Another non starter!

Hi all,
New to clio ownership but long time petrol head. He is one has me stumped.

Car was running fine (front brakes overheating but that seems to be a regular issue) then completely cut out. No bangs or excitement, just dead.
Now I have a flashing red "stop" light (owners manual says coolant temperature light) and occasionallyrics the immobiliser doesn't turn off. When it does the engine turns over but doesn't fire up.
Also when I first turn the key on, the relays in the engine bay tick on and off for 2 or 3 seconds.
Anyone had a similar issue??
Any ideas what I can do to diagnose?
For clarity it's a 2002 clio 172 cup in blue ;-)

I've had similar sort of problems with one of my older clios.

Cleaned up all the earths and battery terminals and that sorted it.

Worth a go as it's free.

Thanks, will give that a go.
Tried somethings as follows,
Changed coil pack no change.
Cleaned Crank angle sensor
Check voltage at fuel pump and getting 2v on one pin and 5 on another?!
Can someone confirm which way round the relays are as one has 12v supply with ignition one doesn't.
