Hi.

I wonder if anyone can help. I have a 97 300TDi Discovery that has two problems at the moment. To start with it has had a new timing belt, water pump, fuel filter, battery & glow plugs before I got the vehicle about 2 weeks back and I have verified all the work was carried out.

Anyway maybe not in relation to all the above the problems I have is it take (hot or cold) about 10 turns on the starter to fire. I never pump the pedal or heat the plugs more than once as it seems to make it take even longer to start!

The other problem is if I have the motor idling and I give a sharp blast of the revs and back fully off the throttle straight away it drops to about 500rpm farts and squirts for about 10 seconds then cuts out. I can rev it up and down or hold it wherever, and as long as I back off the throttle slowly back to idle it never misses.

Any help would be appreciated. Also forgot to mention I have fitted a new glow plug relay and tried to make sure there is no air in the fuel system.

Sorry for long winded post but trying to cover everything.

Cheers.

sounds fuel related, check or remove the sediment bowl that is located on the right side of the car above the rear axle and remove the gunge that is inside it (had similair symptoms on my own a few years back)
 
Cheers Stig.

Is there anyway to actually diagnose the lift pump? Also could it be anything to do with the fuel solenoid? I have read a fair few posts and this keeps coming up...

Thanks again
 
fuel solenoid would stop it from starting all the time and it wouldn't allow the revs to die it would just cut the fuel off straight away. Remove the pipe from the filter housing that comes from the lift pump and have it feeding into a container to stop fuel going everywhere and operate the lift pump lever there should be a lot of fuel coming out on each stroke
 
Stuck in the new genuine landrover lift pump last night. Cutting out as it drops to idle has got a lot better as well as general cold running.

Still an absolute nightmare to start, hot or cold but worse when cold.

I'd appreciate any more input and thanks for what I have already. I was thinking about doing a direct feed from a jerry can of diesel to rule out everything from the tank upto the filter with regards to air etc.

Cheers
