how to test the full pump
I assume you are asking how to check the fuel pump rather the a "full pump?" Your subject is "no injection," does that mean your injectors are not working, or that there is just no fuel making it to the cylinders? If you suspect no fuel to the cylinders, how have you come to that conclusion?
To get any reasonable help here, you're going to need to provide more details. Many of us on the this forum could write several pages on why your car may not be starting. Probably none of us have time to do that.
Please post a follow up with the year of your Taurus/Sable, which engine it has, and what the symptoms are, and what you've checked.
If all you really want to do is check to see if the fuel pump is working, then you will need a test light or multimeter and a fuel pressure guage. Attach the fuel pressure guage to the fuel rail and turn the key to the run position. If there is no fuel pressure, you may want to replace the fuel filter to make sure it's not just completely clogged. Fuel filters should be replaced regularly anyway. Check the pressure again. If you still don't have fuel pressure, then check for voltage at the fuel pressure inertia switch. If you have voltage there, then you most likely have a faulty fuel pump or wiring to the pump.
