Cold Start Problem Tdci 2.0 136Cold start problem
Posted 05 February 2013 - 04:53 PM
I have a 2005 mk2 2.0tdci 136 focus. For the last couple of months i've been having problems getting it started from cold. It's had new glow plugs, new EGR valve, new battery, but not fixed.
From cold, it may or may not fire up first time but then after running for a few seconds at idle it dies. I can get around this by reving the engine for a few minutes (not ideal when it's cold!). Sometimes though the revs will drop whilst I still have my foot on the pedal, then pick up again. After revving for a little while it's usually ok and I can set off (once it did die again when i dipped the clutch to change gear just aftyer i'd set off-not ideal in the mioddle of an industrial estate!). After a few minutes it works fine and there is nothing wrong with the performance. The problem doesn't really happen when the engine is warm either. It's been to my local garage (v good, but not diesel specialists), as well as a diesel specialist place-neither can identify the problem, which makes me thionk it's electrical.
I have had a dig around on the forums and it seems like there are loads of potential reasons e.g. cam sensor etc...I don't really want to pay ford to look at it all day then say its a £25 sensor!
Anyone had the same syptoms??

And Ippy, have you replaced the glow plugs ? Common on the focus, especially when its cold as it is now.

An old seal will be less pliant and tend to not re-seat properly resulting in air being sucked into the system and causing fuelling problems.

Can't help you with this mate, but I hope someone else can, as I think I have the exact same problems on my 55 plate 2.0 TDCi 136 as well!
Car is lumpy on cold start and needs a bit of revving to make sure it starts, after a minute of making sure I keep the revs just above idle I can take my foot off the pedal and it'll idle lumpy for a while. But when I take off there are absolutley no issues whatsoever with performance, no warning lights and no error codes. Been like it since I got it Nov 2011, and 40k miles later it's the exact same but has never let me down or led to any more serious issues.
When I first test drove the car it was warm so I didn't notice any start-up issues, same when I went to collect it a couple of days later. Then it sat on my drive for a few days til I sold my Mondeo and got insurance swapped over etc. So was a nervy time when I did start using it and noticed the cold start problem.
I took the car to my mechanic for a peace of mind service, genuine Ford filters all round and new glow plugs, and blanked off EGR as well, but made no difference. He was stumped then and still is. It's goin for it's 5th service in my ownership this weekend (Ford filters every time), and it's still the exact same. I've always feared injectors but I don't have any error codes and would have expected it to have given me more serious grief by this stage if it was. Mechanic had offered to flush the fuel system in the past, so might get that done this time round and see if it makes any difference.
What mileage have you on your car and what sort of MPG do you get, if you don't mind me asking?

Those symptoms sound very similar to what i'm getting Gforce...not too encouraging that it's not been solved though! I do get error codes thrown out occasionally but they often get wiped and dissapear-I don't know what they are...the gu sat my local garage did mention it, but I can't remember now what it was, should have paid more attention .
It's got about 137K on the clock, MPG is pretty good, usually 55+, but then again most of it is longer drives rather than around town...

I'll have a go at the fuel filter this weekend when there is a bit of spare light!

P1211 is injector control pressure sensor.
P0251 is injection pump fuel metering control.
P0191 is fuel rail pressure sensor circuit range/performance.
Hope this helps.
