p1209, p1211,p1212, p1247, and p1248. can you tell me what that means or where to find out.

you should probably check your fuel pressure between the pump and the fuel bowl. my bet is that is is dropping pressure to zero causeing it to shut off just after it gets running. and there are several things that could cause that but the first to check is a return line valve on the side of the fuel bowl. that when pressure builds up it releases back into the tank and if it gets stuck open you will not have enough fuel pressure to run your truck. mine just did the same thing.

Release the throttle when fuel cut-off occurs.
Observe the fuel cut-off specifications for the applicable engine.
The engine should not accelerate beyond the calibrated RPM value.
Release the throttle immediately if the value is exceeded.
Block the drive wheels.
Set the parking brake.
DO NOT apply the brake pedal.
Cycle the ignition from OFF to ON.
Apply and hold the brake pedal.
Start and idle the engine.
Turn the A/C OFF.
The vehicle must remain in Park or Neutral.
The scan tool monitors certain component signals to determine if all the conditions are met to continue with the procedure. The scan tool only displays the condition that inhibits the procedure. The scan tool monitors the following components:
Crankshaft position (CKP) sensors activity--If there is a CKP sensor condition, refer to the applicable DTC.
Camshaft position (CMP) signal activity--If there is a CMP signal condition, refer to the applicable DTC.
Engine coolant temperature (ECT)--If the engine coolant temperature is not warm enough, idle the engine until the engine coolant temperature reaches the correct temperature.
