Is there any troobleshooting tips for a 1999 4dr chevrolet blazer 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.

Your first problem is that somebody sold you the wrong fuel pump. The fuel pump that is supposed to work in your 1998 Chevrolet Blazer is available only as a complete fuel pump module assembly. The "pump only" kits are for the "old school" systems (cica 1980s / early 1990s) that run on much lower pressure and will not work with your vehicle.

Unless there is an access panel inside the vehicle above the fuel pump, you will have to remove the fuel tank in order to access the pump. Do not forget to replace the fuel filter. Partially clogged fuel filter is one of the causes of a failed fuel pump.

replace the fuel pump electrical wire harness.
