1. Attempt to start the truck by turning the key to the Start/Run position. The passlock icon may be illuminated or flashing. Try to crank the vehicle.
2. Release key to the ON/RUN position (not the ACC position or OFF)
3. Allow the vehicle to sit with key in the ON/RUN position until the passlock security icon turns off. This could take as long as 12 minutes
4. When the light goes off, turn key to OFF position and keep the key in the OFF position for no less than 30 seconds.
5. Go to #1 and repeat for four cycles or until vehicle starts.
You talking about the seat icon? Which light is flashing? If you do not connect seat belt that light will not go out. If you have a dog the seat belt light will flash if it is on front passenger seat. Which icon light is flashing?
After connecting battery, try using key in drivers door to lock, and /or unlock. Try passenger if that doesn't work, as well as valet key if it came with one.
The key cylinder sensor may be faulty. if you would like to bypass the system (works only if Passlock security module is ok) follow the link. How To Permanently Disable GM PassLock System
A fast flash usually indicates a burned out bulb. If you no flash in the rear, that is probably the culprit. Keep in mind just because your taillight works doesn't mean your flasher will. Most newer cars have combination bulbs in the rear with more than one filament in them. Try cahnging the bulb in the rear and if this doesn't help, reply back and we can explore this further.
Start with simply changing filter and fluid for transmission. If that doesn,t work go to your local parts place and scan the codes on your vehicle. I have the same problem and that is what I am doing.
Do you have any check engine lights on? Is your anti-theft light flashing? If so, put key in igniton, turn to on (NOT START) leave in on position for EXACTLY 10 MINUTES As SOON as theft light turns off, try to start.
