yeah not the same make tho but i leave the fiesta disconnected and the saff connected.. as soon as the jumpleads go on to the battery it starts first time.. even without the leads on and engine off the electric windows still go up and down same speed as connected to another car so i no the battery is holding the charge.. and when running the alternator is charging.. just the car only wants to start when connected to a running motor.. has always been an intermittent thing sometimes will fire up straight away then turn off go to start straight away and the starter dont even attempt to turn but you can hear the tone of the fuel pump change as if the starter is still drawing power.. maybe a box of matches will help?
