motor runs, fuel is primed motor it wired in parallel with ignitor and controled by this http://www.grainger.com/Grainger/ww...ch&Ntt=4e291&N=0&GlobalSearch=true&sst=subset

i have check the flame sensor and have ~100ohm acrossed it when off. with the furnace on there is 40-50 mV across the poles.
the sensor is relatively cheap.. but i dont know what is good or bad..

is the igniter working? is it spraying fuel correctly? does it light for a minute and then shut itself off? I've never messed with a fuel oil burner so im just guessing here....

Replace Filter and nozzle. Is it a Beckett burner? I service so many of these in the winter for same reason. A little bit of dirt gets in tip and ruins spray pattern and it will not fire.

Like vrabel said, if I were showing up on a job that the tank were run dry, the first two things I would do is replace the nozzle and filter. If you still had issues I would check the "igniter pack" on top of the burner. Hope you get it working.
