Car would sporadically crank but not start. After having already changed the fuel pump I figured the relay was the only other thing it could be.

Tools/ supplies/ parts used: flat head screwdriver, phillips screwdriver, pick tool, needle nose pliers, 10mm socket, 1/4 ratchet, flashlight (depending on your lighting situation), and the relay Duralast part# 20113
