When I try to start my car when the engine is hot (Can only be after 15 minutes of driving, then turning off and then re-starting) car can make a clicking should like it is trying to start but the engine will not keep going. The only way I can get it to start is to put my foot on the accelerator, but then the engine will stop again when I take my foot off . If I wait an hour (to let the engine cool down) then try to start the car it will start easily. A very frustrating problem! Does anyone know how this could be fixed? Could it be something to do with evaporation of petrol in fuel line between tank and motor? Or to do with thermostat? Really need your help!
