BF225 Fuel Pump Has No Power: Causes and Solution

What’s the main cause behind the Honda BF225 fuel pump no power? The reason is probably a rusty or old fuel pump that has been unused for days. There can be other causes as well, such as bad fuel.

Fortunately, no matter what the cause is, there is also a cure. But, to get the fuel pump running again, you have to make sure to fix the device in the right way.

If you are confused about what to do now, this article is just for you. Here you will get to know what you can do when your BF225 fuel pump has no power. So, give this entire article a thorough read to get the understanding you are looking for.

5 Reasons Behind BF225 Fuel Pump No Power & Their Solutions

In The Hull Truth, someone questioned why their fuel pump wasn’t getting any power. In response to this, the account owner of Fwpratt said,

“So, sounds like you have ‘phase separated’ fuel due to a high amount of water contamination in E-10 fuel.”

Later he provided a solution to this problem as well. Fwpratt says,

“You need to disassemble the VST, examine and clean it, clean out the fuel rail and hoses. Likewise, the condition of the fuel injectors is in doubt – they should be removed, tested, cleaned.”

As you can see, it is recommended to check the entire fuel system when the fuel pump doesn’t get any power. But how do you do all these? This article will help you with just that.

But before getting into the main part, take a quick look at the reasons and solutions behind the BF225 fuel pump issue.

Clogged hoses and fuel railClear out the fuel rail and the hose

Now let’s get into the main topic.

Reason 1: Wrong Water to Fuel Ratio

The engine won’t get started without the proper fuel. It’s an essential element for the machine. In case the mixture somehow gets contaminated or ruined, it will affect the combustion of the engine, and make the whole fuel useless. As a result, the fuel pump won’t get any power as well.

Solution: Get Pure Fuel in The Tank

As the problem is with polluted fuel, you have to get the right gas into the system. All you got to do here is pour out all the old fuel from the fuel tank and wash the inside of the tank with fresh, clean water. Then wait for the tank to dry out.

After that, pour in a new batch of fuel and try to turn on the engine. If the fuel was the issue, the fuel pump of the outboard motor should get power now.

Reason 2: Blown-up Fuse

The fuse in your engine keeps all the components from having electrical issues. Not only the engine but the fuse also keeps all the wires, gauges, and other electronic components from being damaged.

If this fuse blows up, the whole engine will fail to start. The fuel pump, too, requires an electrical signal to function. So, the fuse blowing up will also mean it won’t get any power.

According to Honda Marine BF225 outboard manual, fuse #2(10A Fuel Pump), #4(15A ECM, Injector), and #7(15AECM, Injector) can be checked for no power issue.

Solution: Replace the Fuse

Replacing the blown fuse in BF225 outboard motor is quite simple. Here’s what you need to do,

  • Remove the electrical cover
  • Open the fuse holder
  • Use a fuse puller to remove the fuse
  • Put a new fuse in place of the blown one
  • Put everything back in its place

Now try turning on the engine. If the fuse was the issue, replacing it should also bring back power to the fuel pump.

Reason 3: Dirty VST

The VST (or Vapor Separator Tank) is a filter that refines gas before injecting the fuel into the fuel injection rail. The fuel passes through this part to get to the main engine. If the VST is clogged with dirt, the fuel won’t get enough space to channel through to the main chamber.

Solution: Replace the VST

Cleaning the VST is certainly an option. But it’s just not worth it. Having the VST filter clean keeps it working only for a while. Then it all gets back to square one. So the best thing would be to replace the entire VST.

Here’s how to do it,

  • Remove the fuel lines
  • Remove the VST tank from the motor
  • Unscrew the bolts along the top
  • Put the old filter away
  • Install a new filter in place of the old one
  • Put everything back in their place

Now with the new VST, the fuel pump should work perfectly fine.

It’s Always best to take professional’s help for replacing the entire VST

Reason 4: Clogged Hoses and Fuel Rails

The fuel rails and hoses pass the gas through these channels and get the fuel to the right tank to get the fuel pump running. If these passages are blocked in any way, the energies won’t pass through. As a result, there won’t be any power in the fuel pump.

Usually, with time, the fuel rains, and hoses get clogged with dirt and debris.

Solution: Clear Out the Fuel Rails and Hoses

The safest way of cleaning the fuel rails is to use a vacuum cleaner.

Detach the fuel rail and the hose from their connection first. Then, just attach the vacuum cleaner to the hose and turn the machine on. It will suck up any debris stuck in the rail. Do the same with the hose. Now the hose and channel should be completely clean. 

If applying a vacuum doesn’t work the first time, do it again. But never use water to clean the channels. This will damage the whole engine.

Reason 5: Clogged Fuel Injector

The fuel injector is a system that supplies just the right amount of gas at the appropriate time. However, if the injector gets clogged with too much gunk, it will fail to ‘inject’ the fuel into the tank. As a result, fuel won’t reach the system, and consequently, the fuel pump won’t work.

Solution: Clean the Fuel Injector

You can always replace the fuel injector, but that would be an expensive fix. The wise decision would be to put a bit of effort and clean the clogged fuel injector. Here’s how to do it,

  • Locate the fuel injector in your outboard motor
  • Disconnect the fuel pump from the fuel injector
  • Disconnect the pressure regulator
  • Use a soft-bristled brush to clean excess debris from the surface of the fuel injector
  • Spray cleaner through either side of the fuel injector
  • Reconnect the fuel injector and the rest of the components you previously disconnected

If the process went perfectly well, as mentioned here, the fuel pump of your BF22 should get power again.

What To Do When Nothing Works?

The previously mentioned issues are not actually the responsibility of the fuel pump. It is the surrounding components causing the problem of the power outage.

But this doesn’t mean the issue can’t be with the fuel pump. It is possible that the fuel pump itself is faulty. In this case, you may have to replace the whole fuel pump. Here’s how to do it at home,

  • Locate the fuel pump in your BF225 outboard motor
  • Remove the fuel tank and make sure there is no active power connection
  • Relieve fuel system pressure
  • Drain as much fuel as possible
  • Disconnect the filler tube line and the electrical connections
  • Unscrew the bolts holding the fuel pump in its place
  • Install a replacement fuel pump in place of the old one
  • Screw up all the bolts
  • Connect all the electrical wires, fuel lines, and hoses like they were
  • Refill the fuel tank and conduct a test to see if the engine is running again

With the new fuel pump installed, your BF225 should now run perfectly well.
