Cranks for about 4-5 seconds then starts. after the first start it fires right up.
Already replaced fuel pump, fuel filter, and and TBI injectors. What else could

First, check the spark to see what it looks like, it should be white in color, not a orange color. Next check the fuel pressure. It may be the spring if the fuel regulator is weak, and so you may need a TBI rebuild kit, or if you can find a regulator kit, I think I've seen those.
