After leaving my 850 T5 for a couple of weeks I came back to a flat battery (perhaps discharged through the alarm?). Not a big problem I thought - I put the battery on charge over night, re-fitted, and wouldn't start... After replacing battery, plugs and distributor cap it has finally started - but not well at all. It seems to require keeping the starter motor going for anywhere between 10-20 secs before it finally fires and runs. Once running it seems to run fine and smooth. Previously it wasn't brilliant but always started reasonably well. Any advice / pointers? Best wishes, Graham
