First need to know the exact engine size. The different engines have very different ignition systems. Second, need to know if anyone has read and recorded the diagnostic fault codes. Disconnecting the battery will erase any codes, so if that was done when the alternator was replaced, there might not be any valid codes set yet, but check anyway. Chrysler makes 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 watch the code numbers appear in the odometer display. Those codes never say to replace a part or that one is bad. They indicate the circuit or system that needs further diagnosis, or the unacceptable operating condition.
If you have a four-cylinder engine, be sure to find out if it is the single overhead cam version or the double overhead cam version.
While you are gathering up this information, since I do not know how experienced your mechanic is, tell him to determine if the automatic shutdown, (ASD) relay is turning on during cranking and staying on steady. The easiest way to do that is to view its "state" on a scanner, but he can also use a test light to check for twelve volts on the dark green/orange wire at the ignition coil pack, any injector, or either smaller terminal on the back of the alternator. Knowing that will tell us where to go next.
