I changed my battery in our 2008 Ford Edge. Car wouldn’t start. So I put old battery back. Still won’t start. Now check [engine](/topics-engine-ford/) light is on, battery light is on and oil light is on. And car doesn’t make sound when I turn my key Mechanic's Assistant: Does the light stay on, or does it blink? Light stays on Mechanic's Assistant: Are you fixing your Edge yourself? What have you tried so far? I was just changing batteries and yes I was doing it on my own Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? No that’s it jus would like to know why it’s not starting now when it did before I changed batteries

We have secuirty switches on every door ,hood ,trunk, security module receiver , igntion switch sensor ect ,any of these if failed will trigger the system the most common is battery dying or driver door lock stop working or a hood switch stuck open or key not being recognized ,the correct way to troubleshoot this is hook up a ford dealer or equivelant scanner and retireve fault codes from security module and based on these codes we can pull up a pin point troubleshoot and be accurate and what to repair or replace it can not be like the local parts store code reader that will not see the security module to read it you can check all fuses ,under hood fuse box and inside cabin in case one blew hooking up the battery try opening & closing all the doors and hood ,trunk few times in case switch is stuck and redo reset test ,other than that ,it will need a dealer scan arround $100 to hook up scanner and go from there

Well that’s sucks. Great part is it started snowing.. lol. Thanks for your help
