1.9 DG Intermittent starting problem
Posted: 21 Oct 2014, 14:09
Hi volks
My van has always started well - almost instantly - from cold (except when I had a weak battery or other issues). Also it starts well when hot - like after stopping for petrol. It has always been harder to start when warm - if left standing for about half an hour / an hour. Then it takes a bit of cranking, about 5 - 10 secs, with perhaps a dab on the accelerator pedal. In the last few weeks it has begun to be difficult to start occasionally from cold, needing several 10 second bursts of cranking, with a bit of a rest. Once it catches it sounds a bit rough for a second or two, then runs for the rest of the day as if nothing had ever happened. It idles smoothly, pulls happily up hills, and generally behaves very well. Fuel consumption seems normal. One or two years ago I replaced the battery, and now it almost never does its old trick of just clicking when the key is turned. That click never worried me particularly as it just needed turning again, once or twice. I think it clicked about a month ago, just once. I replaced the fuel pump and hoses in July which had been causing the occasional hiccup. A month ago I replaced the spark plugs after the first time it didn’t start, and thought I had sorted the problem. This morning (heavy rain) it took several minutes to start. When I tried it just now (lunch-time) it started instantly. I think it might be electrical as occasionally at the moment when I stop cranking, I can hear it fire. I suppose this means the ignition system is getting the power the starter was using.
I would be very grateful to hear if anyone has any ideas?
