Turn on the switch and nothing happens. That's frustrating right?  Here's a few things you can do to try to troubleshoot that. Before you start, check the pump model by checking the nameplate on the pump. Generally this located on the back of the motor or on top of the pump housing. - On select models, the safe stop time will activate after 30 minutes of running in bypass. Turn the pump off and allow it to cool down for 30 minutes before attempting to use again. - Check to see if the pump is receiving enough electrical power. Check for blown fuses or tripped circuit breakers. Power wires should be inspected for shorts or breaks (exercise caution when doing so), and should have a good connection to your battery. ***If you have an AC fuel pump, have a licensed electrician inspect power wiring.*** - If the switch still does not activate the motor, the switcher motor may need to be replaced. ***Use the links below to go to the walkthrough on how to do that with your pump type*** **EZ-8 Series** [Replace power switch](https://support.farmchem.com/knowledge-base/how-to-replace-the-power-switch-on-a-gpi-ez-8-fuel-transfer-pump?hsLang=en) **M-Series** [Replace power switch](https://support.farmchem.com/knowledge-base/how-to-replace-the-power-switch-on-a-gpi-m150-pump?hsLang=en) **V25 Series** [Replace power switch](https://support.farmchem.com/knowledge-base/how-to-replace-the-power-switch-on-a-gpro-v25-fuel-transfer-pump?hsLang=en) --- **Offerings covered by this post:** [GPI EZ-8 12V Fuel Transfer Pump, 3/4″ Manual Nozzle & 10′ Hose (8 GPM) – EZ-8 (Direct Mount)](https://farmchem.com/product/ez-8-12v-fuel-transfer-pump-3-4-manual-nozzle-10-hose-8-gpm-ez-8-direct-mount/) [GPI G20 12V Fuel Transfer Pump Only (20 GPM) – G20-012PO](https://farmchem.com/product/g20-12v-fuel-transfer-pump-only-20-gpm-g20-012po/) [GPI G20 12V Fuel Transfer Pump, 1″ Manual Nozzle, 14′ Hose & Spin Collar Mount (20 GPM) – G20-012MD](https://farmchem.com/product/g20-12v-fuel-transfer-pump-1-manual-nozzle-14-hose-spin-collar-mount-20-gpm-g20-012md/) [GPI G20 12V Fuel Transfer Pump, 1″ Auto Nozzle, 14′ Hose & Spin Collar Mount (20 GPM) – G20-012AD](https://farmchem.com/product/g20-12v-fuel-transfer-pump-1-auto-nozzle-14-hose-spin-collar-mount-20-gpm-g20-012ad/) [GPI M-150 12V Fuel Transfer Pump Only (15 GPM) – M150S-E-PO](https://farmchem.com/product/m-150-12v-fuel-transfer-pump-only-15-gpm-m150s-e-po/) [GPI M-150 12V Fuel Transfer Pump, 3/4″ Manual Nozzle & 10′ Hose (15 GPM) – M-150S-EM](https://farmchem.com/product/m-150-12v-fuel-transfer-pump-3-4-manual-nozzle-10-hose-15-gpm-m-150s-em/) [GPI M-150 12V Fuel Transfer Pump w/12″ hose, 3/4″ Manual Nozzle & Spin Collar Mount (15 GPM) – M-150S-MU](https://farmchem.com/product/m-150-12v-fuel-transfer-pump-w-12-hose-3-4-manual-nozzle-spin-collar-mount-15-gpm-m-150s-mu/) [GPI M-150 12V Fuel Transfer Pump, 3/4″ Auto Nozzle, 12′ Hose & Spin Collar Mount (15 GPM) – M-150S-AU](https://farmchem.com/product/m-150-12v-fuel-transfer-pump-3-4-auto-nozzle-12-hose-spin-collar-mount-15-gpm-m-150s-au/) [GPI 115V M-1115S-AU Fuel Transfer Pump, 3/4″ Manual Nozzle & Spin Collar Mount (12 GPM) – M-1115S-MU](https://farmchem.com/product/115v-m-1115s-au-fuel-transfer-pump-3-4-manual-nozzle-spin-collar-mount-12-gpm-m-1115s-mu/) [GPI 115V M-1115S-AU Fuel Transfer Pump, 3/4″ Auto Nozzle & Spin Collar Mount (12 GPM) – M-1115S-AU](https://farmchem.com/product/115v-m-1115s-au-fuel-transfer-pump-3-4-auto-nozzle-spin-collar-mount-12-gpm-m-1115s-au/) [GPI V25 12V Fuel Transfer Pump Only (25 GPM) – V25-012PO](https://farmchem.com/product/v25-12v-fuel-transfer-pump-only-25-gpm-v25-012po/) [GPI V25 12V Fuel Transfer Pump, 1″ Manual Nozzle, 18′ Hose & Tank Adapter Mount (25 GPM) – V25-012MD](https://farmchem.com/product/v25-12v-fuel-transfer-pump-1-manual-nozzle-18-hose-tank-adapter-mount-25-gpm-v25-012md/) [GPI V25 12V Fuel Transfer Pump, 1″ Auto Nozzle, 18′ Hose & Tank Adapter Mount (25 GPM) – V25-012AD](https://farmchem.com/product/v25-12v-fuel-transfer-pump-1-auto-nozzle-18-hose-tank-adapter-mount-25-gpm-v25-012ad/) [GPI PRO20 115V Fuel Transfer Pump, 1″ Manual Nozzle, 18′ Hose & Tank Adapter Mount (20 GPM) – PRO20-115MD](https://farmchem.com/product/pro20-115v-fuel-transfer-pump-1-manual-nozzle-18-hose-tank-adapter-mount-20-gpm-pro20-115md/) [GPI PRO20 115V Fuel Transfer Pump w/QM Meter (20 GPM) – PRO20-115PO/QM40G8N](https://farmchem.com/product/115v-fuel-transfer-pump-w-qm-meter-20-gpm-pro20-115po-qm40g8n/) [GPI PRO20 115V Fuel Transfer Pump w/QM Meter, 18′ Hose & 1″ Auto Nozzle (20 GPM) – PRO20-115AD/QM40G8N](https://farmchem.com/product/pro20-115ad-qm40g8n/) [GPI PRO20 115V Fuel Transfer Pump, 1″ Auto Nozzle, 18′ Hose & Tank Adapter Mount (20 GPM) – PRO20-115AD](https://farmchem.com/product/pro20-115v-fuel-transfer-pump-1-auto-nozzle-18-hose-tank-adapter-mount-20-gpm-pro20-115ad/) [GPI 115V/230V PRO35-115AD Fuel Transfer Pump, 1″ Auto Nozzle & 18′ Hose (35 GPM) – PRO35-115AD](https://farmchem.com/product/115v-230v-pro35-115ad-fuel-transfer-pump-1-auto-nozzle-18-hose-35-gpm-pro35-115ad/) [GPI 115V/230V PRO35-115 & QM40 Combo, No Nozzle (35 GPM) – PRO35-115PO/QM40G8N](https://farmchem.com/product/115v-230v-pro35-115-qm40-combo-no-nozzle-35-gpm-pro35-115po-qm40g8n/) [GPI 115V/230V PRO35-115 & QM40 Combo w/1″ Automatic Nozzle (35 GPM) – PRO35-115AD/QM40G8N](https://farmchem.com/product/115v-230v-pro35-115-qm40-combo-w-1-automatic-nozzle-35-gpm-pro35-115ad-qm40g8n/) -
