Lately, I have had some difficulty starting my truck. It will usually start, but it will be really weak. Every once in awhile, when I try to start it shortly after I have turned it off, I have to jump start it. But if it sits for a couple of hours or more, it will start perfectly. Then, this evening, when I went to run to the drug store, I came back out to my truck, and it wouldn't start at all. Nothing, no attempt to turn over at all. The radio worked, and the power windows would go down, but nothing from the engine. When I turned the key in the tumbler, I didn't feel much pressure, like it was stripped or something. I was able to put the key into the start position, and do the trick where I pop the hood and put a screw driver on the two screws to get it started. But then it wouldn't let me get it into gear, so it still is sitting at the drug store. Hope this makes some sense. Any suggestions or thoughts on what could be wrong? Thanks for any replies.
