Mondeo 2011 Turbo Diesel lack of power

(Not something you should do often!)

At this point verify the timing as well, I think the diesel is as for the PSA 2 litre petrol and has a flywheel pinning hole to its rear. Be careful not to wind the motor backwards if you miss the timing point - go around twice more.

No, turns over but wont start.

Regarding the timing, it was fine before i started working on the intake manifold. i can't see how the intake manifold and injector removable can offset the timing. If it is a timing chain issue, then it's an amazing coincidence a bad chain causing to mess up the timing on the next start after. But hey..... those odds of such a coincidence to happen to me is likely. I am that cursed.

By the way, if timing was off, surely i would get a number of codes. But i will check it out anyway and thanks for your tips.

Slight mistiming generally gives a cam sensor fault, leading the novice to replace that sensor.

Testing for firing with another fuel (or even a splash of diesel into the intake) is a good way to see if the mechanical aspects of a motor are sound.

I do appreciate your time helping me out Citroen thank you.

Still not getting the full 12v power into the sensor which is strange but getting the 5v from the signal wire which is supposed to.

To verify timing, i will check and lineup flywheel with the pinning hole. If i do that, would i also need to remove the timing belt cover and check that the camshaft and crank all lineup aswell? So it's virtually doing a timing belt change without placing a new belt?

It’s not a two minute exercise, no. Less effort than changing the belt, though.

I've only had the car 6 weeks. It came with a full service history (but doesn't specify what was done as part of these services)

What i have done so far so sought out the lack of power and now non start:
A) Test and clean the injectors and add new seals to injectors
B) change transmission fluid and filter
C) New intake manifold gaskets
D) Decarbed the engine intake ports and manifold using a Diesel engine intake Decarb fluid (check photos below and see how bad they were). The injectors were out at the time, i would have had the decarb fluid going in the injector ports, not sure if that was a good idea and caused some contamination or damage.
E) Change engine oil and filter.

PS: After posting this i ran the scan again and the P0087 Code: Fuel Rail/System Pressure Too Low disappeared on it's own overnight.
But still won't start.and no codes or dashboard warning lights.

Mine wouldn't start at all if the battery was less than good, it'd turn over and never fire, even with jumper leads on it. Or eventually on leads with about 2 minutes worth of cranking, and then it eventually blew a huge black cloud out the exhaust and ran like a bag of dicks than calmed down - it was a picky piece of shit with batteries.

It also used to kill them every 12 months until I MacGyvered in a massive DIN85L sized battery.

You got a battery charger? Put it on the car overnight and then try start in the morning and see how you go.

Also check condition of main earth cable, on the Focus its on the passenger side shock tower, unsure on Mondeo but could be similar as they share a platform.

I did put it to charge overnight. Though admittedly my battery doesn't hold charge but usually enough to get it started. So eventually i will replace it with a new one. I'm just concerned money being spent is ticking over with lightning speed. These Mondeo batteries are not cheap $250 - $350 then only to scrap the whole car for $350 if the car has major problem where it's not worth repairing.

I'm starting to believe i have a timing issue which i'm going to need a new belt. **** me how did i get myself in this mess.

Just learnt from Alan Howatt in one of his videos, that the high pressure fuel pump needs to ne timed also with the power train timing. If the timing is out with the fuel pump you don't get the injector spray in sinc. Maybe that was the original cause of loss in power.

When they did the timing belt on mine, the balancer pulley bolt come out a few threads and then snapped in the crankshaft with a nice clean shear

They needed to get some specialist in to get the snapped thread out of the crankshaft, which took him all day.

Be prepared for a fun* time

*will not be the usual definition of fun

If you got good quality jumper leads, get another car onto it, but go to the negative terminal on the Mondeo, not the Mondeo body earth as its not big enough to get enough current through to turn over diesel engine fast enough to get it to fire.

If its like the Focus its a pain in the *** because the negative terminal sits under the wiper cowl, might need to take off the wiper cowl to get enough clearance.

How good are European cars?

Yep so is the Mondeo negative terminal. They just wanted to be arseholes when they designed them i think.

Re timing, i'm just going to check if the timing is ok and adjust it if need then retention the same belt, thats if the belt is one piece. So i wont need to unbolt the balancer pully.
