Starting problems from cold.

<< < (5/6) > >>

Mr Alford:
think its time for a full overhaul, fuel filter, fuel filter tank just off the fuel tank could be clogged up as water does settle in there, that could be ur power loss early in the morning, might be worth testing your fuel pump too

was it fine before ?
if it was heater plugs it would try to only fire on like 2 or 3 cylinders and you can hear it as its trying to fire,
200 and 300tdi engines dont really need glow plugs to start, my challenge truck ( 200tdi) doesnt have them connected and i can go to it after a month of it not starting and it'll fire up at the flick of the key
dont be confused ( not insulting here but some people think it ) dont think the glow plugs run constant, there only there for initial start up to assist the engine

Don't worry, I know they switch off after starting (or when the dash light goes out)  :lol:

I think I'm probably being a hypochondriac again. It fired up perfectly a couple of days ago after a brief churn and settled down to the usual rough cold TDI idle within 30 seconds or so, which is pretty much what it always does in cold weather. The cam belt just happened to be changed during the first cold snap of this winter, so it's most likely a co-incidence.

I may order new heater plugs anyway as they're £2.50 each or something equally daft.  :D

I know the answer. It's dead easy.

Its a 300tdi!!  :twisted: I am on to my second engine now and both dont like starting in the cold.  :doh: :-k

I've still yet to get time to sort this out but...

Yesterday I drove it VERY hard.  Always using the kickdown. Foot flat pulling away from junctions.

My fuel economy was rubbish but it's started much better today.

It does make me think that there is (or was) a blockage somewhere.

Tomorrow's my day for the stripdown but if it starts easily when I leave work tonight I might not bother doing anything.

I am always driving mine hard to just make it go at a normal speed!!! :lol:
