Post subject:  05 CRD stall immediately after starting

My 05 CRD has an issue where it SOMETIMES runs rough and stalls immediately after start up. It sounds terrible when it does this, runs extremely rough shaking the whole vehicle and often stalls. Sometimes it doesn't quite stall and after 4-6 seconds it will smooth out and idle perfectly. This rough running occurs about 2-3 seconds after I start cranking. When it doesn't do this it starts beautifully. I have worked out that if I continue to crank through this rough running it will run this way for about 4-6 seconds and then come good.

It also occurs straight so soon in the startup that I don't even have a chance to change gears ( its an auto)

Couple of points
This ONLY ever occurs immediately after starting.
It ONLY occurs when the vehicle is cooling down , never when the vehicle is cold and never when I start it within a couple of mins after turning it off.
I have replaced the fuel filter and I'm now checking before I start and I have never found the fuel primer to be soft.
I replaced the Cam and Crank sensors, the relationship of this issue to the engine cooling down pointed me to that as a possible reason.
I have replaced the MAP sensor also after I installed the weeks stage 1 kit
There are no issues when driving, it runs great, I'm getting good fuel economy and it doesn't appear to be lacking power.

the only error code I'm getting ( besides EGR related ones ) is p1140

Its annoying because my mechanic has never seen it do it, I guess he needs to test it more but id like to fix this myself if possible as I cant get him to look at for a few weeks. Id like to avoid taking it to the official dealer also due to their insane prices.

One thing is that the fuel heater has at some time had the heater wire unplugged and a non standard plug fitted which means I can no longer plug the heater in.This makes me think one of the previous owners noted the fuel heater issue that is well documented, however there is no appearance of scorching or fuel leaking and the issue only occurs when starting.

My alternator pulley is exhibiting some red dust, I have a spare and will try replacing it soon, it seems unlikely this is related though?

My first thought: P1140 is the FCV valve. Possibly shut closed and thus limiting air flow to intake (it pulls exhaust into intake when closed). But I see that you installed the Weeks kit, so that blows that theory......


Thought 2: fuel injector problem. Fuel dribbles out after shut down and collects in the dish of the piston. Or maybe it doesn't open at all for a few seconds. Either way causes an imbalance and thus the shaking.

Another thought..

The symptoms you describe indicate that all the glow plugs are good, as they work fine when the engine is dead cold, and it starts fine when fully warm, which indicates it's not a fuel problem.

I'm guessing the coolant temperature sensor may be giving faulty information at some point of it's spectrum, and is leading the ECM to believe that the engine is warmer than it really is. The ECM then believing the wrong information, fails to activate the glow plugs when it actually should.

The alternator pulley could have an effect of making it worse, but doubtful that it would be the cause.
Really recommend putting the new unit on before the existing one fails entirely.

Does it stall immediately when you put the trans into R or D ?
If so, check your trans fluid level at idle while cold. It should be above the full hot mark.

If it stalls before you put it in gear, then it’s a fuel system problem.

If you can, post a picture of your fuel filter head so we can see what you have.

i say ,, for north american CRD model 1st think to do is get in tank lift pump , and then list gets longer and longer till you get to second page of the modification list , it will take few years to complete .

GordnadoCRD, it's that the temperature sensor located near / in the thermostat? I don't have a pc but I remember removing one when I replaced the thermostat It occurs to me that could be an explanation as it certainly appears to be related to temperature. I don't beleive it is anyway relayed to the transmission it occurs before I have a chance to change gear.

Yes, it threads into the rear of the thermostat housing.

It's the little blue thingy behind the T-stat housing that you can barely see for all the other hoses.

I'm thinking given how cheap that part is and easy to replace its worth a shot.

Post subject:  Re: 05 CRD stall immediately after starting

Ok I have replaced the temperature sensor as well as the serpentine tensioner and alternator pulley.

Issue is still occurring.

One thing is if I hit the accelerator during this rough running time nothing changes, its almost like the engine is in some sort of warmup mode where it doesn't take input from the throttle.

I don't think its the fuel filter, id have other issues if that's was fault id imagine.

Mystery continues

If it was a fuel filter issue, it would affect it a whole lot more while running than at startup!
From what you describe, it sounds like it may not be building proper fuel rail pressure at times to allow the injectors to fire while cranking? :roll:

There are several things that can play into this!
Fuel Pressure Solenoid end of fuel rail
Fuel Rail Pressure Sensor side of fuel rail

The below two items are the same thing, but you may see them called two different things.
Located on back of CP3 injection pump:
Fuel Pressure Regulator
Fuel Quality Solenoid

You really need to know what your fuel rail pressure is doing when this phenomenon happens in order to do a proper diagnosis! :roll:

GordonCRD on this forum is really the subject matter expert in this area! :wink:

Post subject:  Re: 05 CRD stall immediately after starting

if you are 100 % sure low pressure side is ok and no air in fuel , you my have one of the injectors acting up funny , it will get worse , like start sticking and making rattle nose

is there any way i can check the fuel pressure? or check the functionality of the solenoid or pressure sensor? ILl check my OBD reader but i dont think it has fuel pressure as a field i can view

update

ok I connected torque pro to my OBD reader and when it does this rough running the pressure fluctuates fairly wildly. But I feel this could be a symptom rather that a cause. what sort of values should I bee seeing?

Id love it to bee the fuel filter head because I can replace that fairly easily.
I double checked what codes I'm getting

P0102
p0403
p1140
which are all related to the EGR system?

B2TAE - cant find any info on this one

B2tae would be some sort of Body (BCM) code, but I can't find any information either. Low voltage, dead batteries, or a jumpstart can sometimes make the modules vomit up nonsense codes.

Regarding your fuel heater I very much doubt it has anything to do with the symptoms you describe, but as it is a safety issue, I suggest moving it to the top of your list.

P0102 is a Mass Air Flow sensor circuit fault. It incorporates the Intake Air Temperature function, which may circle you back to the "Never when hot - Never when cold, - only when somewhere in between" issue. Do you know when this code appeared? Is it persistent? (comes back immediately after being cleared) or could it be an old code? I've had to do little tricks with the MAP sensor and Fuel Pressure Sensor right next to it. I don't know why, but they seem to be prone to have intermittent continuity issues. I don't know if it was wires or connector pins, but when I put new connector ends on, it hasn't happened since. My guess is from engine vibration working on them constantly.

P0403 Your EGR solenoid isn't making the ECM happy. This is normal after doing Weeks EGR "fix" Tunes can solve this issue, or, you can take the solenoid off the EGR valve body, plug it back into it's connector, and zip-tie it out of the way. I wrapped mine in rags so it wouldn't rattle about or wear on things.

P1140 Vacuum reservoir solenoid (over by the power steering fluid reservoir) shows an electrical fault of some sort. Could be the solenoid it's self, or just the wiring or connectors. It may also be an old code.

Have you cleared all of the codes, then see which ones come back? How they come back? Under what conditions?
I see you've tried a lot of things, so I'm not assuming you overlooked anything. I just want to make sure so we don't overlook things.
You state that your fuel primer button is always fully firm. I didn't see any mention of a fuel lift pump, but that statement leads me to believe you have some sort of lift pump installed? Please correct me if that is wrong. If you do, that would rule out a whole subsection of possible problems.

Most scanners - even my crazy little $25 POS I got from an Amazon Day Sale last month, - shows some elements of Live Data. If you have someone monitor that while you start up a few times, and drive around, it's slow, but you can log some data points of Fuel Rail Pressure to see what it's doing.

Diesels running rough when starting cold is normal, but when it's partly warmed up, all it should do, if anything, is just take an extra revolution or 2 to fire up.

The injector leakage possibility mentioned by others is a very reasonable theory, the problem is, if you don't live conveniently near a competent diesel service business, you may lose some days loss of use while things go back and forth. But that's the only way you will find out which injector is causing the problem, - if any. Most good shops have reasonable testing rates. The big bucks come out when it comes to replacing with properly tuned injectors. Captain Dean found that the ones from Britain can come already tuned to the same injector code as original, (you don't have to re-program the ECM) and the prices are reasonable?

thanks for all the info, im going back over everything to see what i can work out.

I cleared the codes, 0403 and 1140 came back but no 0102. But thats only after idling in the driveway for 5 mins. Ive noticed only today that its seems to be struggling even more , it feels like i have to crank for longer when it does the rough running to get through that stage and it now the rpm is going up and down when its idling. the rpm is jumping up and down by about 50-80 rpm like im very lightly touching the accelerator every 2 seconds, its rhythmic.

Ill take it for a longer drive tomorrow and see if the 0102 code returns. Where is the Mass Air Flow located? or is that more than 1 sensor?

With regards to the fuel filter head the primer pump is pretty firm, I can push it maybe 1, 1/12 times before it becomes extremely stiff. I checked today by loosening the bleed valve and a little bit of air came out. should there be absolutely no air at all? ( no lift pump unless previous owner did it which I highly doubt) Even if I do push the primer down once or twice until it gets extremely stiff the issue will still occur. Perhaps I should replace it anyway, I'm just getting a bit sick of throwing money and hoping ( learning lots mind you )

Check this thread out. As you go through it, most all that stuff is explained, and could help you decide what direction to go.

This sends up all kinds of red flags and concerns me!
It should NOT be doing this!
As I mentioned in earlier post, one of the fuel pressure control devices, either the one on the fuel rail or the one on the CP3 pump could be the culprit! They are mechanical in nature and one of them could be going bad.
And as others have already stated, it could also be an injector problem, leaking, sticking, or generally going bad!

Define wildly.

+/- 10 psi isn't bad.
+/- 100 psi could be bad.
Normally, at idle fuel rail pressure is 5000-6000 psi.

Here is an easy test:
With the engine running at idle and monitoring rail pressure with TorquePro, wiggle the connector at the fuel rail pressure sensor.
If rail pressure goes crazy when you do that, there is a loose connection at the connector.

Yes it is. You are right.
That is what I meant to say, but my fingers got confused or something.
Thanks for catching my error.

Post subject:  Re: 05 CRD stall immediately after starting

I have posted a vide on YouTube ( https://youtu.be/sCI8aSls-mE ) to show what I'm experiencing. Interesting thing I have noticed is when it runs rough and I have to keep cranking at pretty much 5.2 seconds it comes good. I tested that many times and used GoPro studio to measure the time precisely as I could and it always comes good at pretty much 5.2 seconds every time.

It really sounds like a fuel starvation issue when you listed, but I cant explain why it only ever happens when I start. And never when its cold

I'm thinking about replacing the fuel filter head anyway for safety. its a good long investment ( the heater us currently unplugged BTW )
