The fusible link is listed as "N" blue, located at the starter solenoid connections on the passenger side fender area of the engine bay. I would start first by checking for power at the red wire of the fuel injectors. If there is no power, then check the fusible links, a slight pull on the link can usually decipher whether it is good or not. If it pulls like stretch arm strong=bad. If you do have power at the red wire, then follow the illustration that I provided. You can either use a test light or a volt meter. If there is no flash either, then we'll have to have a look at the powers and grounds of the powertrain control module because if you have spark then you should have injector pulse, they both get the signal from the same place because the injectors fire four at a time.
