Help, Intrepid quit working!

i have a 98 dodge intrepid es 3.2l and i drove to my moms house, when i go into the car to start it back up it wouldnt start. i sounded like it will turn over or just about to and it stops and doesnt turn over. we have replaced spark plugs, fuel pump, battery, oil change has been done, and fuses has been changed. we dont know what to do anymore and all the mechanics i have talked to are stumped. i need help. any and all advise would be helpful.:banghead:

in my old accura was a broken wire into the UCM.
