mk7 transit not starting!

Postby eurokiwitransit » Thu May 10, 2018 7:49 pm

Hoping someone can help.

Recently bought a 2011 2.4tdci 4x4 transit. Bought it in Leeds and drove it that night for 14 odd hours to central europe. The next morning, it took approx 10 secs of cranking before the engine fired up.

Since then, it's progressively got worse but inconsistently. Sometimes it'd start first pop (cold and warm), sometimes it'd crank for a while, splutter and then start, and others it'd just crank and crank and crank and never fire up (as if it was out of fuel). Batteries are all ok. Bump starting it would fire it up.

It's at it's second mechanic now as the first one wasn't interested. He scanned it and said it had an EGR fault. Van has been remapped and EGR deleted.

Could it be a fuel issue? Sensor of some sort? What could cause this?

Sometimes when idling the van used to fluctuate revs slightly like it was hunting. This was quite minor but it always idled well despite this.

It's at it's second mechanic now who is very busy and not super interested in it. If I had a few ideas of what it could be I could suggest them to him to check.

Thanks in advance.

Forgot to mention the check engine light came on while I was driving it in the UK still a few hours after picking it up. After a week or two driving around Austria (when it decided to run) this turned into the powertrain warning light (yellow cog with ! in middle). Not sure if that makes any difference!

Ideally needs codes read with a ford ids system.

Also live data check when it does not start.

Otherwise it is guesswork.
Could be any of following :-
Crank sensor, cam sensor, worn timing, air leak in fuel system, bad fuel filter, bad fuel filter housing, wiring fault.

And don't bump start it ! this might even be the continuing cause of you problems.

Thanks mate. I'm going to the mechanics tomorrow so will see if I can get a read out any codes and add them here.

I doubt he has a Ford system though. Nearest Ford dealer is a few towns over from where I am and booked out until June!

A good commercial code reader should do as well as ids.

Important thing is if it does not start, what does live data show.

Thanks again. By live data do you mean the data being read as the van is attempting to start?

I could so easily be barking up completely the wrong tree here, I'm a gardener, not a mechanic, but is this a case that could be helped by the free Forescan software, a laptop, and the lead to connect laptop to vehicle?

Yep it would read codes and show live data like cam and crankshaft sensor sync, etc.

Yes

The live data can show you the cranking speed of the engine, whether the cams are synchronised, the fuel pressure and lots of other info.

No engine speed data when cranking suggests crank sensor is bad.
No cam sync can be cam sensor or timing problem.
No fuel pressure could be air leak, blocked filter, pump inlet valve.
Fuel pressure low could be air leak, blocked filter, pressure relief valve.
Or any of a lot of other problems.

You guys are a bunch of legends, thanks for all your help so far.

I've just come back from the mechanic. I'm in Austria so there's a bit of a language barrier but I speak pretty good German, here's what I understood.

They suspected it was a cam sensor. They replaced the cam sensor and the van started twice and then it wouldn't start again. It also worked with the old cam sensor in sometimes.

When it ran those two times with the new cam sensor in, there was no fault codes. After it stopped running again it was saying that the cam and crank were not sync'd. This is the only fault they say it is showing. I've also been told by another guy that when the sensor knows the cam/crank aren't sync'd that it cuts power to the injector pump so the van can't start. Does this make sense?

Given I have bump started the van 4 or 5 times due to the starting issue, could this have caused the cam chain to jump a tooth?

What I can't get my head around is that the first symptom was a slow start (cranking 10 secs or so) the second day I owned the van. After that it fired up fine. The only fault showing at this time (according to the first mechanic) was EGR valve issue. So the starting issue was developing before I had ever bump started the van.

Would this suggest there could be a starting issue on top of the cam chain alignment issue? Thinking out loud here! All your help is hugely appreciated!

Just an odd thought, when was the oil and filter changed ?
It might be a chain tensioner problem rather than wear. Tensioner is pressurised with engine oil and old oil or the wrong grade can give problems.

Try an oil and filter change if you don't know when it was last done.

Otherwise I'd suggest that the timing chain is worn or stretched, and there will be general mechanical wear throughout the engine.

My understanding is that when the chain jumps even a single tooth you get damage to the top end of the engine.

Or another reason for intermittent cam sensor fault would be wiring between sensor and PCM. Most likely where harness loops down from engine up & towards engine bay fuesbox.
If sometimes it's starting and others not it doesn't sound like timings out?

I agree with this I have this problem and it took me 3 months to sort it

before this problem i rebuilt the engine for other reasons it was running but was f*** :( anyway rebuilt the engine put it back in, the thing i would turn over but not start.

took timing cover of time and time again all timing bang on but still had p0335 :( :( live data on ids was saying no cam and crank sync

it turned out to be a corroded signal wire from the cam sensor within the wiring loom :( and only broke as i was messing about with the wiring loom :wink: once i pulled the the loom apart from fuse box to engine it was clear it had water ingress and rubbed threw wires causing the corrosion of the wires and their was the signal wire from cam sensor to ecu corroded and broke :shock:
