I need help with my car! My car wouldnt start one morning the starter motor didnt fire but all electrics were on and the fuel pump was going, then i took the key out and tried again and it started fine. it did this a couple of times. one morning it did it and wouldnt go at all, so i sent it to the garage and they replaced the ignition barrel for £164! they cleared all my fault codes aswell. now its doing it again but i can here the relay buzzing away when it doesnt start! they replaced the relay and still no good! they said they have ran out of ideas with it! has anyone had the same sort of problem!? i need help!

It could be an immobiliser fault.

I would check earths to engine and remove little wire from starter and clean then replace, immobiliser wont stop it cranking.
