Yes i did .
And even before i uninstalled it,it still could not read.
A friends OBD scanner a new one.
Four mechanics came by to scan it and they could not read or find the problem.
One mechanic told me to open all door ajar and press it in.

check door switchs for working if you have enough knowledge to remove them see if wire is broken on one of them. check relays in picture. if those are not the problem then have a mechanic scan for codes to check GEM module. I am assuming they are staying on all the time because your description is vague.

When the battery is connected the theft light comes on .
I plug in the key the theft light stays on.
Turn on the car it cranks but cannot turn on and running .
I uninstalled the alarm system and it is still on .

That would be the factory immobilizer. If you removed the factory alarm parts you will need to reinstall it, then have the system tested to determine why the key is not recognized.
Just taking it out shuts down the computer so it will not run.

Did you reinstall the parts you removed in the earlier question? Do you have power and ground at the data link connector? Without the correct power most scan tools will not connect. Which tool are you using?
