2005 transit MK6 problems + codes

[Higgins420]

hi, i have posted my problem on here previously but since then the van has been sat and thought id try and start again from scratch. its a 2005 hightop 2.4 diesel duratorq with 130000 on it.
it ran beautiflly for the firstfew months that i had it, then one day i parked up outside the shop and was in there for 5/10 mins, when i came out it turned over but would not even try to start.
called the RAC and did his best but couldnt get to the bottom of it so had to tow me home in the end, when he sprayed easystart in through the airbox it started so it seems to be a fuel issue.
when i got it home i went through every fuse and they are all fine, pulled apart every connector that i could fine and cleaned them up (they were all clean anyway and had a coating of white grease) at the suggestion of someone on here i pulled the ECU out and cleaned out the connector and ensured it was dry as a bone.
when i turn the ignition on the coil light flashes intermitantly, like morse code lol, i will try and attach a video - it is solid on for a few seconds then off and the same again twice more, then flashes once but quicker then twice in quick succession then the cycle seems to repeat.
i really need to get this sorted out now as the van needs selling and really dont wanna sell it as a non runner :/

here are the fault codes that the RAC emailed me, a hell of a lot considering how well it was running and how suddenly things went wrong !

start with timing chain side

ignore most of them codes
