Can any body help!changed my fuel filter & purged the system by switching ignition on ,pumping acc pedal 5times& waited for light to stop flashing,then started engine with acc pedal to floor.I have done this process twice,draining battery on both times,recharged battery but engine still slow to start when cold(lt only starts after long cranking)it used to fire at aflick of the switch even cold once the glow light had gone off.I have only changed fuel filter,any advice apprieciated.
ps.the engine cranks fast,just feels like struggling for deisel,then after initial start.is fine for the day,untill left for 2days then problem starting again.
what is the correct size battery?thanks steve.
