Hi,
If the car has sat for a week or so almost always on first start it will fire up immediately, presumably on the CSV fuel, and then struggle and bog down for several seconds, sometimes dying, before bursting back into life and then running as normal.
I had some running problems recently, now fixed, so while the fuel pressure testing kit was plumbed in I measured how long it took the primary pressure to come up to spec: after sitting for maybe 10 days it took 7 seconds! It holds rest pressure very well so I don't think there is a leak in the accumulator.
I seem to remember a post where somebody here did the same test and measured about half a second to build up pressure. Big difference, and might explain my bogging down when it's first started.
Any ideas? Anybody with any experience of the accumulator failing in this way? I.e. no leak but for some reason takes ages to come up to pressure.
Another thing I noticed was when depressurising the fuel system by operating the frequency valve (rather than opening the lines under rest pressure). You could hear the accumulator "clank" over and over as the FV let the pressure back into the tank.
Cheers,
Mark
