93 Ford Explorer No Power

My explorer will not start up at all , I changed the coil, battery and checked all viewable fuses... There is no power going into the truck no light s and will not even turn over at all , I checked the battery terminals and also starter wires , the battery is fully charged and when i TOUCHED THE COIL WITH A SCREW DRIVER ON THE COIL TERMINALS THE ALARM WILL KICK IN AND THE LIGHTS COME ON FOR A SEC...I was told to try this to see if there was any power .. Any suggestion will be great Thanks

Are you sure that the coil you put in is not faulty? Seems kind of strange that the alarm and light swent crazy when you touched it. Make sure the coil is wired correctly. Maybe a crossed wire or something? Also move around the battery wires and starter wired around. There could be a dead spot on one of the wires and it is not making good contact with the battery. Good Luck
