2002 despatch 2.0hdi engine cuts temp flicks high

wotcha all
got a 2002 citroen despatch

on start up
the temp flicks to high
engine stop flashes
engine cuts out momentarily but keeps running
it is irratic some times fine other times non stop juddering as the engine cuts out, the radiator fan cuts in when this happens. it does it even without the engine running
also some times when i turn the engine off the fan comes on and keeps going

it has now crunched the crankshaft pulley. i managed to get where i was going and as a get me home
welded the crank pulley back together

so far i swapped out the
fuel pump relay
glow plug relay
engine temp sensor
but its still the same

i did strip the loom from the ecu
to the engine but found no visable faults
at the mo i have it up in the air
i checked all the pin connectors
i had the use of a obd11 but it showed nothing

i have changed the fuel filter
( twice)
that made no difference

the van has just over 40k from new

i cant afford to take it to a dealer

i found last week end when the pulley went pop because of the juddering engine, that below 30mph it was constant around 50mph less or i couldnt notice it as much

the fuel pump relay gets warm
also today i noted one of the blue relays in fuse box behind battery was clicking as the rad fan cut in and out

the engine runs as it should no over heating no loss of coolant
oil level is good
any one had this ??
cheers
