Hi

If you can only start with a tow start, then this could be one the following issue .

Slow turning starter motor .
Weak battery .
Low compression .
Glow plugs system not working .

First start with the starter motor does it turn the engine fast .

If it does then next check the glow plugs ,when you turn the ignition switch to the ON postion does the glow plugs get power ,check with a test light should turn on for 10 - 15 seconds depending on the temp of the engine .

Then check the engins compression if to low the engine has to turn fast ,like getting a tow start to get the engine running .

I want to know why the car won't idle.it won't idle below 950 rpm. The car start in very short space. what is the car looking for to idle. Change the battle too.
Expert:  indy-tech replied 3 years ago.
Hi.

Irlam do a compression test, as this will give you a bad idle or none under 1000rpm .

How many miles do you have on this engine .

Has any work been done on the engine before you had this issue .

Was the items checked and tested what i suggested above .

compression all 3 reading around 10.5 bar .


79k miles on the car.check injectors coils all at .5 , removed rocker cover to check rocker arms

Expert:  indy-tech replied 3 years ago.
Hi Irlam

10.5 bar is very low for a diesel engine, you should have a Min of 16bar. and normal is 23bar.
A normal petrol car will have 12bar .

Diesel engines need high compression to produces friction and heat to be able to run correctly .

Looks like you need a ring job on this engine Irlam.

tested compression again up little more. i can under stand low compression 1 are2 cylinders but all the same. this car was driving and would idle up to this. is the cam pick up point at the top at tdc . can the pin are key brack in the cam wheel. the belt would be timed ok to each wheel. is the car looking for anything when in idle. how far can the cam belt be out .when car is running it drives ok

Expert:  indy-tech replied 3 years ago.
Hi Irlam .

Yes all it takes if for the T belt to be off one tooth and you would have this problem .
check the timing belt is still on mark .
