Have you done a fuel pressure test? If so what psi is key on engine off? If you havent doen a fuel pressure test thats what you need to do. If its low replace the filter and check again if still low verify the pump ha good power/ground and replace. Let me know if you have questions, thanks.
Ok, then your fuel injectors arent firing. Try to swap the main relay with another one to see if that helps. Check to see if the relay clicks if not check for good ground and good power. If no power check 15 amp engine fuse. If the relay does click then check to see if the 30 amp EGI fuse is good and the 40 amp IC key fuse. Here is a wire diagram of the injector system, let me know if you have questions. Thanks.
