We have a kawasaki mule 2510 and have no power comming out of the blue and black wire come from the fuel pump relay and relay is new

whats everything -- also check fuel pressure new doesnt mean free from defects this link and quite a few 610 owners have been complaining about same problem for years but go through test and check the basics first--plugs -wires-filters-oil level --wiring --carb settings --battery https://www.quadcrazy.com/atvforum/topic/14998-2005-kawasaki-mule-610-sputters-going-uphill/ also this link has service manual download https://www.utvboard.com/files/category/11-kawasaki/ https://www.utvboard.com/files/category/11-kawasaki/

The fuel pump relay (circuit opening relay) has 5 wires.
black white is power from a 10amp fuse
black orange is power from the EFI relay
green and red is the signal from the computer
black is ground for the relay
blue black is power out to the pump
Which wire are you saying has no power ?

Do you have power coming into the relay on the black orange wire, and then out to the pump on the blue black wire ?

gotta start with the color code of the wiring. verify that is correct first. you have to have fuel pressure for it to run obviously so make sure you wired it correctly. Here is the color code according to Mitchell OnDemand
black/orange= ground for fuel pump
orange/red=power on for fuel pump(only gets triggered from fuel pump relay)
dark blue/white= signal to pcm for fuel level
dark blue/ dark green= ref voltage

If that is ok then check for relay activation. Fuse 17 is the power source for that relay. If you have a good fuse but no relay activation you could throw a relay at it but if that doesnt do it then its gotta go to a shop. But if you are curious....
Relay code
pin 30= hot at all times
pin 86= relay control trigger from the pcm
pin 85= hot in run or start
pin 87= power source to fuel pump.(i.e. orange/red wire)

the relay will have numbers on it designating the correct pins. Get that right first then move on to the next. I'll be here. Good luck!

Of the 3 relays, one is the Fuel Pump Relay . wires are White/Red, Black/white, Red/black, Black/blue. Black/white and Red/black should have power with key on. Black/blue powers the fuel pump. The computer grounds the White/red to turn the relay on.

honda's have a problem with the main relay that turns on the fuel pump its located by drivers left foot could be mounted near streering column. if you can solder you can open main relay you see spider cracks in solder . you can resolder it and it will last for ever,these are 40-50 bucks a peice wish honda learn to solder these better.

Hello Hooverman.

There are quite a few items that are possible causes.
The EEC power relay is probably shutting down for some reason.
This relay, when shut down will turn off power supply to injectors, the fuel pump and a few other items.
This relay is mounted on the top of the left front fender under a plastic cover and has a brown base with a black top. The fuel pump relay is beside it and has a green base with a black top.
The large yellow wire into the power relay should have constant 12 volts positive power.
The white/light blue wire should have 12 volts positive power with key on.
The black wire is ground/negative.
When the key is on the red wire is activated to 12 volts positive.
Verify those circuits and you will find the problem.
Often I have found corroded splices in the yellow feed to the relay. You will need to open the harness out and trace back to find those splices. There are two of them. This corrosion will often cause intermittent connection.
If you need further advise on this problem please ask me in a comment here and I will return to assist you.

Thank you for using FixYa.

The blue wire changes to Blue/White. It gets power from the Fuel Pump Relay. Fuse number 11 is the power source. The relay is up under the dash panel, blue connector

Did you verify that the relay terminals have the appropriate signals to them? 

ECM fuse B (20-amp) should provide power at all times to the orange wire of the fuel pump relay. The relay coil receives ground via the black wire, and relay coil gets power from the dark green/white wire. When the relay is closed, you should have battery power on the gray wire. 

The relay trigger wire should have power from the dark green/white wire in terminal 1 of the Vehicle Control Module (VCM) connector for the first couple of seconds after they key is turned to run (to prime the system) and when the truck is running. Checking for all the appropriate signals at the relay is where I would start. That is after I checked for diagnostic codes.

Believe the fuel relay is the middle relay out of the three in the left rear of the glove box. Last thing is to hot wire the fuel pump if you can not get it scanned, see if the pump is bad unless your going to have a shop work on changing the fuel pump.
Good luck and hope this helps. keep me posted.

there are two fuse locations, under the dash by your left foot, and under the hood behind the passenger side headlight.

Your question is really NOT that easy to answer, there is no stock location for a "fuel pump relay" fuse, the fuel pump is powered by power coming from the MFI relay.

Fuse #1 under the hood supports the MFI relay as do fuses 1 and 12 under the dash. Check all three.

There are reasons a fuel pump won't start that are not related to the fuse... if you check them and determine that the fuses are not blown, with the ignition turned to the on position, try powering the fuel pump test jack, if your fuel pump comes on, it is something else (probably a bad cam/crank sensor)

To power the test jack, run a test wire from the positive terminal of the battery to the connector stuffed down behind the passenger side strut tower between the strut tower and the fire wall. It should be a black connector connected to a single black wire with a BLUE stripe. There will be three connectors bundled together, a black one, a blue one, and a round brown one (the round one is for setting timing and the blue is for setting idle, do NOT mess with them)

When you power the test connector, the fuel pump should come on, regardless of the MFI relay or the fuses... if it does not, you need a new fuel pump.
