The gasoline Club Car Onward 6 Passenger golf cart uses Kohler ECH440 EFI, so fuel-pump diagnosis should begin with pump voltage, ground and measured fuel pressure. Check the exact model-year pressure specification before replacing the pump.
Onward 6 Passenger • Symptoms + testing
Onward 6 Passenger fuel pump quick diagnosis
No-start first
Start with voltage, ground and actual fuel pressure. Pump noise alone is not enough.
No pump prime
Check the fuse, relay/control circuit and pump connector before replacing the pump.
Power loss
Low pressure under load can come from a weak pump, voltage drop or a restricted strainer/filter.
Pressure clue
EFI pressure — verify exact service spec
Onward 6 Passenger bad fuel pump symptoms
Cranks but will not start
Check pump power and ground first, then measure actual fuel pressure. A pump can run audibly and still be too weak.
Starts then dies
Watch fuel pressure and pump voltage as the engine dies; a weak pump, voltage drop or restricted strainer can cause pressure to collapse.
Weak under load
Low pressure often appears first during acceleration or climbing, when fuel demand is highest.
No pump prime
Check the applicable fuse, relay/control circuit, connector voltage and ground before condemning the pump.
Pump runs but pressure is low
Inspect the filter/strainer, pickup and line for restriction, then compare pressure with the exact service specification.
Intermittent operation
Check connector tension, corrosion, ground integrity and relay/control output while the fault is present.

Club Car Onward 6 Passenger fuel pump FAQ
What fuel-pump system does the Club Car Onward 6 Passenger use?
The gasoline Club Car Onward 6 Passenger golf cart uses Kohler ECH440 EFI with kohler ech440 efi. That means the most useful checks are pump voltage, ground and measured fuel pressure.
What are the most common Club Car Onward 6 Passenger fuel-pump symptoms?
The usual signs are long cranking, no-start, starts-then-dies behavior, hesitation and loss of power caused by low EFI fuel pressure on the Onward 6 Passenger.
How do I test the Club Car Onward 6 Passenger fuel pump properly?
Start by checking the applicable fuse or control circuit, then verify pump voltage and ground during prime or cranking. After that, measure actual fuel pressure rather than judging the pump only by whether it makes noise.
What fuel pressure should the Club Car Onward 6 Passenger have?
For this page, the pressure guidance is EFI pressure — verify exact service spec. The gasoline version is documented with Club Car's Kohler ECH440 EFI powertrain. Use the exact model-year service manual for the numerical pressure target and electrical test points.
Why can the Club Car Onward 6 Passenger fuel pump run but still be bad?
Because an electric pump on the Onward 6 Passenger can still spin and make noise while failing to maintain enough pressure under cranking or load. A restricted strainer/filter or voltage drop can create the same symptom, so pressure testing matters.
What should I rule out before replacing the Club Car Onward 6 Passenger fuel pump?
Rule out low voltage, poor ground, fuse/control problems, connector issues, restricted filter/strainer, a kinked fuel line and incorrect pressure testing before replacing the pump.
Fuel-system design, wiring, pressure specifications and replacement parts can vary by model year, engine and configuration. Before testing or ordering parts, confirm the details in the official owner, operator, parts or service manual for your exact Club Car Onward 6 Passenger and serial range.
