Bypass the starter relay and crank while the key is in the on position. This is to force the ecu to communicate. After doing that and making sure the check engine is on you can do the 30 minute key program procedure. Make sure the battery always stays above 12 volts

Thats bc the check engine light on keyturn illuminates as a self test... if it doesnt show up it usually means the computer isnt powered up
