Engine cranks but will not start

Hello. Are there any trouble codes stored in the computer? If your car has a digital odometer, you can turn the key on - off - on - off and on again and it should give you the trouble codes. Write them down or report them here. If that doesn't work, then you'll need a OBD2 scanner ($35.00 on Amazon or borrow one from a gearhead/tool junkie friend). Here's the guide on running a scan using a scanner:

If there are no trouble codes, given what you've done so far, I would suspect that either there's some security issue going on which is causing the engine computer to shut off the fuel injectors or the fuel pump simply isn't putting out the pressure needed.

You can take the key along with the title to the car down to the local Chrysler dealer and they'll check the key for you, either free or very cheap, and make a new one if necessary.

As for checking the fuel pressure, you'll need a fuel pressure gauge for that. You can borrow one from one of the chain auto parts stores with a refundable deposit. Here's a guide on running that check:

With the key on, engine off, this pump should put out around 58 PSI. The car will not run with much less than that. The attracted images are AllDatas information on field pressure testing specific to this car.

So look into those possibilities and let us know what you get. Again, if there are codes, we need the actual P numbers, not just their translations.
