Posted by JustAnswer at customer's request) Hello. I would like to request the following Expert Service(s) from you: Live Phone Call. Let me know if you need more information, or send me the service offer(s) so we can proceed.
Expert:  Virtual Wrench replied 1 year ago.

I can call you in a few minutes but let me first ask if you have tried to jump start it and if so, do you have a volt meter to use for some simple testing?

Customer: replied 1 year ago.

Expert:  Virtual Wrench replied 1 year ago.

Thanks,

When you turn the key just to the on position, does the security light come on for a few seconds then go off?

Customer: replied 1 year ago.
No, it stays on
Expert:  Virtual Wrench replied 1 year ago.

Thanks!

We might be able to reset the security system and not even need a phone call. Try this first and if it still doesnt start i will call you.

1. Turn the key to ON and attempt to start the engine and release the key to the ON position.

2. The SECURITY light will illuminate. Wait 10 minutes until it turns off.

3. Turn the key to OFF for 10 seconds.

4. Turn the key to ON and attempt to start the engine. If it starts and run, the system has reset. If it doesn’t start or run and release the key to the ON position and complete the rest of the steps.

5. The SECURITY light will illuminate. Wait 10 minutes until it turns off.

6. Turn the key to OFF and wait 10 seconds.

7. Turn the key to ON and attempt to start the engine and release the key to the ON position.

8. The SECURITY light will illuminate. Wait 10 minutes until it turns off.

9. Turn the key to OFF and wait 10 seconds.

10. Try to Start the engine

Tried that and the light just stays on
Customer: replied 1 year ago.
For some reason it won't let me pay for a phone call
Expert:  Virtual Wrench replied 1 year ago.

Lets try one more thing.

Remove both battery cables and hold them together for 1 minute then reconnect them and see if it will start. This will reset the vehicle computer and works sometimes.

Customer: replied 1 year ago.
Tried that also
Expert:  Virtual Wrench replied 1 year ago.

Does the key have a security chip in it?

Customer: replied 1 year ago.
I think so, how do I tell
Expert:  Virtual Wrench replied 1 year ago.

It should be black and have a small bump on it.

It most likely does. Do you have an extra key to try?

Expert:  Virtual Wrench replied 1 year ago.

If not, using the key, first lock, then unlock the driver side door and see if it starts.

Customer: replied 1 year ago.
I only have one key and it doesn't have a black bump o it
Customer: replied 1 year ago.
I had the battery in hooked for about 3 hours today installing a light but when I tried to start up the truck when I was done nothing happened. But my light works
Expert:  Virtual Wrench replied 1 year ago.

Did you mean the battery was UNHOOKED for 3 hours

Expert:  Virtual Wrench replied 1 year ago.

See if it will let you accept the phone call offer this time please.

Customer: replied 1 year ago.
It won't. I paid the same way to talk to you.
Customer: replied 1 year ago.
the battery was unhooked
Expert:  Virtual Wrench replied 1 year ago.

Hmm,,not sure why thats happening. I dont have access to admin controls. I will email them and see what they say but in the meantime......

Just so i have it straight.....it was starting just fine until you disconnected the battery when replacing whatever light it was....which by the way, what all did you do and what light were you working on?

Customer: replied 1 year ago.
I installed a light bar and the only thing I unhooked was the battery. I haven't started the truck all day though
Expert:  Virtual Wrench replied 1 year ago.

Thanks,

I think we can rule out it being a key issue.

It sounds like the TDM (theft deterrent module) is preventing it from starting and without a factory level scan tool, we have pretty much tried all the shortcuts that are available. Hate to say it but it's going to have to be scanned in order to hunt down the fault.

The only thing i can suggest is to try to disconnect both cables again and hold them together for a couple of minutes, and if that doesnt work try the "relearn" procedure i sent again....

Also try locking and then unlocking, the driver side door, and passenger side (if it has a key cylinder).

If you have a key FOB you can try using it to lock and then unlock the doors.

If it still doesnt start it will need to be scanned.

Man i really hope it works for you because we sure tried all that we can.

Best wishes my friend!

Larry
