First check your fuse. Then figure out the layout of the pins on your relay. Two of them are for the coil and the other two are for the switch. There should be a diagram on the relay or there will be pin numbers. 85 and 86 are for the coil, 30 and 87 for the switch. In the latter case 30 is always hot ( you can test with a volt meter ). Disconnect your battery ground and figure out where the corresponding slots on the mount are for each pin. Use a jumper to connect the slots for the switch (30 and 87). Reconnect your battery ground and go to your fuel tank, you should hear your fuel pump turn on. If not the pump is bad. If it does it's probably your relay. To test the relay you can put power ( with a 5 amp fuse ) to terminal 85 and ground to 86 ( the switch ) and the relay should click. With an ohm meter make sure there is continuity between 30 and 87 when the coil terminals have power and closed ( no continuity ) when the power is taken away from the switch.
Swap it with a known good one.
that means both the relay and fuel pump are accuratelly working.
Bad relay, No power to relay, Wiring from relay to pump and our most likely problem is, the fuel pump is bad. changed it already
A clicking fuel pump relay typically indicates that the relay is receiving power but may not be sending it to the fuel pump. This can be caused by a faulty relay, a problem with the fuel pump itself, or an issue with the wiring or connections. To troubleshoot, check for proper voltage at the relay and the fuel pump, and consider testing or replacing the relay and fuel pump if necessary. Additionally, inspect the fuse associated with the fuel system for any issues.
check fuel pump fuse..
relay is giving power to other relay pump not working
yes, the purpose of the relay is to signal the pump to turn on and off, if its not working at all the fuel pump will not turn on.
If the fuel pump relay switch is bad then the fuel pump will not be turned on. Think of the relay like a light switch. If the switch has a bad connection then the light doesnt work.
No, it shouldn't have anything to do with the starter. A bad fuel relay will stop the fuel pump from working.
To troubleshoot a non-working fuel pump in a Pontiac Sunbird, start by checking the fuel pump fuse and relay for any signs of damage or failure. Next, listen for a humming sound from the fuel tank when the ignition is turned on, which indicates the pump is operating. If there's no sound, test for power at the fuel pump connector using a multimeter; if there's power but the pump doesn’t activate, it may need replacement. Additionally, inspect the fuel lines for clogs and ensure the fuel filter isn't blocked, as these can impede fuel flow.
Yes, most definitely.
I doubt that it would be the fuel pump relay. If it's a throttle body injection vehicle, the injector could be stuck. But you wouldn't get ANY fuel into the engine if the fuel pump isn't working. Relay can be tested by turning key on but not starting. if you hear fuel pump 'HUMM', you know pump and relay are working. If no firing at keystart and experiencing flooding, not a fuel pump issue. There is a spark issue of some kind.
