Are you positive you are getting fuel pressure? Also are you certain that plugs wires are in correct order?

Check the circuits related to the ignition being in the "run" position. Does the radio work, along with other systems which usually operate when the vehicle is operating normally? If no, suspect a problem with the ignition switch/module. In the run position, you should be getting power to the coil
