Clio 2: put the key around and nothing goes on, but the lights all go on

Hello to everyone,I hope someone can help me.The following problem We drove normally he jerked a bit and used up more fuel than usual.Want to go where the next day?What happens?Never the engine turned so the next day I called Adac to allow the Clio to be towed in a workshop, arrived at the workshop and after a first assessment, it could be the ignition coil.The car driver on the scrapyard a fetched and built in.What happens?Nix A In the same day a locksmith was called to see if the immobilizer is active.No everything ok.After that the car was read out.No mistake.At the end of the day we were told the car does not get a spark, but why not?Ochja that’s a longer search but for that we don’t have time to scrap the car after all.So we had Adac called home again.Now eat so when you turn the key no more and the clock goes with what was not before.O I’m desperate, I don’t have any money to go to a Renault workshop that will go into the 1000 until you find the mistake.I’m a woman and have no idea.Now I hope on this path and hope here are some of the tips that can give me.Sorry for the long text and for the one or other spelling errors Vg
