The code you are talking about is not likely to keep the truck from starting. Is the truck turning over , getting fire to the plugs, fuel to the throttle body and injectors. P0135- Oxy Sensor Heater Circ (bank1, Sensor. Does the fuel pump run and is the fuel filter clear and not blocked. Can you spray fuel into the throttle body and get it to start.

Sounds like the immobilizer system is preventing you starting it. This usually requires a main dealer to fix.

If you lay on your back on the drivers side floor and look at the brake pedal arm you should be able to see the brake light switch. You shouldn't have to remove anything to access it.

Hi Barbara, Im AL the owner of Big As Auto Repair

Barbara, it sound like you may have an actuator motor that is shorted, here how to check it. On the front axle you will see a motor assembly with wiring and connector. Unplug that connector and leave it off, then try to put it into 4 wheel drive. If it doesn't blow the fuse then you know its a shorted actuator motor. Hope this helps and please visit my auto-repair-website here: http://www.bigasautorepair.com/

your anti theft device is activated,you need to lock and unlock your doors a couple times with the key fob,not the key,and then you need to put the key in the ignition and start it,if you dont have your key fob,call your car dealer to get a new one,they are programmed for each car only,you cannot bypass it.
