hi all 

my Focus 2004. 1.8tdci 74kw has a crank no start. It has no fault codes, it reads RPM, althiugh the rpm meter doesnt move, changed the crankshaft sensor. It reads enough fuel pressure , over 300bar. It suddenly stopped then the garage changed one injector and it worked for a bit then failed then they changed all injectors and never started again. Im trying to see if there is an impuls at the injectors but its hard to see, a led light we dont get to flicker but a volt meter swipes a bit wildly. It brabbels when we put in brakeckeaner. All fuses seem ok. Where to look for now?

many thnx

Welcome!
I'll ask what is a usual question: are you reading codes with Forscan? (as generic OBD readers don't find Ford specific codes)
How are you measuring the fuel pressure (Forscan usually has demanded and actual)?
I don't like the sound of changing crank sensor (why?) and garage changing one injector (why?) and then the other 3 (Why, why, why?) - is all of this just trial and error?
If it RUNS on brake cleaner then my opinion is that there's enough compression and valve timing may be OK.
However if PCM isn't happy with something, then it wont operate the injectors (although you may have a signal)

Rev counter not moving may imply that PCM doesn't know what is going on - is this model subject to the instrument panel fault (I don't know)?

Consider the above and we'll wait for other comments...

Hi thanks for your reply. We are using a general but medium expensive reading tool, not the brand you mention. Unfortunately it doesnt show if crank and cam sensor sinchronise/are happy together. The crank sensor i ve replaced it because between impulse and earth/mass pole on the sensor ( connector of) i measured a resistance of 14,8ohm and i ve been told that shouldnt be there. The whole injector changing; the why i dont know its done by a previous garage and i agree so far doesnt make sense. They end up saying its the pump and it wil cost 3000 euro. The fuel pressure we measure on the scan tool. Hope this helps. Yes i read that the RPM meter is not directly connected to the crank sensor, and only if ECU is happy will show RPM on the dash (?)

Injectors going on the tdci is very common.. if l remember right they need coding so it knows there the correct type n so on. The speedometer do suffer from dry soldering but from what l remember it just affects the speedo it's self.

Forscan software is free (unless you need to program when a cheap licence is available but you do need an approved lead)
It is Ford dedicated with multiple specific functions which is why it's recommended on here.
The history of changing injectors (which I believe can be coded by Forscan but I'm unsure if crank/cam synchronisation can be see but I would expect so) tells me that there is some testing (leak off?) and diagnosis missing?
When an HP  pump is suggested and you have high fuel pressure (would be nice to compare actual and demanded values (Forscan again, if possible or your scan tool) I shudder as there has to be some serious testing first (glitter in fuel filter etc?)
And then there's possible wiring faults/ corrosion etc on a 2004 model?

As to your mention of forecast coding the injectors it should be able to do that as l knew someone who did there mk3 mondeos with it. I've never had the tdci engine so can only go by what I remember from the past but l don't see why it wouldn't work with it.

UPDATE_UPDATE_ we're lost !

We've connected a Forscan. Initialy It mentioned "Pats Service module" "Denied" but miracles it cleared that. We see a Sync, for CPS state,  we see RPM, we see desired and given pressure, no faultcodes apart from P1000, but I understood I can ignore. So now we get pretty lost. I red that if there was a perceived accident it may be refusing the injectors to fire up but couldn't find that yet in Forescan.  We are assuming the injectors get no power, but tomorrow will back probe them wit Oscilloscope to definitely confirm that, any thoughts. Could key still be at fault - the car was standing still with dead battery- although no fault codes? Attached you see the live data results. Whats the next step? We do see " Vehicle security acces" in "process" does that mean he tries to recognize the keys but fails?

If 131rpm is the best it's managing then it won't start.  Needs to be minimum of 200rpm on the starter, ideally I'd be looking at 250+.

As already said by @TomsFocus the cranking RPM is too slow. The injectors will not be fired until cranking speed is past the minimum.

Is the battery flat or low on charge ?

Are the battery and starter motor cables in good condition ?

Thanks it starts with 250 cranckings then it drops. 

If it can't maintain the cranking speed while trying to start, either the battery is dying and needs replaced, or the starter motor is failing.

We replaced the battery it cracks like new. But it wont help. I am focusing now on the "sync - no sync" that I read if thats ok and I 'll make a new topic.

 

The fuel rail pressure is way too low but that's at 131 PM.

What is it at normal cranking speed which you say you now have?
