Remove a serpentine belt
There will be a spring loaded tensioner pulley keeping the belt tight. On the pulley arm, there should be a square hole that fits a 3/8" ratchet or pull bar. Put the pull bar in the hole and pull the pulley away from the belt to remove. Repeat to reinstall the belt. You might have to remove something to make this accessible.

Location of fuel pressure test valve
Not sure about what engine you have, but here is the general procedure.
Open the hood. Disconnect the negative battery cable from the battery.
Look on the front of the engine and find the fuel rail. The fuel pressure regulator is on the right side of the fuel rail. Follow the fuel lines toward the firewall until you come to a Schrader valve with a black cap. Rotate the cap counterclockwise and remove it from the valve.
Wrap a shop rag around a small flat-head screwdriver and press the center pin in the Schrader valve - you have relieved fuel pressure when no more fuel comes from the valve. Install the cap back onto the Schrader valve. Hope that helps.
