It is possible you blew a fuse in your underhood fuse box. Likely a maxi fuse I have also attached a theft relearn procedure just to rule out a security relearn problem.

The BIG Fuses

Expert:  Tool Hut replied 11 months ago.

OK. My mistake I saw the year wrong. Look at the ECMB fuse in the underhood fusebox.

Customer: replied 11 months ago.
There is no such ECMB fuse under the hood
Expert:  Tool Hut replied 11 months ago.

There must be an ECM B fuse. It is a 20 amp fuse.

Did you try to do the theft learn?

Customer: replied 11 months ago.
No dont know what you mean. How do I do that?
Expert:  Tool Hut replied 11 months ago.

Sorry I thought I attached it. See attached. This should fix the security light flashing and may get to start so we can proceed.

Customer: replied 11 months ago.
Mr Brooks, this is not working for me. I can't download the attachment to see how tostop the flashing securty, battery and low fuel lights and fuel gage not working. The truck will start and run when the key is on or when pickup is running these lights are flashing and fuel gage not working. All this happen after I changed the battery. Im not A machanic and that's why im asking for professional help.

Hello my name is ***** ***** I can help.

Right now the truck runs ok? Just low fuel light and flashing security light?

Do you have a scan tool?

Do you have any codes set?

If not most auto part stores can scan it for free.

Please get back with me

Thank you
