starting problem

There is a starting problem in my car, I wanted to consult you because I do not understand these works.

The dynamo of the starter motor with its coals changed in the nights. After that, this trouble started.1 It happened 2 times today.

My car normally gets a starter, but sometimes the first After not getting the first starter, it is not possible again. It does not work for a long time. I press the starter for 15 20 seconds for a long time. Sometimes it does not, and sometimes I have to do this 6 and 7 times. My friend had done it when he wasn't working for the first time, he said he was strangled, he said he didn't work from him, but today I parked somewhere when I returned he did this again.

.yanık It smells like smell and it smells of raw gasoline after the car. I wonder if there is a problem with the starter motor or the problem is something in the gas pump. But I normally think it will not work in the gas pump. > Thanks for your comments in advance .. 19:37:22
