According to an old Mitchel manual. There are 2 signs that the water pump has gone out. First, check the "weep" hole for seepage. The "weep" hole is located under the water pump so you'll have to get under the car to check it. The second is to listen for for a high pitch squeal. This can be confused with a belt squeal so be careful.
Another thing to think about, is that a water pump is designed to turn in the direction of the belt; that is,it turns WITH the belt. There should be some clockwise/counter clockwise movement; there SHOULD NOT be any movement in ANY other direction. In other words,turning when the engine is running is good,but any movement when the engine IS NOT running,is NOT good. Also when the pump goes bad,you won't find a few drips under the car engine-you will usually find a small lake...usually but not always.
test your alternator or fuel pump
The fire pump churn test, is when an operator runs the fire pump without the flow of water
If that is throttle body fuel injection, there is no fuel pump test port. You have to fabricate with some fittings and tap into the fuel line at the fuel filter.
Put it into a bucketful of water, it should pump. Activate the trigger by hand if necessary.
Hydro test is pressured the water to the required test pressure by hydro pump and where as the Hydro static test will be fill up water to the required level at atmospheric pressure .
You can test your 1997 Oldsmobile 2.4 liter engine oil pressure sending unit with a diagnostic tester. The diagnostic tester is the most reliable way to make sure your sending unit is working properly.
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
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.
You might as well change the Thermostat because it is comparatively inexpensive, but test the water pump to see if it needs to be replaced.

Fuel pump pressure test.
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.
Test for fuel pump pressure at the back for the throttle body at the schrader valve. Your fuel pump may be going out. This is the #1 problem with these cars.
Use a digital multimeter and test it for resistance.
there should be a pressure gauge on a pipe leaveing the pump, or if it dumps into a catch pan then watch the flow,

Where is the fuel pump fuse and relay on 1994 BMW 525i and how can I test to see why my fuel pump won't work
No, unless it was hit by lightening. They will send out and engineer to pick up the pump after it has been pulled. They will then test it and give you an answer.. $1200 for pump and $500 for labor is what I was quoted. 3-18-2012
If you are checking for it leaking, you will need to see it.
A Well Test Flow Report is a report giving the results of a test on a water well. The test is one designed to see how rapidly water can be removed from the well without (temporarily) drying the well by getting ahead of the rate at which it naturally replenishes itself. A report of this sort tells you how rapidly you can pump water fro the well on an extended basis.
