Yes, this can be the problem, here I have included some firing order diagrams so you can double check.

Please let me know if you need anything else.

Do you have a repair manual if so-Put the engine no.1 piston on its compression stroke/TDC, align the cam and crank sprockets to their markings, put crank pulley on TDC/0 deg and rotor pointing to no.1 cap tower.
