99 S10 4x4 no startfuel pump not running

Bought not running at auction. Removed pump and it runs with jump pack hooked to it out of tank. Key on,wire at tank gets current for a few seconds. Also shows current briefly when key is cycled off. Coil has
voltage,but not getting to plugs. Also,fuel gauge reads full with key on,then empty when cranking. Is there a factory security system?? Security light cycles on-off when key is on ,just once. Can this be a problem?? Can the computer be a problem??? Any help appreciated. 4.3 v6 automatic if this helps. Thanks Gi
