I have an 04 plate 1.8 Focus Ghia TDCI that is very difficult to start in the cold weather. Starts on 2/3 cyl's only and gradually picks up. When warm seems to run ok but is hunting in every gear. Sometimes it will not start at all and I have been recovered twice. New Battery and Starter Motor already fitted and not losing charge. ????? Please!. (Tim from Maidenhead). Local garage removed fuel pump for testing. No fault found and problem the same when re-fitted.
Hello. My name is XXXXX XXXXX I will be assisting you today.
Once the engine has started, does it then start every other time until it is left to cool down again?
No!. Very nervous of it now. Problem seems electrical, starter faded at one time but recovered so battery and s/motor all good.
So it has bad starting all the time, not just in cold weather?
Yes! - You should know that when starting from cold there is a lot of blue smoke
Is there a lot of smoke
at other times
Yes - but this lessens to nothing as the car warms.
I would say the first thing that needs checked are the glowplugs.
Then you should have the amount of 'leak back' from the injectors checked.
All four should be very similar.
This was done but the glowplug warning light sensor is never illuminated for more than a second or two max.
You didn't say they had been checked.
Were they replaced or tested?
Sorry - never before used this facility.
Were they removed for testing or tested in situ.
Tested in situ.
What was the current consumption figure?
Before the problem 42/44 MPG. - now 30/32 MPG
Current consumption of the glowplugs.
How many amps were they consuming?
You test glowplugs by measuring how many amps they need.
I have no idea but I guess my mechanic might know.
I would suggest you get the glowplugs retested and the injectors leakback tested.
Thank you Mark. I will do that but what should the consumption be?.
About 12 amps per glowplug
Which reduces as they heat up.
