Some times when attempting to turn my truck on I will turn the key and nothing will happen. I will sit there and try again and nothing. The third time the truck finally starts. Then the next time she will turn right on with no porblem. This past month the cycle of three tries to turn her on is more common. My lights still work when the car will not turn on, I tested the inside and head lights and all works good. Finally today the truck would not start at all no matter how many tries. I had to get a jump and it started right up strong. I already did the battery test where I leave the truck running and take off the negative battery, the truck still runs which indicates the alternator is good. I have replaced the battery about two months ago. I just went outside and she started right up with no problem. It's an on and off problem that I can’t figure out.
Any suggestions?
