Will not start

First thing is try a new fuel filter. Then if the problem still happens, have the trouble codes read. Listen if the fuel pump runs or not when the key is first turned to run, for about two seconds. If not, check the fuel pump fuses and if okay, try a new fuel pump relay and check it again.

What have you checked so far? Was the battery recently disconnected or run out? Have you checked for spark and fuel pressure? Do you hear the hum of the fuel pump for one second when you turn on the ignition switch? Have you read the diagnostic fault codes? Do you know how to do that yourself? Will the engine start and run if you hold the accelerator pedal down 1/4"?

Forget the fuel filter. That is a dandy suggestion for other brands of vehicles, but other than for diesel engines, you will never solve a crank/no-start or a running problem on a Chrysler product by replacing the fuel filter.

This sounds like a crankshaft angle sensor that is going out. When the engine wont start does it have spark? Here is a guide to show you how to check
