I hit a pothole yesterday and the car cutoff and wouldnt start back up after getting towed home this morning i changed the crankshaft position sensor and the cam sensor also but realized that the car wasnt getting any fire and was wondering what could have caused the car to short out like that

The first thing to do is check for diagnostic fault codes. Chrysler makes that real easy. Cycle the ignition switch three times from "off" to "run" within five seconds, leave it in the "run" position, then watch the numbers show up in the odometer display.

Next, check for spark during cranking. If there is no spark, you have to determine if the automatic shutdown (ASD) relay is turning on. The easiest way to do that is by measuring the voltage on the wire that feeds the ignition coil or coil pack, (you didn't say which engine you have), or any injector. Typically that is a dark green / orange wire. You should see 12 volts there for one second after turning on the ignition switch, and you may hear the hum of the fuel pump for that one second. What's important is whether that voltage comes back during cranking.
