It is a fuel pump code, it means the computer is not getting a signal back from the fuel pump and the pump may be burnt.
Check the fuel pump relay for correct operation, if it is functioning then check the ground circuit. If you have vary high resistance, or no resistance then the pump is burnt and you need to replace the fuel pump.
If your 1995 Chevrolet Blazer shows code P19DA, it means that there is a signal problem between the fuel pump and the PCM. This may have happened because you have a burned fuel pump motor, or the float meter of the fuel pump has a burnt wire.
Check the fuel pump relay, if malfunctioning, inspect the ground circuit to and see if the resistance is accurate. If it appears to be damaged, remove the fuel tank, taking out the pump, and replacing it with one that works.
