This answer was rated:

Kawasaki Mule, 3010 4X4, No power to fuel pump, but have power on the fuel relay. Where else could problem be?

Kawasaki Doug :

Hello

Kawasaki Doug :

The relay is triggered from a signal coming out of the igniter.

Kawasaki Doug :

Fuel pump power comes into the relay from the ignition switch and the igniter operates the relay.

Kawasaki Doug :

Verify that you have power coming in on the bk/w wire. When you crank the motor, power should exit on the bk/bl to the fuel pump. If you have 12 volt power coming in and you have a new relay, then you will have to check the wire from the igniter. Also check to make sure you have spark at the plugs.

Kawasaki Doug :

That is the relay test information.

Kawasaki Doug :

The signal from the igniter also goes to the #1 coil. Check for spark on that plug to make sure the coil isn't bad.

Kawasaki Doug :

Let me know what you find.

Customer:

Hi Doug,

Customer:

Have power coming in on the bk/w wire, but no power going out on bk/bl wire when cranking

Customer:

I have not replaced the fuel relay

Customer:

Only checked it to make sure I had two hot and one gound

Kawasaki Doug :

Check for a pulse signal on the wire from the igniter and do the relay tests. Either the relay is bad or it's an ignition problem.

Customer:

I have pulse signal on the igniter wire and spark to #1 plug

Kawasaki Doug :

That's good. The problem should be in the relay then. If you have an ohm meter, check the relay. That should be the faulty part.

Customer:

ok Thanks. Don't have an ohm meter. I'll order the relay and see if that takes care of it

Kawasaki Doug :

Let me know if you need more help.

Customer:

will do. Thanks

Kawasaki Doug :

Goodnight
