilst I faffed around with the idle speed contols and can get it to idle when hot, but if I try it from cold it starts then stalls immediately - aagh!

Have you knocked the coolant temp sensor? they drop into "warm engine" mode, ie struggles to run when cold but ok when hot, probably your best bet

Double check the timing.

I had a 106 diesel I bought for peanuts that needed a load of work. My dad came round to have a look, giave it loadsa revs and it jumped a tooth on the timing. Ran like pants after that..

New belt, and double checked the timing, she started up fine and ran well Still going well now!

Is there such a thing on the deisel 205's called a "cold start valve?".

I ask as lumpy/naff idle when cold or indeed stalling on the 205GTi's is usually down to this. When i start mine up in a morning it's quite lumpy, even with a recent fueling tweak and new starter motor. Idles around 700rpm instead of 950ish. If I rev it to 2000 or so it misfires and then starts to idles properly.

Dunno if I have the same issue as yourself, but if the deisel does have one, I'd check it.

Tony - I'll dig out the manual & see where that sensor is - thanks.

Satancom - I don't have any Diesel timing gear so not sure now to check the timing? I was careful to lock off the pulleys etc when changing the belt so hopefully I got it back ok?

C-O-B - There is a thermoswitch/cable that opens when the water gets hot & connects in underneath the throttle cable on the fuel pump - that seems to open ok as it moves to its different positions depending on if the engine's cold or hot.

I have a nasty feeling this is going to cost me o get a specialist with the right kit to check it over - hope not as that's the sort of costs I try to avoid.

Will

have you checked the fuel pump m8??? or heater plugs?

seals on the filter housing maybe

I "think" the pump's ok - the car idles ok once warm (but I can't afford to sit for 10-15 minutes warming it up each time!); the glowplugs seemed ok when removed & wiped over - no cracking or burning that I could see.

I'll have a look at the filter housing to see if there's an air leak, but I didn't change the filter this time so hopefully the seal's still ok

Thanks all so far,
Steve

Steve, i have the same engine in my old rover estate, i think you'll find that the cold start mechanism is basically like a cable that gets pulled, which in turn activates a switch, the contacts on the switch get dirty, and then the cold start solenoid doesn't operate, therefore, it's hard to start when cold, but fine once warmed up....... the switch is on the pulley end of the pump, origianlly they were protected by a little rubber thningy.... but they break with age......

Hope this helps....

do you know if the Gti models had these too Ron?

hi
gti and diesels are two totally seperate beasts so the answers to diesel questions are not applicable.
first off recheck the timing(assuming i have read this correctly that you have changed the belt)you have 3 timing pins,one for the cam wheel,two for the fuel pump and one for the flywheel hole located behind the starter motor.
next you need to check the glow plugs are working correctly.when removed from the engine earth the body of the glow plug and put a feed wire to the small thread on the end of the glow plug,should take 15 seconds to glow bright red,if nothing happens it is buggered.replace them as a set because sods law states another will fail soon.
next,possibly the fuel filter is leaking air,you wont be able to see this so all you can do is replace the pipe between the filter and pump with a clear piece of pipe so you can see if there are any bubbles of air in the fuel system.
hope this is of help,feel free to email me on the diesel question only as i dont come on here very often neal
