I have this starting problem. When I turn the key part way, normally, there is an "electrical humming sound" and then a "positive click sound". Then I turn the key all the way to start the engine.
But sometimes when I turn the key, there is no "electrical humming sound". When this happens, the engine will start and crank, but then it will just stall.
I think the problem is with whatever that creates "electrical humming sound". I guess it is the solenoid for the starter, but I am not sure. Anyone can help me?

Thanks
