how long did you do the relearn, 10 mins ?

Id double check all the fuses. then if they are ok insert the key and turn to the 'on' position, wait 15 minutes.

Does the anti theft light come on, or flash?
If the light stop flashing or goes out, turn key off(after 15 mins) and wait 2 minutes and then attempt to start engine.
If this doesnt work, it must be either your antitheft module, or your instrument control panel is crappin out.
Let us know if it works out. Hope that helps.
