Hi All

I am new on this forum and also never had a ford before

I have a Mondeo 2001 1.8 in petrol so is MK3

The car has been fine two days ago(driven for about 150 miles)
And today morning i cannot start the engine.

I check the light and is illuminating for 3 seconds and going off so seems like the IMO is working fine. Engine is turning but no chance to start it. New battery has been fitted as well but no results

What can be the cause??
