so its just the filter you filled with fresh diesel?
can you explain how you pressured it back up, and where the normal diesel came out?
as with most net based diagnostics, we dont know your capabilities and procedures, and as much info as possible is required in order to be at least half helpful.
pages could be written on what to do and how to do it, but it saves us all time if the details are there in the first place.
useful bits to be going on with-
-remove glowplugs and check operation with good battery
-check operation of glow plug circuit on motor
-disconnect all injector pipes and crank over till fuel spurts out
-ensure a decent battery and good cranking speed.
-replace injector pipes and crank till vapour comes out of glow plug holes
-replace glow plugs, follow glow plug cycle and crank engine
-note colour and density of smoke emitted from tail pipe
-note any attempts at firing
-avoid easy start!
