My usual suggestion of find a better mechanic would seem to be a waste.
Clearly there are none where you live.
And though diagnostics are helpful they are not absolutely needed.
Not if the system is understood.
And I'm assuming either the 1.3 or 1.5 petrol?
That actually makes it a little easier.
So after normal start up it cuts out after 3 seconds,
Is that dead stop as if the key has been turned off?
And how long a time goes by before it can re start?
And when it cuts have you checked for a spark at the plug tips?
When it cuts if fitted does the rev counter register anything when you crank it over?
Answer these and we can move along.
