Can a bad fuel pump cause an EFI bike to stop?

Diagnosing the problem often gives seasoned mechanics a headache. Injector problems can also mimic fuel pump problems.

How does a fuel pump work and how does it work?

At the top of the pump are two chambers. They are separated by a pair of one way valves. These valves ensure that the fuel that passes through does not come back. Fuel flows from one chamber to the other at one pulse and at the next pulse, fuel moves to the engine. A well maintained pump works at 5,000 pulses per minute.

How can I troubleshoot my air pump on my bike?

The same procedure for troubleshooting applies to both kinds. Place the nozzle at the end of the air hose on the bike’s tire valve. A lever at the side of the air hose nozzle locks the nozzle onto the valve. If the nozzle won’t fit on the valve, open or close the lever and try again.
