Hi Everyone, thanks for the help.

I have replaced the battery (was 3 years old) and still won't start.

I can get pressure around 25000 psi when driving maybe a little higher, will check tomorrow. The maximum whilst cranking is around 1900 psi.

The suggestion of a faulty rail pressure sensor got me thinking so I disconnected the sensor and the car starts perfectly in about 1 second. Every time! My OBD2 logger then reads 24000psi with the sensor detatched (guessing that is open circuit for the sensor)

With the sensor disconnected the car drives pretty well today, maybe losing power at high revs....

So does this mean the sensor is faulty?
