Check ecm/bat fuse underhood first the red wire operates with the key to prime the pump. It sends power to the gray wire which goes to pump. After that the orange wire is hot after car is running. If not fuse is blown like the ecm /bat fuse then check to seeif power goes to orange wire. The other wires are tan which goes to ground on transmission stud so clean that and dk/green from pcm which commands pump on. You might see if your connections are good in fuse box and tweeking the prongs on relay to make sure it makes contact. Adding dielectric grease would help as well. It may be just a bad fuse box connection as well.
