91 D21 CRANKS BUT WON'T START.

1991 Nissan Truck • 4 cylinder 2WD Manual •

I have a 1991 Nissan D21, it has some kind of wiring short somewhere, the main relay does not click, therefore no spark no fuel pump. The relay is fine, i've tested it and also put one in from a working truck. The ECM is also fine and works in another truck. There seems to be power on the black and white wire coming from the relay even when the relay is removed, and I don't think there should be. I need detailed wiring diagrams. Any Help would be sooo much appreciated.
