Depends what kind of pump. -If a submersible pump, the AMP test is good. If amps are within 'service factor' and pressure is still low, you have a bad 'wet end' or a leak somewhere. - If a jet pump, it may be cavitating, have a blocked nozzle, or have a warped impeller.
To adjust the pressure switch on your water pump for optimal performance and efficiency, locate the switch on the pump and use a screwdriver to adjust the pressure setting. Increase the pressure if the pump is not turning on or off at the desired levels, and decrease the pressure if the pump is cycling too frequently. Test the pump after each adjustment to ensure it is working properly.
To adjust the well pump pressure switch for proper water pressure, locate the switch on the pump and use a screwdriver to adjust the pressure settings. Increase the pressure by turning the screw clockwise and decrease it by turning it counterclockwise. Test the water pressure after each adjustment until it reaches the desired level.
Fuel pump pressure test.
To install a water pump with a pressure tank, follow these steps: Choose a suitable location for the pump and tank near the water source. Connect the pump to the water source using appropriate piping. Install a check valve to prevent backflow. Connect the pressure tank to the pump using a pressure switch and pressure gauge. Adjust the pressure settings on the pressure switch according to your needs. Test the system to ensure proper functioning. It is recommended to consult a professional if you are unsure about any step in the installation process.
you would need a tool which is called a pressure tester, if you see a leak from the water pump during the test then your water pump is bad and need to be replaced a.s.a.p
there should be a pressure gauge on a pipe leaveing the pump, or if it dumps into a catch pan then watch the flow,
Start with a fuel pump pressure test.

you will need to hook a pressure gauge up to the fuel rail. If the correct pressure is not obtained then the pump is bad. If too much pressure then your fuel pressure regultor is not working. You will need to find out what the normal operating PSI range is for this pump first.
Typically the water pump will make noise or show residue from leaks from the water pump bracket. You could also use a special tool that puts about 10-14psi of pressure on the cooling system and raise the car and see if it leaks from the water pump.
To adjust the water pressure switch for optimal performance, locate the switch on the water pump and use a screwdriver to turn the adjustment nut clockwise to increase pressure or counterclockwise to decrease pressure. Test the water pressure after each adjustment to ensure it is at the desired level.
Run a fuel pressure test with a fuel pressure gauge connected to the fuel rail.
