Hi, I have a 172 but my neighbour's grandson has a 1.1/1.2 (not sure) 2003 clio and he came to me asking for help on this forum! Yesterday he changed the battery, pretty quick outside. But now it turns over but won't start. He's checked the fuel pipes and there is no fuel being pumped. I'm guessing this is some kind of ECU reset issue? If anyone could provide any help at all with this problem I will be (or he will) forever in your debt!
