Why does my fuel pump quit working on my dirt bike?
Mechanic’s Note: When a bike sits for too long the capacitor bleeds off power and can make the bike hard to start. Sometimes fuel pumps just quit. Tired of life or at least running you around. The quitting fuel pump results from a number of reasons, age being one of them.
What should I do if my bicycle pump is not working?
Put the nozzle back on the tire using the other hole. Remove the nozzle if air will still not go into the tire. Inside the nozzle there’s a small core. On some pumps this core is reversible. Pull the core out with your fingers, spin it around and put it in backwards. Place the nozzle back on the tire valve and pump the handle.
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. Newer EFI bikes feature a check engine light on the kill switch that blinks a code indicating the problem but a bad fuel pump might just need a new filter. Today’s technology doesn’t always offer an immediate and exact solution.
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.

Bicycle pumps take a real beating. You force them, push on them, knock them around and take them everywhere with you on your bike, collecting all kinds of dirt and crud. It’s a wonder they work at all. Several reoccurring problems with bike pumps are usually simple to fix, and other problems that will require you to get a new pump.

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.
