Engine Mechanical problem
2002 Chevy Avalanche V8 Two Wheel Drive Automatic 120, 00 miles
Truck stopped was very low on fuel but I think had enough. Now with tank filled won't start without strting fluid and runs for 3 seconds and stops. You can keep it running rough if you keep squirting starting fluid. I replaced fuel filter opened fuel pressure valve near fuel rail and turn key on & off several times only a drop or 2 no pressure or flow. Also swappped horn relay with fuel pump relay to & wasn't that.
Can it be anything else besides fuel pump in tank?
