I have lost my owner's manual so I don't know what relays are what and I can't find a diagram for the relays so I know which ones are what or what fuses are what. Please help me. Thank you

I'm looking for the relays under the dash I found one relay that was bad fuel pump relay. I think it was a gray fuse.

I need to find the relay that runs the ignition coils because none of them are firing for spark plugs. There is something in the local system not letting the ignition coils fire and I don't know what it is.
