Edited text with a wild guess at the maker. Make model (what it is) in all questions please.
Category moved to John Deere Tractor.

If it was working before, there is no need to worry about the firing order as that never changes. Things to look at;
Clean and correctly gapped spark plugs,
Clean gas,
Fuel filter?
and a clean carburetor, float bowl and jets.

30 weight non detergent works in most pressure washer pumps. available at most auto parts stores.

junk axial wobble plate pump. Usually axial pumps are not worth the time to try to fix them. This one has a 5 year warranty , so they think they have a pretty good one. ( I would never buy one) If you want to try to fix it, I would check the check valves first. Take them out and see if some are broken or not sealing properly. There is a valve kit available.
The other likely problem is your unloader valve. If the seal is shot or the valve stuck open the pump will not build pressure.

check your check valves.
or one of the wobble plate pistons is not working right ( broken, broken spring etc)

np3020 E-500

this is a piston seal issue. You can get a kit to rebuild the pump.

You should use what the pump manufacturer recommends. Typically a 30wt non-detergent (non foaming) oil. Do not over fill. If there is a sight glass half way is normal. Or if it has a dip stick follow the mark there.
