950 fuel pump not getting supply from ECU

Hi guys, I am new to your forum, but need your advice. Gave the 950 a proper lube service checked valve clearances, replaced plugs and did waterpump overhaul. While at it I replaced the OEM fuel pump with a facet, but once assembled, fuel pump would not run. Checked wiring between pump and relay and all seems fine. Unplugged and tested relay, also fine.
There are 4 wires on the relay, a positive and negative going to the pump, a 12v supply from the fuse box and the control wire from the ECU. Power on this wire presumably will let the relay click, causing the pump to run and that seems to be the problem -no supply on that wire from the ECU. What can be the cause? At no point did anything short and the bike ran perfect before I started working. Help please.
