Hey guys,

Really after some help on this one.

I have a 2007 Ford Ranger Thunder 2.5l TDCI which has developed the issue of not wanting to start once up to temp.

It will turn over for a couple of minutes before finally firing up!

When left to cool down it starts up absolutley fine, as it does first thing in the morning and after work just not when warm.

I have had the truck looked at by a local garage who didn't have much joy, and even had it on Fords diagnostic machine which showed no errors what so ever?!

Now my local garage have advised that it may be an issue with the ecu and have recommended sending the ecu off to be checked, but just wanted to see if anyone one here has had a simular issue or could advise of anything they think it may be.

Any help would be much appreciated.

Cheers,

Kristian

You got a Coolant Temperature Sensor on that?

Could be any number of things, and just because the diag equiptment dosnt show a fault doesnt mean their isnt one, a sensor which is out of range will not show as a fault, but can be detected using live data readings.


Everybody automatically assumes the faults are electrical these days and forget mechanical basisc's
I seem to recall the 2.5 tdci has stretching timing chain issues and low fuel pressure issues

Cheers for the Replies.

I'm not sure if the truck has a coolant sensor, could this create a problem like I have described?

Yeah I initially thought it was like a lower fuel pressure issue, but when cranking the engine over diesel is definitely being pumped through.

I haven't checked but I thought the 2.5tdci used a cam belt?

It's just strange that it only happens when the engines hot.
I did have an issue with an air lock in the coolant system a few months back, whether that could have played a part?

Cheers,

Kristian

Just had a quick Google, as wasnt sure myself, some say its chain and others belt!!!!
Yes it can be a temp sensor fault, I.E its gone out of range, only way to know for sure is to either change the sensor or do a live data reading.
It will definately have a temp sensor even if theres no temp gauge. there has to a temp sender to tell the ecu how hot the engine is.
How do you know fuel is being pumped through? This is a common rail diesel, if youve cracked off a pipe on the high pressure side it should either slice through sheet steel or take your hand off, cranking pressure needs to be about 150 bar or 2,200 psi before the engine will fire, a good "squirt" isnt enough anymore.

Could it be as the engine heats up something is expanding and killing/choking something off?

I'm with Ivor, sounds like one of the temp sensors, there my be more than one, possible to have an ambient air temp, fuel themp, coolent temps sensors. I have also seen cam sensors and crank position sensors throw in similar faults.

Don't 'crack' off a fuel line on a comman rail engine its not only bloody dangerous but you will introduce air to the system so you will have two faults to find at the same time.

TBH I'd take to a decent main stealer or automotive fault finding specilist an to find the fault. Who ever stops at looking at fault codes and says there is no fault is a muppet and dosnt deserve to work in a workshop, most problems never throw in a fault code as Ivor says.

PS ford tdci engines should all be chain driven cams from 2006

Thanks for all your replies!!

Yeah i originally thought fuel pressure sensor or crank position sensor but was thrown off when it went through diagnostic without any issues being flagged.

I will be taking it back to my local garage next week, so hopefully this time they will be able to find and rectify the issue.

Cheers,

Kristian,

Not the same car but similar fault.My TD5 110 would sometimes fail to start when it was warm. Engine would spin over but wouldnt start, other times it would click click click.
When it was cold i,e overnight or left while in work all day, it would start first turn of the key.

Fault turned out to be the starter motor wasnt spinning the engine quick enough for the crank sensor to get the correct reading. This was caused by the windings in the starter motor that control the solenoid plunger not being strong enough to hold the plunger in place to make a good contact during cranking.

Swapped the starter motor and all is good.

Cheers excossack.

I hadnt even thought of the starter motor.

I have noticed that when the trucki s hot and refusing to start the starter motor cranks over at a certain rpm but then noticably speeds up just before the truck fires up.

Some times the starter motors rpm speeds up as if the trucks about to start and then slows back down to its regular non-starting speed.

The issue has become progesively worse too, were it used to fire up after a few seconds to now taking literally a few minutes.

Does this sound simular to your 110?

Cheers,

Kristian

My 110 sounded like it was spinning at normal speed and sometimes I would crank for what seemed like a long time and sometimes I think it was trying to start and wouldn't.

i had a similar issue on a 106, was somewhat annoying at petrol stations, pull in, fill up then have to get pushed out the way and wait for it to cool down.

Changed 3 temp sensors and the throttle body with no luck, turned out to be a corroded plug between the sensors and the throttle body Confused

Haa yeah filling up can be interesting!

I'm leaving it with my local garage next week so hopefully they will be able to shed some light on the issue with incurring to much cost.

Just seems to be a case of replacing things until its resolved!

Cheers,

Kristian

I would expect a garage to be more switched on then just swapping stuff and hoping, especially if they're charging you parts and labour, even I can do that!

My local garage has a touch screen thing they plug in, they can view all the error codes and clear them, but also see what each sensor is doing, what the car is trying to do etc and combined with manual testing in the hands of a skilled operator they can pin point faults really well.

Just got my ranger back after being in the garage last week.

The mechanic has replaced my engine coolant temp sensor as apparently this can throw the start up out if faulty.

Now it currently is starting fine but can still take a few cranks before firing up.
Hopefully this has sorted it, but I'm still not convinced.

Cynic-al I've had the ranger back to ford on their diagnostic machine and no fault codes are being logged at all, even when the trucks not starting.
This is not to say there wasn't a dodgy sensor, just the fault reader didn't pick anything up.

The mechanic I use is a real decent guy, but was literally stumped on this one! Ha.

Hopefully it's now sorted, but if not I'll let you guys know Smile

Cheers,

Kristian

Well, I'm a bit anti dealer, fallen out with too many of them, maybe it's me and I just ask too much!

Glad you've got it sorted anyway Very Happy

Sorry to drag up an old post but I am having the exact same issues with my 60 plate ranger, did it continue to start after having the coolant temp sensor or was it something else ?

Read the trade magazines, it happens all the time and guess who pays for the wrongly diagnosed new parts....

I'll give you a clue - it ain't the garage
