It wont start!

[Enigmatic]

I've a clio 00reg just lately after having problems with the keys (had to have a new one and it be re-coded) i've had nowt but trouble, i left it standing last night while i just popped into my friends, came to start and it just keeps trying to turn over and wont spark im thinking a lamba sensor, dodgy coil, faulty earth, imobiliser on way out?
Please help

tell me its something easy and not costly as i've just shelled out for a water pump, hose, cambelt change

ghey renault electrics!

My first clio had this problem, i replaced the starter motor but it still kept doing it, turns out it needed a tdc sensor and loom.
