Check for power and ground at the pump assembly, if you have full power and grounds then the pump is bad. If no power check the fuel pump relay and wiring. If now activation power at relay check for blown fuses or relay actuator circuits

"No starting condition" generally is caused for 3 main malfunction reasons: 1.Power, 2.Fuel, and the 3. Compression...., If the engine is turning strong and (No starting condition) persist, and assuming engine cylinders compression and ignition unit/coil/spark Plug are good, Check fuel pressure at engine's fuel pressure port, Check fuel lines and filter for dirt/water, Check fuel pump fuse and relay, Check Fuel pump electrical connection for Voltage/Amperage at positive pin and for Ground/Resistance at NEG pin. fix and replace as needed. Thanks.

my pump is run off a toggle switch just have to remember to turn it off when you turn off the motor
