My car had trouble starting when it was hot. It would crank but not start until it cooled down. It wanted to shut down on me. Now it desnt want to start wether its cold or hot. It cranks for a while I gently press on gas pedal t help I start and once it starts a cloud of smoke appears and smell like gasoline. But once its running can drive it with no problems doesnt sputter. I changed fuel pump main relay, fans radiator spark plugs and wires. But once I shut it off and try to start it again it has the same problem.
