My grapple will not hold pressure when closed. They will slowly drop when opened and will not hold on to anything I try to pick up. I changed the female coupler on the machine but it made no difference. Should I try the male side next?

The couplers will have nothing top do with it unless they are visibly leaking.
Your issue is either in the spool valve or more likely you have a blown internal seal on the cylinder.
If it has more than one cylinder you will have to isolate each cylinder to find out which one is causing the issue.
