Car wont start.
 

Hi.
I went on holiday and came back and my car didn't start.
I tried jump starting it and it tried to tick itself over and then after multiple tries it just died and wouldn't try anymore.
I called out the RAC and they said that it might be something to do with the keys. I took it to a local garage to try and reprogramme the keys and it didn't work. I then took it to a ford garage and they said it might be a fault with the ECU and quoted me £1600 after paying them £75 to tell me what the problem 'might be'. I'm clueless as what to do, and it's really starting to frustrate me now. Can anyone help?
