Starting problems from cold.

(1/6) > >>

jkseries:
OK so the ice on the windscreen brought with it starting problems this morning.

I've always had trouble starting the disco but today it was even worse.

I've always had to leave it idling on the drive to warm up otherwise I suffer from a loss of power within the 1st 5 mins of driving.

I've replaced the glow plugs and seem to have power going to them.

My next thought was an air leak somewhere so I've checked all the hoses from the tank forwards and there doesn't seem to be any leaks of any kind.

I'm thinking lift pump but none of the symptoms I've got seem to tie up perfectly with anything else anyone has described.

I'm running on a 50/50 mix of diesel and WVO at the moment but still get the same symptoms when on straight diesel.

Can anyone point me in the right direction of where to look next?  Is it worth putting a new lift pump on? Because fueling seems to be fine when I get going I don't think it would be the fuel pump (but i may well be wrong).

Help please.  As the mornings are getting colder and I still need to get to work.

Any advice would be great.

EDIT: Sorry forgot to say it's a 300tdi auto. Thanks

I'd try the fuel filter, then the lift pump. When my lift pump went the only time it was really noticeable was starting from cold and at tickover, more revs and it was just down on power. I didn't notice the loss of power until I put the new pump on, at which point it was noticeably quicker!

BigA:
I would try the fuel filter too, when i ran on mixture of oil had many problems with the filter. Its a cheap and easy one to try first too.

Saying that, i have not run on oil for a year now, changed fuel filter at least twice since then, and the cold weather is already causing havoc starting in the morning  [-o<

jkseries:
Forgot to say it's had a new fuel filter.

I ran though about 80l of 'fuel' and then changed it.

When I changed it the disco had been sat for about 12hrs and there was only a dribble of fuel in the bottom of the old filter.

Could this be pointing more at the lift pump?

Disco Matt:
You could check the fuel sedimenter too - on the inside of the right hand chassis rail near the fuel tank IIRC. But this is sounding like air is getting in somewhere when the engine is off, most likely the lift pump.
