Freelander 2, 2.2 td4 engine not starting

[sepistar]

Guys,
have an freelander 2.2 engine year 2008,which has stalled while driving and since never started again.
As recorded error pcm has P0698-16 Sensor reference voltage C - Circuit low
Have change crank and cam sensors but problem remain,it crank and never start.
On start pilot it starts but stops when no more spraying.
Btw try other pcm too,nothing changed.
In live data when it crank has 280 bar pressure and 2xx rpm,but simply it not fired.
Maybe someone has same situation?

Check timing

[autoden]

Reference voltage? Did you check it? The ref 5v must be on most sensor,s. Test at ecu first. One could be pulling the v down. Disconnect all, then replace one at a time, checking all the time to check.

[Black dog]

Disconnect dpf temp sensors.

ON TOPIC:-

unbolt lumpy stick sensor, leave in free air, crank few seconds, should instantly log lumpy stick sensor fault.

not sure on that EXCACT car, unplug egr valve if electric

[sepistar]

Disconnected all sensors including dpf and egr,reconnected one by one,
check dtc after each sensor disconnect/reconnect nothing bring it back to life.
Ground to ecu are ok.
Somebody has ecu full pinout?
edc16cp39

ON TOPIC:-

3 pin plug on fuel filter?

OFF TOPIC:-

had ford focus and where injectors were twisted they rubbed

That is a power suplly for some sensors , ignition on and measure 5 volt on camshaft sensor , dpf sensor .check in live data voltages .also could be power supply for injectors , edc16 has live data with that voltage around 80 volts . Did you check all fuses and edc powers supply ?

Check sensor supply should be 5Volts.....Had one a few months back ended up renewing the ECM as the supply to sensor from ECM was missing ...cant remember exact code but check supply

[sepistar]

ecu already change,problem remains.
some of the sensors have 5v.

[ecufix]

Does it start if you spray some quick start into inlet?

Member stated yes in first post "start pilot, stop spraying"

so, points to the loom has chaffed.

OFF TOPIC:-

ford transit 2002 ish, get fault "pump watch dawg"
basically wiring loom next to pump covered in oil and insulation fails

did you get to the bottom of this problem as i have the very same issue

[Meat-Head]

On topic:-

a fuel injected engine MUST have speed and load.
so start with map/maf sensor.

live data says?

[smokinjoe]

map/maf,egr,injectors,frp all disconnected,no change,would someone be able to help with wiring diagram and tell me which sensors are connected to circuit c
