Check your Ignition Switch. here is an online manual site that will have the wiring diagrams, for a small fee, but well worth it.

re wire the fuel system, put a on/off switch connecting to the battery. basically its a bypass make sure when doing to turn the switch off everytime turning enigine off cause you will kill the battery if leaving on.
