You can purchase a fuel pressure tester or alot of chain auto parts stores have them for rent. You will connect it to the schrader valve as in the pic above. Unscrew the black cap and install the tester.
You can then use that red wire I mentioned. That is just a jumper wire directly to the pump. That wire is used for testing and diagnostics, which you are doing. It will run the pump even if the key is off. When applying current to the pump, the gauge should read about 40-45psi. It should jump up almost instantly. If it takes more than 2 seconds, the pump is weak, it it doesn't reach at least 35psi, the pump is weak or shot.
If it is an ACD, it has a LTW.
