Got in car a week ago turn the key nothing happened. Two days ago, the security light came on, now nothing. Where do I start? I got new keys, ignition switch, engine harness, ECM, TCM, TDM, starter, and alternator. I'm at a loss.

Hi,

Wow! Have you replaced all the things you mentioned? Is the battery fully charged and in good condition?

Let me know. Also, let me know if all other electrical components are working as designed. I need to narrow things down a bit. Note that if you replaced the ignition lock cylinder and key, it needs to be programmed to work.

Also, if the security light turns on, try this. Allow the key to stay in the on position for approximately 10 minutes. After that amount of time, the security light should turn off, and the engine starts. Try that and let me know the results.

Last, if you haven't already, I recommend scanning the can-bus. CAN stands for controller area network.

Basically, the different modules are tied together via a few wires. This type of scan should retrieve codes regardless of the module storing them.

Here is a link that explains how it's done:

Let me know.

Thanks for the update. Let me know if anything shows up with the scan. Also, let me know if the list above has already been done.

Hi,

That shouldn't matter. Sorry to hear what happened. I struggle to understand things anymore. I was always taught if you want something, you work for it. Destroying people's personal property for one's personal gain is upsetting. So, again, sorry to hear what happened.

Let me know.

Only codes that come up are 441,446,0036 would any of those cause this?

Hi,

The codes are related to the evaporative emissions system (EVAP). That wouldn't cause this. By chance, does anything electrical work on the vehicle? Are you certain the battery is in good condition and charged?

Let me know.

Hi,

Thank you for the update. I'm glad to know you got it running.

As far as the stalling when you let off the throttle, make sure to check for vacuum leaks being caused by the EVAP codes you have. That can be causing the issue.

Let me know if I can help or if you have questions.

Take care,

Joe
