Oil Furnace does not always light

Starting last weekend the red reset switch inside the furance has tripped several times when the furnace was starting. The blower continues to run, but the furnace does not light. If I shut down the blower, press the reset switch and then bleed a little oil out at the pump while the furnace is attempting to restart the furnace will light. There is a puff of gray smoke though when the furnace lights. I'm at a lost and looking for any help troubleshooting.

It could be any number of things but I'd start by replacing the filter cartridge, pump screen, & nozzle. Before installing the new nozzle, flush at least 15 seconds worth of oil thru the system, THEN install the new nozzle. Clean the electrodes & make sure they are set to manufacturer's specs. If this doesn't take care of the problem the igniton transformer could be weak.
