We are getting crossed in the terminology. If the starter is spinning the engine normally, that means it is "turning over", aka "cranking". That eliminates one type of "does not start" that confuses a lot of us. You have what I refer to as a "crank/no-start" which means the engine will not run. Typically that means spark or fuel pressure is missing and we have to figure out which one that is, however, loss of spark on this engine accounts for about two percent of crank/no-starts, loss of fuel pressure accounts for about three percent, and by far the most common cause of this problem is a loss of both spark and fuel pressure.
It sounds like you checked for spark already and found it to be missing. Fuel pressure is a little tricky and may appear to be okay, but that is usually a false test result. There are two things to do to get started. The first is to read and record any diagnostic fault codes. Chrysler made doing that yourself much easier than any other manufacturer. Cycle the ignition switch from "off" to "run" three times within five seconds without cranking the engine, leave it in "run", then count the flashes of the Check Engine light. Herei s a link to a better description and the code definitions:
Next, we need to determine if the automatic shutdown, (ASD) relay is turning on. Look for the wire that is the same color at every injector and at the ignition coil pack. That should be a dark green/orange wire. Use a test light and poke the probe through the rubber seal around that wire. You can also use either of the two smaller terminals on the back of the alternator if you want to. Now turn on the ignition switch. You should see the test light turn on for one second, then turn back off. Next, what is important is if that light turns back on during cranking. Let me know what you find.
