engine problem espace MK3 DCi G9T

Hi Guys



any pointers on this ?



had one injector chuffing away, so pulled it out, re seated, new washer and re-assemble, that went ok





started her up, fired up straight away, made small rattle sound,so turned off,

tried to start again and just turns over, wont even try to catch.

tried some easy start as though maybe just needed to pull diesel through as been off road for 2 months

wont even run on easy start, sometimes it will try but just for a split second.



put the clip on and have a few errors,



DF019 - flow sensor circuit - I have the MAF & air box disconnected

DF022 - Ait temp sensor circuit - CO1 - old fault

DF052 - External Temperature sensor - CC - again think this is old fault but comes back after clearing

DF085 - Water Temp - CC - old fault like above,

Pre heat relay circuit CC1 - this is an old fault and always been fine with this even in cold weather



I did have to charge the battery as went flat being left standing for two months

don't think it holds charge like it used to, its probably 3 years old now at least



checked the following via clip



Pressure in gallery 4 Bar - thought this should be higher ?

rail pressure loop variation 298 Bar

gallery pressure valve RCO - 5%

engine speed when cranking varies between 220 and 280 RPM, sometime with easy start is tries to catch

and RPM went to about 1500RPM



Not sure what the RPM on cranking should normally be so removed TDC sensor as known problem

not very dirty, but cleaned up and refitted, but no change in recorded speed



when switch ignition on you can hear the low pressure pump run, and also you can hear the fuel running through the

high pressure pump , would this be normal ?



reading through old posts someone said cambelt slipped on theirs, would have thought I would have got

error for TDC + cam not matching up



also wondered about high pressure pump, but would have thought would have run a bit on easy start





any pointers for me to look at ?



cheers
