UL 350 fuel pumps

[mcnabb]

I'm hooking up the fuel pumps to the green shrunk wire from the new red ECU. I have the white wire and the white blue wire, the white wire has 12v. I have a switch that I can chose which pump to come on, the switch is pump one or pump two.i can't turn both of them on at the same time. Should the pump turn of after 15 seconds if the propeller isn't turnig and the master is on? The pump chosen stays on.

Hi there check if you have selected the main pump as that will switch off the secondary pump will run when the switch is on.
