Have you managed to get the car on a diagnostics reader yet? Dodgy crank sensors are a known cause of starting issues but this usually only when they're hot and they don't show up as a fault on the diagnostics reader. Something else to consider looking at.

When the crank sensor went on my 145, the car wouldn't start when cold, but when it was running it would run perfectly.

Could also be the cam sensor, especially if the cambelt has been done recently, but this usually throws up the Engine management light.

Well, back after a few months and will try to fix the car again

Last night the car dont start, after verify some things, i disconnected the sensor that are close to the MAF ( i think that its an temperature sensor ) and the car Engine start. After that stop the engine, plug the sensor again, and the Engine start without any problem.

How is that possible? maybe i need to change the sensor?
