If you crack open a fuel line and have sufficient fuel delivery and volume but do not have fuel arriving to the throttle body or fuel rail there has to be a restriction in the fuel line. If fuel is arriving at the fuel rail it requires the fuel injectors getting power and the power train computer getting inputs from the engine's many sensors the computer processes these signals and calculates when and how long to ground or switch on the injectors for. Autozone have some popular workshop manuals for free on line once you register (for free) on their website http://bit.ly/autozone_repair_info or there is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subscription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual try http://bit.ly/mitchell_repair_manuals_online
