Definitely not a fuse problem. Normally you need to check for fuel pressure and injector pulses too but that's hard to do without a special test light. You must not get stuck on the first thing you find missing; spark in this case. There's two things you can do to prove if I'm on the right track. The first is to test if the automatic shutdown (ASD) relay is turning on The easiest way to do that is to poke a test light into the cavity on the ignition coil pack with the dark green / orange wire, or that same color wire at any injector connector. You can also test on either of the smaller terminals on the back of the alternator.
You will find 12 volts there for one second after you turn on the ignition switch, then it will go back to 0 volts. You should hear the hum of the fuel pump at the same time. Next, that voltage must come back during engine rotation, (cranking or running). If it does not, suspect the crankshaft position sensor or the camshaft position sensor.
If you're lucky the Engine Computer will have had time to detect the missing signal if one of those sensors is bad, and it will have set a diagnostic fault code. Chrysler makes reading codes yourself real easy. 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. The first series of flashes is the first digit of the code. After a short pause the second series will flash for the second digit. After a longer pause, the next code will flash the same way. Code 55 will be the last one. That just means it's done.
