Filter was complet mush and guk, also in the pump I took out and cleaned the screen , all good now, I primed filter and pump but still would not ignite. Blnk blk blk, after 3 second hold button furnace attempts then must hold for 30 secs to reset from lockout. SO after many attemps, "does it every time we run out oil" I took unit back out and took the long ( prong like things in front of were the oil comes out to lite. They were dirty, so I took them off and cleaned them, BUT, when I put thenm back on I'm not sure they are in the same position, also there's a small rubber like screw that I turned some. The furnace won't lite. Need to know how to set thos long prongs for lighting

Why did you clean the pump screen?
Just curious.

Do you have oil spraying in the combustion chamber?

Below measurements are text book. The next time you are going to do this get a electrode gap tool. They are cheap plastic but work well and takes all the guesswork out of using a ruler.

The distance from the nozzle tip out to the electrode tips should be 1/16"
The electrode gap (width between the two) should be 1/8"
The distance the electrode tips should be from center of nozzle is 7/16"

Also since you took the pump apart you should check for proper pump pressure. Normal setting is 100 PSI.
