Old Lennox oil furnace model # starting with OH. The label is damaged so I can't see the rest of the model #. It has oil just will not ignite. Help

To start, I would suggest a basic tune up: Replace the nozzle, fuel filter, & pump screen (if applicable), & clean & adjust the electrodes. If that fails to get you heat, post back & we will delve deeper.
