Good afternoon and welcome to JustAnswer!!

My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 19 years and I will do my best to help.

Thanks for the request!!

I see that you have a 2007 Pacifica but you didn't what engine you have.. I take it you have the 4.0L since you said the timing belt broke.. It looks like you had some bent valves in which you removed the heads and repaired them and now it won't start. Let's see if we can get you fixed up...

  • What is the compression of the cylinders?
  • Do you have spark and fuel psi?
  • Do you see a red security light on in the dash?
  • What codes are in all the modules, PCM, BCM, SKIM, etc

Talk soon,

Hi Brad, i was away and back now. First a correction it is 2005 3.5L and the only code that come up now is PO499.
the compression is ok now, no spark, no fuel pressure. when you turn ignition switch to start noting happen.
got the information that the that the previous did repair on the starter motor. Main people and also the local dealer conclude that ECM is the faulty. is a coincidence that the car went to a shop for engine repair and won't start after repairs because of ECM failure. The car came to us starting and driving. Now after the repairs the car won't start again. to me it should be something else.Note when starting noting gets power. let me know your thoughts
