Hi robertk46,

Check the fuel pressure. Thoug pump is working, the pressure could be insufficient.

Check the injectors. Unplug the injector and test for battry voltage with ignition switch turned on. At least one terminal must be hot. Attach a noid light and crank engine. Note if the noid light pulses.

Perform cylinder compression test. Note if they are within specs.

Misfiring codes could be due the fuel pressure, sparkplugs, compression loss or ignition coil.
