Will not start and the security light is on

Hi,

Unfortunately, the system can't be removed. You mentioned that you tried performing a relearn process. What was done?

Also, if the key is left in the "on" position, will the light turn off after approximately 10 minutes?

I just need to know one other thing. You mentioned it starts and goes out immediately. Are you referring to the light or the engine?

Take a look through this link also. It may be helpful.

Let me know. Also, let me know if you have checked for diagnostic trouble codes.

Take care,

Joe

I left the key in the "on" position and the security light did not go out, I waited even 20 minutes and it did not go out.
The engine starts and immediately shuts down.

Hi,

You are experiencing a fuel lockout. Are you using a known good key? Have you tried a different one?

My concern is that the light isn't turning off. This could be an indication of a failed body control module (BCM) or powertrain control module (PCM). Please keep in mind, this is a theory at this point based on conditions.

What should be done is to scan the can-bus system. CAN stands for controller area network. Basically, all the different modules are tied together via a few wires. This type of scan will provide diagnostic codes regardless of the module storing them. Here is a link showing how it's done. Because there could be one or more modules at fault, I am recommending this be done.

Next, take a look at pic 1 below. This is what I suspect is happening. To test the circuit, we will need a scan tool that can communicate with the different modules.

If you look through the last 3 pics, they provide the diagnostics. Let me know if you are comfortable performing them.

Take care,

Joe
