On my way home from work today the car cut out and a light came on (looks like a box with wiggly lines coming out of it) which is apparently an exhaust temperature warning light? Upon closer inspection of the car, I found the sump plug had fallen out and I had no oil. I have since sorted this and filled the engine up with oil again.

However, the car still won't start and this warning light is still on, any ideas?

I have attached a picture (very bad phone pic, you can just make it out though) of the light if its any use....

Hope you can help,
Kev.
