Furnace blowing cold air

I have a Beckett furnace and I ran out of fuel, I filled the tank and the furnace comes on but it only blows cold air and the red light is flashing indicating a soft lockout, what should I do to get it running again

Is this an oil or propane furnace? If yes, I think there's a button on the control you can push to reset it.

Only push it once, then call a tech.

If you only have one fuel line going to the pump, the pump is full of air & must be bled. To do so, you will need a 3/8" wrench, a hose (even a drinking straw will work), & a container to catch the oil. Put the hose over the brake bleeder valve sticking out of the pump at the bottom right, push the reset, hold the hose into the container, & quickly open the bleeder about 1/3 to 1/2 turn with the wrench. When you get a full flow of oil or the burner kicks off, shut the bleeder.
