At first the Services Theft System code allowed me to start and use the vehicle with only my speedometer and tachometer working but the fuel and temperature gauge had no response whatsoever. I tried to reset watched YouTube mechanics and now it's worse no start nothing. The rest is as follows:
I left my battery left disconnected for a day, then reconnect and double check every connection, fuses, battery fully charged. When I turn the key I have inside lights that all the instrument panel doesn't light up. Doesn't crank or turn over and I double checked everything again. I'm frustrated and puzzled can't use or start the vehicle key doesn't come out of ignition unless I pressed release tab under the steering wheel column to take key out but it the same every time I insert the key. Can you please help me I'm stuck in this matter alone?

Hi,

As far as the key-related issue is concerned, check the RIM fuse in the right rear fuse box. See pic below. In addition, confirm there is power to and from it.

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

I attached a pic below showing the fuse orientation within the box. Let me know what you find.

Next, if the anti-theft light turns on when the key is turned to the run position, allow it to sit there for approximately ten minutes. At that point, the light should turn off, and the engine start.

Try these two things and let me know the results.

Take care,

joe
