I recently picked up a 99 ram single cab with a 5.9 auto. I've always wanted a 24v standard cab truck. I managed to pick this truck up cheap with a smashed front end. It started up and moved so I knew I had to get it. Got it home and over the past couple weeks i've managed to aquire a complete radiator support and parts to put the front end back together. Today I went to start it up and hook the RF frame to a tree to straighten it and the truck started then cut off after about 5 seconds. Long story short no fuel. The truck has a FASS system under the bed right behind the driver seat and the filters were empty. I found the power and ground harness to the relay for the system not hooked up. Connected them but still no go. So i put 12v directly to the supply to the pump and it'll make noise like it's pumping but no fuel. I removed the water separator and filter and it's not pumping at all. There's a serial number but no part numbers on it but I assume it's a 165gpm since that's what most sites sell for these trucks. Should I pull the bed and check tank to make sure something hasn't come off inside and it's just sucking air or is it time for a new pump motor? I can't seem to find a 165 fass replacement pump
