You already have the idea but that does not solve the problem. You need to perform testing to find out which of these is the cause.

Definitely not fuel pump because it would affect all cylinders.
Were the spark plugs checked?

Misfiring can be due to various causes, spark plugs, wires, distributor cap, EGR, injector, engine compression.
