how do i check the fuel pressure

Fuel Pressure should be 38 to 44 psi with the engine running. You need to tee in a fuel pressure gauge into the fuel rail. It is probably safer and cheaper to have a professional repair shop check the pressure than buy tools you may only use once. Autozone have some popular workshop manuals for free on line once you register (for free) on their website http://bit.ly/autozone_repair_info. and get an online repair manual subscription. There is a company that independent auto repair shops "buy" their information from that the same information inexpensively to do it yourselfers. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect....
