My 2000 9-5 Aero has developed an issue over the weekend where it won't start when warm, the starter motor engages without any issue, all electrics work and it runs perfectly once started but if i've been on a run and switch off the ignition it won't start again for 10 or 20 minutes. First thing in the morning it's fine, fires up like it always has.

It's due an oil service but plugs, filters etc were changed 6k miles ago.

Thoughts?

I had the exact same problem as you back in the summer, it was the crank position sensor.

Fairly easy DIY job, involves raising the front of the car, removing the undertray and the sensor is on the front of the crankcase behind the cat box.

In a garage it'll be about 20 mins labour.

Thanks Carlos, appreciate the response. I'll price one up and get it sorted.

Okey cokey, more symptoms have reared their head this evening. Whilst driving it now decides it want to kangeroo down the road for a second or two as though someone has cut the fuel supply off? So far it's only happened at low speeds under part throttle, i'm beginning to think it may be a fuelling issue.

Can anyone shed any light on this?

As has been said, CPS is likely culprit.....

but...... a failing DI cassette could produce similar symptoms.

I would agree with above. You can change the CPS from under the bonnet (I did mine), although it's a bit tight.
