last thursday my 2005 dodge neon wouldnt start, i got a jump and had my battery tested and rplaced it. Later that day i was driving down the street and my car got jumpy and then was stuck in first gear, engine code p0700, (which i know is the tcm) had that replaced three moths ago. i unhooked my battery for two hours, then took it for a test drive my gears had all returned, drove for ten minutes and problem returned. Now it wont start, there is no click even and i have lights, radio, and door alarms working still. where do i start to fix my girl? please help!!!!!

 

Have you had the alternator tested?
Have you tried to jump start the car again?

 

havent tested te aultinator no, did re jump it and it started the molex to the ecu was lose, but now, the battery i just bought wont hold a charge it acts lik the battery is disconnected?? the tcm isnt messed up anymore that was the bd connection from the molex im confused as hell

 

My neon had similar symptoms. Engine wouldn't even turn over, but all the accessories powered on no problem.

Turned out to be a corroded engine ground.
