Just as the title says car won’t turn over in the cold but runs really strong and starts fine when it’s warm. Stuck seafoam in it to try and clean it out to no avail, help.

The easiest way to test the fuel pump is to spray starting fluid into the intake manifold. If this is a Vortec 350, you’ll have to spray it between the air filter and MAF sensor-- just get MAF-friendly starting fluid. If it starts, there you go.
Depending on how cold and warm you mean, it’s possible that you have a loose, corroded, or otherwise bad ground or battery cable. Warmer temp can expand metal bits just enough to connect, but shrink back up when cold. Sounds ridiculous but it happened to me in a 99 Suburban.
I should edit original post, it does crank, but just won’t start no matter how many cranks after it gets below about 25 degrees f
