Mk 7 minibus 2.2 tdci

I reckon the injectors are fine, and it's the piston that knackered

I guess we'll soon find out mate...!

Ok haven't had time to do pressure checks yet but engine cuts out when something clicks under drivers seat any suggestions ?

The battery disconnect relay switches off when the engine stops

[Gjinna]

Ok jus to update you guys after pressure testing I decided to pull the head off the engine and sadly number four barrel is all scored so guess I need a new bottom end. Could anyone tell me if a mondeo tdci will fit

[Gjinna]

thanks for all the replies guys in the end i stripped the engine to find no4 cylinder was scored badly causing loss of pressure £700 later for a recon block and £200 for injector reconditioning and the bus now drives like a new van

[Gjinna]

things are never easy for me :/
driving the bus last night all fine then sat on tickover for 5 mins and it just dies
tried restarting to no avail
only engine code there is p068a ecm/pcm deenergised to early
anyone got a clue what marvel of electronics has packed up causing my van not to start ?

Batterys need testing

[Gjinna]

Mine has 2 batteries and over last few weeks one doesn't seem to hold charge overnight but never had problems starting it when the relay clicks and uses both batteries just seems weird that it was sat ticking over fine then just stopped and wouldn't restart batteries are currently on charge so will try once they are full

[loot]

The front battery is in charge of all modules etc and they demand a lot of power, the rear battery links to the front to start it which usually works but then back to the front battery and it can't supply enough power to everything so the pcm etc shut down.
It is the Achilles heel because it can be hard to diagnose if you aren't aware of it, especially as you say the van starts.

Voltage load drop testing the batteries will tell you if any are fubar.

[Gjinna]

I've replaced batteries and like I said earlier replaced all relays I had spare off a donor loom don't get any error codes now and it's cranking quickly just won't start

[Punto443]

Could be a faulty ign switch or crank sensor?

[Gjinna]

Wouldn't crank sensor throw up an error code as presently it has none after I swapped out the relats

[Gjinna]

replaced crank sensor and cam sensor and changed out the ecm relay for a good known working one still same p068a any suggestions guys

P068A - ECM/PCM Power Relay De-energized - Too Early.

I've seen this fault previously on damaged PCM's & after failed remaps. Indicates that NVRAM write didn't complete
successfully prior to PCM shutdown. After the ignition was last switched off.

Well after putting it on a better diagnostics and standing looking at the engine while the engineer tried to start it I spotted the problem straight away.. the fuel pipe from filter to pump was leaking.. replaced and running jeepers it's always the easy things lol
