On the 2.2L you need a special kit to install the gauge in the fuel delivery line with quick-disconnect fittings. There is no fuel pressure fitting on the rail to connect it.
You will have to get this kit and install it before you can check the fuel pressure. Your service manual should give you the part number for the kit.
