I need help with yet another fuel pump problem. My primary pump failed and I replaced it. The car started and ran fine a few times over a few days and then wouldn't start again. Instead of starting up instantly it cranked for two or three seconds so I suspected that the secondary pump was no longer running. By way of troubleshooting, I used an outside battery to power the secondary pump and it runs fine. I reconnected the connectors and ran power to the external connector on top of the filter housing and again the pump ran fine. By following several threads I checked all the fuses in the car and they were all good. I found the 404 relay and removed it to check power to the number four terminal and it has power to it. I swapped this number 404 relay with another one and that didn't help. When I opened the driver's door I cannot hear the pump come on. The convenience light comes on when I opened the driver's door and I hear the door chime. To me this indicates two potential problem areas: a break in the wire between the number 404 relay and the fuel pump, which I doubt, although there is no power transmitted to the connector at the fuel pump. The other possibility is that the switch or switches that activate the number 404 relay are not sending a close signal to the relay. I am to the point of running new wires from the secondary pump to a toggle switch on the dashboard. HELP! Thanks, Fred.
