I have been using diesel in the old oil furnace until the gas one gets installed it runs out a lot so I prime the pump and pushed the red reset button (was told how to do that in this forum) the motor starts running then goes off a few times, eventually oil starts coming out of the loosened nipple under the fuel pump and then the burner kicks in and I tighten the nipple. This time when hit the red button nothing happens no pump just silence. Also the reset stays down untill i pull this small plastic leaver just above it. I have no idea what to do next.<br /><br />Thank you<br />Rob
