2.5 (4)cylinders)= aprrox. miles - 137,000. automatic tranny. today flat out won,ty start and key stuck in ignition switch. battery about 1 year old and connections kept clean.. cat converter is brand new . turn the key and got only one click. even with the key in the "on"position no lights on the dash and no accesserys were working. this happened a couple of times in the past ,but at least it would try to start and eventually did start.

Check negitive battery cable connection down on trans...

Had the same problem on mine. Do you have the stock battery in it? If so replace it. I ahd my stock battery just up and die when i had 50k on it. But havent had a problem since.
