renault clio 1.2 1998 grande?

my daughters clio wont start engine turns over fine started one day but has not started since no fuel or spark immobiliser light goes out when the ignition key is turned so it seems the key is being read ok.I have tried a new crankshaft sensor and changed the two relays in the fuse box in the engine compartment along with a 30amp that had blown also no sound that the fuel pump is working when turning the key. any ideas anyone !
