After much internet research I found what was causing my truck
à   to start then shut off. It is the pass lock 2 security on my truck. My truck has pass lock 2 built in the ignition switch, when I went to start it, the ignition switch was telling the BCM that it was not the right key, which in turn cuts off the fuel to the injectors. After 10 min it resets itself. I found out 3 different fixes for this problem, 1. Buy a 70.00 module to fix it. 2. Find the wires and put a toggle switch on 1 of the wires (if you forget to flip the switch after starting, it records codes in the computer) 3. (The method I used) take the cover off the steering column, find the wires coming out of the switch, should be 3 wires 1. Yellow, 2. Red/white 3. Orange/black. You cut the yellow wire into (leave enough wire to work with)the yellow wire coming out of the switch will no longer be used so tape it up, then strip some insulation off the orange/black wire (do not cut into)take a ohm meter and turn the switch on. Do not start. Check the resistance between the orange/black & yellow wire going away from switch. When you get the ohm reading, find a resistor (Radio Shack) somewhere over the value that the meter read. Now solder this in temporary between the orange/black & yellow wire going toward the BCM. Try to start, if it doesn't start wait 10 min then try again. Sometimes you may have to go with a bigger size resistor but I promise this works because it fixed my truck
