2003 Mercury 4 stroke 4 cyl efi. Boat ran last year. I took the deck off and flipped it so I could recarpet it. Yesterday it fire but elec fuel pump had no juice to it. I went through the 3 relays on the back and checked them all. Hot wire the fuel pump to see it it work and you could hear it pump. Checked all the fuses, the throttle control safety switch and now no spark or fuel pump. Mech fuel pump is pumping

That was my thought for sure. About the wire getting unhooked. I should have started it prior to starting disassembly just to make sure it was good but I didnt and it sat for the winter. I have looked and looked and cannot find any wires unhooked. I guess I need to know what the source is to for the fun pump. Does the ignition send a juice to one of those relays? And if so which one? Also what is the other source of the relay if so? Is that also the key?
