ive just replaced the clutch disk n now stumbled onto more problems. when i try to start my car, it just ticks n sounds like its coming from the radio. also when i turn it to the on position, no engine or warning lights popup other than the brake warning light.

i replaced the main relay fuse under the dash, found the ecu code to 6 flashes which is "COOLANT TEMPERTURE." idk how to resolve this, i hate to just junk it even tho i got for like $300 also put alot time in it, car was running great previously when i bought it and why it was cheap cuz of the worn clutch. any help would b appreciated.
