Does not start but turns over

Have you checked for sparks? I would say get a spark tester and check all of your cylinders for sparks. Here is the tester that I use: https://www.amazon.com/Lisle-20610-Inline-Spark-Tester/dp/B0002STSC6/ref=sr_1_3?ie=UTF8&qid=1501325755&sr=8-3&keywords=spark+tester

You can get it at the local parts stores as well, but it will cost you a few bucks more.

Also, quite simply, have you checked the fuses? A blown fuse can wreak all kinds of weird havoc.

Well you said that there is fuel. So I am just trying to narrow things down a bit. At 140,000 miles, there are a lot of possibilities. You could be getting fuel, but not enough fuel. So we check sparks and see. Another way to check is to spray some starting fluid into the air intake tube and then try to start it. If it fires and almost starts or does start, then the problem is fuel delivery. If it does not make a difference, then the problem has something to do with sparks.
