Yaofeng,
I still wouldn't rule out the CPS. I spent almost a year chasing the same symptoms. It gave me a real headache, since as soon as I wanted to start measuring the car would start right away. Idle was a tad rough, becoming progressively worse on quick acceleration.
After a year it became bad enough so that I had a chance to do some measurements, and found the +30 and +15 side of the FP relay were both okay. the ECU didn't put the +15 to ground, pointing to the CPS.
I replaced the CPS anyway, no more problems, smooth running.
Keep in mind that the ECU gets the RPM/ timing from the CPS, so expect the car to run rough if it doesn't function properly. There's a lot of different ways a part can fail.
You might have the ECU codes read, although I am not sure about the trionic fault registration storage, but my motronic 2.8.1 system had the no-starts registered as a CPS failure when the dealer did a scan.
regards, Jan Geert
