Two months ago, I had a problem on intermittent no start and no crank in my Mazda 323f 2000 AT model. When I brought it to the shop, they found out that the problem was the starter and that the brush needs to be replaced. After replacing the brush and re-installing the starter, the problem goes away.
Now, I am having the same problem again. When I turn the key, I see the lights on the dash board (bright so I am assuming this is no battery problem) but no cranking happens and of course the car won't start. Also, I noticed that the key got stuck for a brief moment and I cannot remove it in the keyhole.
I tried turning the key again and to my surprise, it started at the first crank. Now after a few minutes, I tried turning off the engine (I was able to remove the key this time). And then another minute I tried starting it again and the same no crank, no start happened. I tried starting it again without removing the key and it started in the first crank.
If anyone can give me advice on what to look at, diagnosis I can try to get to the problem, that would be great. Do I need to return to the shop who did the brush replacement?
