Won't crank, but lights flashing across the board

The flashing check engine light means there is a serious problem with the performance of the engine. You need to get the computer scanned for trouble codes next.

The parts you replaced don't typically fail due to heat/cold cycles.You need to see if it might be the ignition coil.Make the coil easily accessable(take of the engine cover).Have a 12v test light and some sort of spark tester handy.Start the engine,let it run until it quits.See if you have spark at the coil.If not, unplug the low voltage connector on the coil,and put the test light across the connector,and crank the engine.The light should flash on and off.If it does,replace the ignition coil. If it doesn't flash,you may have a bad crank sensor,but this usually won't make it shut off,instead,it will cause it not to restart after heat soaking for a couple minutes.(I'm betting on the igniton coil).

The light is flashing because there is a problem in the system controls for the 4 wheel drive. You now need to have the control module scanned for fault codes and the correct diagnostics performed for the codes received to repair the problem.

You will need to have the electronic engine control module scanned for fault codes, there will be a code even if thelight is not on.

Do you have a check engine light on ? Common problem with Chrysler is the crank sensor, won way to check is with a scanner, connect to dlc, and goin to live data stream and watch your rpm if you have no signal while cranking that's your problem,another possible cause could be your anti theft system , is your security light blinking ,staying on or not coming on at all?

This light indicates a failure in your antitheft system, it disables the car to prevent theft. Go to this link for info and some solutions...

Check the belt latch,(the short belt you click in and push button to release). It has a sensor in it. Tap and shake it as it may have a foreign object in it. Look under the seat for the connector(s), and make sure they are pushed in all the way and that the wires aren't damaged. If that doesn't help, try disconnecting the connector. If the light and alarm are still on afterwards.....you have two choices. First, replace that part of the belt. Or, try running a jumper wire across the two contacts in the connector but I cant tell you that!!

you now need to check for 12 volt power, and signal to the coil, also be sure all you timing marks are correct, if you have no spark, unplug one of the injectors and using an led test light check for injector pulse power across the two terninals while cranking, if you have no injector pulse then you could have a problem with the ignition passlock system, or key decoder

Engine will crank up but it won,t start. engine check light comes up.

turn key on for 10 minutes until light stops flashing then try to crank car over
