Wont start

Hi There are a number of things that will exibit the symptoms you are experiencing first I would start with the easy items like security, take the #1 key if possible place it in the door and unlock and lock the door several times holding it in the lock and unlock position if the vehicle is equipped with security factory and aftermarket, The likely causes for these symptoms are 1- blown starter fuse and or relay. 2 - vehilce is in security mode procedure mentioned above 3- Faulty ignition switch (common problem) 4- Connection issues for exasmple at the battery or ground., 5- PCM / ECM Thee list is ongoing but I would start with the simple like fuses,
