Info:
1997 Blazer 4.3 4D 4WD

Issue:
Lights left on for a few hours, but car still started and drove a mile.
Car died on highway causing battery light, check gauges light.
Car cranks but no start.
Tried jumping.
Replaced battery. (still low voltage but no luck)
Car does start when fuel is splashed into intake, then dies.
Replaced fuel pump and filter.
After I replaced the pump, there is a sputtering noise above the engine. Likely fuel. But it never made the noise prior.
Still no luck, and at this point without some help I will have to tow it to the chevy dealer
