electrical help

95 ranger xlt 4.0ok theres a fuse box under the hood with a smaller relay box that holds two relays coming out of the same jumble of wires that goes to the fuse box. im thinking its the abs relays. Anyways, when my truck is off these two relays buzz like crazy.. I can put either of the two relays on the left side of the box, and it wont buz, but if i put either in the right side of the box, it starts buzzing, and the truck wont run, it starts but wont keep running. im guessing its obvious somethings wrong with the wiring inside of htatl ittle box, like a prong is touching two wires... but the thing is.. when i put the relay in the left side and put the otehr relay BARELY in the right side, it wont buz, and the truck will start, but if i push the relay in all the way it will start buzzing and the truck will stop running. Any help?

thanks in advance,Kevin

anyone?

that sounds like the pcm or fuel pump relay and definalty sounds like a short in it somewere.

Have you tried just replacing the relay's?
The ABS wouldn't keep the truck from running, however if the relays are toast and or they share a common circuit,, there could be your gremlin, are the prongs black or discolored?
