I have a 93 GT with fuel pump relay under hood near Maf. I hid my wires under the fenders, which meant I moved the relays there too. I drove it in one heck of a rain storm, parked it at my sister's house and came outside to find the pump running non stop. Finally stopped, made another trip in rain, same thing. Ended up frying the relay.
The relay connection pack is not weather proof and the bottom side was filling with water, which caused an electrical connection. I replaced the relay, after drying it out well, and moved everything further back in the fender...no more problems.
I recently purchased a weather pack relay off line for about $10 when I did my electric fans. Maybe a route to consider if your relays are getting wet, or take some other measure to protect them from water.
