No power to fuel pump

**SMOKEU** · 19th October 2009, 10:20

My MC19 fucked out on me so me and a mate figured out that the fuel pump is not getting any power. Does anyone know what could be the cause of this? Or is the fuel pump fucked?

Bad earth connection?

Easiest way to test it is to 'hotwire' it across a 9v battery, or you can check for continuity with a multimeter.

Agreed.

You need to check to see whether there is no power to the fuel pump or maybe the fuel pump is knackered.

Have you checked the fuses?

After checking the Earth, check the live cable at the fuel pump and and then work your way back until you do have power.

It could just be a simple wiring mod that is needed, which will be a lot less expensive than a new Fuel pump.

Fingers crossed.

Are you sure the MC19 needs a fuel pump? Honda fitted them to many bikes that actually run as well (or sometimes better) without them. If the fuel pump does prove to be faulty, and there's sufficient fall for gravity feed to work, you should be able to remove it (may need to replace some hoses though).

As far as I'm aware, the MC22 does not come out standard with a fuel pump, whereas the MC19 does. I've heard that removing the fuel pump on the MC19 makes them starve of fuel when the fuel tank is less than 1/2 full. Is the computer connected to the fuel pump in some way, or does it operate independently?

check for spark...

unplug the out from the fuel pump... and see if it squirts out everywhere..

just dont let r6_kid test ride it

It's got good spark. We unplugged the outlet on the fuel pump and it's not pissing out with fuel.

Does the fuel pump have a relay? If so, where is it?

**Rodney007** · 19th October 2009, 20:22

if i was you id just cut the wires, hardwire it and see if it makes noise

I have the fuel pump from my 4AGZE that should put out enough fuel.

yeah the gas consumation of the 250 must be near what the trueno used...

I might even try my old GTI-R fuel pump then.

On my GSX1200 the fuel pump died, I just bypassed it. Apparently if I try to run it at sustained speeds of over 220kph it may not be able to draw enough fuel through and I may need to pay $700 for a new one, luckily I don't ride quickly enough for that to be a major problem. If you notice the difference when the pump is bypassed on your 250 I would be very suprised.
