How to check the fuel pump output and pressure on Cadillac Seville?

On a Cadillac Seville, first check that the fuel tank has enough fuel. Then let out the current fuel pressure before you can measure the pump's output. Hook a fuel pressure gauge to either the fuel line or fuel rail, only using one that has a bleeder valve and works with the fitting type needed for the vehicle. Turn the ignition key to "ON" without starting the engine. Watch how long it takes the fuel pump to run, and make sure the gauge's readings stay within the correct specifications. While running the engine, the fuel pressure should go down by 3 to 10 psi. Also add vacuum to the pressure regulator, check that it works correctly. If you see higher than allowed pressure, make sure the regulator gets vacuum, then look for restricted flow in the return line. Replace the fuel filter if low pressure readings appear. Then test multiple fuel system components with a special valve. After the tests, reduce the fuel pressure and disconnect the gauge. Have the person in charge turn the ignition to ON, and check if you can hear the fuel pump wind up its noises from under the hood when someone else loosens the fuel cap and sits nearby to listen. Under the passenger seat cushion of 1999 and later models, you'll find the fuel pump fuse that needs checking before you can continue. First check the fuel pump fuse is good; if it is, disconnect the relay and measure battery voltage at its connector under both OFF and ON ignition key positions. When the pump isn't working, ensure the fuel pump has battery power at its connector. If the battery current isn't there, look for problems in the electrical circuit between the battery and pump. When the pump isn't working with power, join the pump directly to the circuit to see if it runs. Finally, test your oil pressure switch when the fuel pump won't run, after making sure all electrical circuits are working well.
