Depending on how long the engine was ran with diesel …
There possibility may be engine damage.
I would suggest R&R the spark plugs and perform both a compression and leak down test on all cylinders.

Did you test them to factory specs? of just going by visibly seeing fuel spray.
Did you test and confirm the fuel pump is within factory specs?
