Default I don't have a fuel pressure gauge, is there a way to check problem fuel pump without

My 97 sl1 makes no noise out of fuel pump when key turned on. If I put new fuel pump relay in and same problem, fuse not blown, how do I use multimeter to check wires at fuel pump (please include settings on multimeter and what I connect + and - multimeter probes to)?
Also, can I just remove the fuel line somewhere to see if fuel come out with key on to verify faulty fuel pump (really do not want to buy gauge, very broke here)?
Thanks for any advice!!!

You can disconnect line down at the filter inlet. Catch fuel in bucket.

So if I turn key on and disconnect line at filter and fuel squirts out not a problem with fuel pump?

Disconnect the line first as the pump only runs for 2 seconds.

Read the comments for the videos also. Is there any other electrical thing that is not working in the car? Dome lamp, radio loosing memory, Chime?

If I pull the hose at the fuel filter and turn the key to the start position, if fuel sqirts out the hose, this means the fuel pump is ok right?? Thanks for the links by Richpin they were great!

Yes, And if it does not it just means that the pump is not pumping because it has no power or is broke.
