Engine ECUs almost never fail but garages who don't really know what they are doing often claim its failed. I assume you meant crank shaft sensor rather than cam shaft sensor as cam sensor doesn't usually stop the car running plus you need to take the cam belt off to change it.

Yes i did mean crank,i had engine overhauled 6months after buying it and when it runs its fine,very frustrating fault at moment as once its started its fine,but not starting in morning without pushstart,just wondering if it could be minor electrical fault,dirty contact,water ingress,ect rather than expensive repair,prepared to do work myself with some advice,thanks for feedback

I would get the codes read on either FES/MES or Alfadiag these may give you a better insight into what is wrong better than a generic code reader. I've had an ecu problem on my 156 v6, it showed multiple faults on FES, camshaft sensor, crank sensor, lambda sensor and purge canister switch. ECU and lock set off ebay cured it. One of the problems I had was starting the car, if I waited until all lights on the dash had gone out it started, if I was too impatient it wouldn't :confused: Italian/German electrics :)

Got different mechanic to look at recently fitted crank sensor and he removed seal and refitted crank sensor,so far car starts fine and runs fine,but will having no seal cause any further problems as it must ne there for a reason?

You probably do have a seal in there. Who ever originally changed it probably hasn't removed the old seal so when the new one was fitted there was 2 seals so it wouldn't read correctly. Now it's been refitted with "no seal" it will be reading correctly.
