My 85ps mk6 swb fwd transit is having starting problems from cold or when the van is left for a period of time (half hour plus)
Once started it runs like a champ with no smoking, chugging or missing it just takes a few attempts to start sometimes and under prolonged cranking will store p1563 and p1664 which i understand are related to the injection pump control module, if i crank for a few revolutions and then turn key off and try again it will catch and when i keep cranking will start and idle lovely.
Through research on this wonderful site i have narrowed it down to a few possible culprits.
Timing chain tensioner: not ruling it out but i definitely DO NOT have any cam chain rattles any time it starts (when i changed the oil for specified 5w30 it rattled its head off untill it had pressure at the tensioner (2-3 secs) so im aware of what this particular engine sounds like with a loose chain)
Air ingress: I have changed the fuel filter for a fram item (my father works at a motorfactors and got all the service parts at a good price) which i primed with valvoline system cleaner and it started first revolution after this, although i have read the ford ones seem more reliable. To be honest im a motorcycle techy so have not spent much time around diesel engines :S and would like some pointers on where to look for air ingress/how to test.
What i have noticed is a little "misting" around injector 4 (furthest from chain) no pooling but maybe air is getting in around here?
Any help would be greatly appreciated as it drives really nice for having 122,000 miles on it
just dont want to lunch a starter motor.Thanks in advance jamie.
changed filter last night primed with fresh fuel and no change. Filter head next I reckon.
