Twice recently my 9000 has died on me when driving. The first time I had been pressing on somewhat, fast overtaking, and I got a little warning hesitation before it died a mile further on. Warm conditions for the UK, say 30C, but not extreme. I could restart for a few seconds, enough to get off the road luckily. Similar experience second time but I was just strolling along the motorway at 75. I made it off and into a service station by the skin of my teeth
On both occasions I let the car cool down for 10-15 minutes and it started and drove absolutely fine after that. I pulled the plugs out and they looked really good. I have a new DI and plugs with perhaps 2,000 miles on them
Reading this board I found two possible culprits - the crankshaft position sensor and the fuel pump. I measured the resistance for the CPS at the Trionic connector and it was 585 ohms, dead in the middle of the required range. So first question - can the sensor fail intermittently? It's a cheap part so I guess I will replace it anyway
Fuel pump - I've had no symptoms of low fuel pressure, and I had more than half a talk of fuel both times. Can the fuel pump also give intermittent problems? The car has 174k miles - so do I replace it because it'll fail soon anyway?
Finally, I didn't think to undo the fuel tank cap to see if these was a vacuum there. Maybe next time - but next time I might no be able to get off the road so easily, so I can't really risk using the car until I resolve this
I'd welcome any thoughts or advice - thanks
