If the fuel pump stops and a rap gets it going again then it will chatter
away for a couple of seconds or more, not just give a couple of clicks. A
blocked petrol cap (for unsmogged cars) will cause the symptoms you
describe, if you remove the cap and get a 'whoosh' this is a fair bet. If
you have a smogged car I believe blocked hoses will cause it.
