"Good Auto-Electric Shop" Need to remove the Main Fuse/Relay Box, Check All the Wires and connections for Loose, Feared, Broken or Burnt. Replace the Relays (Bad By Now!). Check the Main Harness and Plugs at the Ignition Block/Module. Double Check the Battery, Have it Fully charged and then "Load Tested".
