This is a V6 with 173,000 miles on it which I inherited from the ex-wife’s brother a few months ago. Replaced the starter and it was running fine until recently. Now, every once in a while for no obvious reason I try to start it and nothing happens. This is after I have started it and run into town, run some errands, started it a few times with no problem. Come back, turn the key and nothing. There is juice to run all the other electrical systems - lights, radio, dash, fan. But when I turn the key to start it, silence. Then I get a jump from somebody (getting pretty good at wandering around parking lots, cables in hand, begging for help) and it starts immediately and will start the next few times I try. Then the whole cycle starts again.
