Most Chrysler cars do have an anti-theft system that can cut out the engine.

I would call the service department, with your VIN handy, and see if yours was equipped with one, and what you need to reset it.

If that isn't the problem, your EGR valve might be bad, or the sensor for it. I've seen a lot of cars where if either the valve itself, or the sensor are malfunctioning, the car won't run properly.

I would also check your MAF and IAC, as those can cause the car to not run.

If you can, get an OBDII code scanner, and pull the codes from your car, they might give you a more specific place to look. (Most parts stores will let you take one home, you put a deposit down, and get it back when you bringthe scanner back to them)

The Fuel Pump is Located inside the Fuel tank. The tank will need to be Dropped for this Repair. The Average cost of this Repair is around 500.00

SOURCE: harmonic balancer wobble will it cause any more

yes besides causing a vibration while driving and possible throwing belts the balancer out of balance can cause problems with the lower end crankshaft such as seal leaks ,bearings and if breaks off or apart can cause damage to engine and body
