vehicle acted as if out of fuel. added fuel no help as battery died attempting restart. engine will crank a couple times them battery dies flat again, feared fuel pump, or alternator. Starter function. thought a relay might be the source? if battery is discharging like this would that also explain why it acted like it was out of fuel? Battery inspect after second discharge I found one very dry cell, filled it and recharging. If this fails I wanted to check these relays and there sockets as next diagnostic.
