Check the standard errors if they show up. See if there are any really large ones. Also check the standardized estimates to see if they are consistent within factors, or if one has actually flipped signs (become negative). Watch my video about "iteration limit reached in amos". That should give you some more clues. I think I may have also shown some more troubleshooting in either my SEM Series CFA video or in my Boot Camp videos when I covered CMB.
