When you turn the key you cant hear the fuel pump? turn off the radio and do not motor the starter and see? IF there is nothing and with the key on you go to the dizzy and move it then the fuel pump kicks on....you are likely looking at a bad TFI module/connection. check all of the wires on the module and wiggle them etc and see if one is pulled loose in the plug. if nothing hits the pump but moving it still makes the pump come on then it has to be the module. just because it was new doesnt always mean it is 100% good. thats where i would start

well for one stop throwing parts at it to try and make it start..that is not the proper way.....you need a wiring diagram of the fuel system and you need to have a test light handy so you can check for power back at the pump in the crank mode and briefly in the koeo mode for 2 sec...but there also is a reset switch for the fuel system/ inertia switch in the trunk behind the light panel..make sure it isn't tripped
