Please help - starting problems!

[Micramouse]

Hello,
My micra is a 1998 Ally Ltd Edn and its driving me mad!
Most days it starts perfectly then for no reason it just will not start, no power to the plugs/coil, battery has loads of power, I can wait, say 1 hour, then maybe it will start, its just pot luck.
I am sure its something to do with the immobiliser - can anybody give me some advice please?

Thanks
Barry

check the fuse box i had the same problem had to cut off the injector fuse and put some spades on the end of the wire and put the fuse on that, its becuase the fuse box gets corroded especially the injector fuse just have a look worth a try!
