I recently bought private sale a ford cmax 07 auto petrol 2l with only 53000 miles on the clock. After owning it a week it started coming up with fault lights, they would flash on and off so quickly I couldnt remember them all but the power would drop and the radio would quieten then it would all come back on again and be fine. Then it intermittently wouldn't start, like no power, it wouldn't turn over or anything. A mechanic thought it might be the sensors and took a look for corrosion but said they were all fine. The AA man who came out once said it was likely the immobiliser so I stopped locking the car. Today it flashed up its usual warnings but this time they wouldn't go, I stopped at a local shop left the car unlocked but it just wont start, the brake pedal wont depress and theres zero, nothing at all coming from the car. Any idea if this is one fault or several? Or what could be causing it? I cant take it back it was a sold as seen but I am just about ready to dump it!
