Oil Burner keeps tripping safety

I have an old Weil McClain oil burner and the fuel pump trips about twice a week. I had it serviced and its still the same. When I push in the pumps button then hit the transformer reset button it fires right up and doesnt burble too loud or have a fuel smell like it was loaded up with fuel which tells me its starving of fuel then trips. Im a novice so bear with me but could it be anything else besides the fuel pump itself? Anyway to test the pump? How hard are these to swap? I already put a new control box in it 2 years ago so I doubt its electrical.

I'm not the oil pro but it can be a number of things....

Partially clogged nozzle
Dirty fuel filter
Leak in fuel supply line allowing air in and vapor locking the pump (depends on tank location)
Intermittent high voltage transformer
Worn out/misaligned igniter electrodes
Dirty/defective flame sensor cell

Ours has tripped when chimney needs cleaning as soot will fall to back of unit and restrict proper air flow.

I pulled the motor to check it and it spins free and the pump seems good too.

If it was just serviced a week ago, I'd call the servicer back. The problem could be any of many things but chances are it's a simple adjustment or a tiny piece of junk has fouled the nozzle.

It was doing this before they worked on it so its not something they did.

If they were made aware of the problem, all the more reason to call them back. They should not charge for any additional labor.

I have an old Weil McClain oil burner
I worked with a guy who was better with languages than I am. He translated Weil McClain into English. It means "see you in 8 years".
