Had the car a few months and it's been running fine until tonight. When I tried to start the car it would turn over then die unless I kept my foot on the gas, but would die as soon as I took it off. Took a quick look under the bonnet and could hear a buzzing noise from the right hand side on the engine, sounded electrical. Dissconected the battery and it stopped, connected the battery and the car started again no problems. Drove it home and checked under the bonnet again and the noise had returned. Think the last owner had a similar problem with the crackshaft sensor but this was replaced
