r reg micra wont start! help!

I have a 1998 1.0l nissan micra and it wont start in the
morning. once it is started it will run for the whole day
but leave it over night and the next morning i have the
same problem. sometimes it starts if i remove the fuse
that sends the petrol to the engine but recently this
hasnt been working and the battery keeps dying. my
mechanic friend took the spark plugs out and theyre
soaked with petrol suggesting there's too much petrol
getting there. ive changed the spark plugs, got the
sensor that is supposed to stop too much petrol getting
to the engine and also replaced the part that measures
the engine temp (i think, i didnt do this myself!) but i
dont know what else to do! ive already spent so much
money on it changing different parts. can someone please
heeelp!

Two on e bay looks like there are two types both under £10
