First thing to do when having electrical issues is make certain the battery connections are all absolutely clean, free of corrosion and tight. This includes the connection to the starter. Then have the battery and alternator tested. NEVER assume the items I previously mentioned are not the problem. If all is good proceed to the next step. You may require a mechanic's service to get it sorted out.

Found the problem.... A fuse was broke off inside the fuse box and couldn't see it easily.
