Q-Link Fuel injector not working

Recommended Posts

I have a Q-Link (Rhino clone) and the fuel injector won't open up and spray. The fuel pump is brand-new and kicks on and primes to the injector but nothing comes out.

I've cleaned and dielectric greased the electrical plug and the ECU plugs but no change. not sure where to go from here. Any help?

I'm curious, how did you check the injector to verify it wasn't flowing? 

First thing I would do it stick an ohmmeter on it and look at the resistance across the injector.  I would imagine somewhere between 5-50 ohms.  Then I'd check voltage coming to it during start up to see the "pulses".  If I've got voltage, but no squirt-squirt, bad injector.  If the injector is pulsing but not squirting, its clogged.  Either way, new injector.

Also, you don't want dielectric grease on the metal contacts themselves.  You want it around the seal of the plug, not on the contacts.  The grease itself is an insulator.

Thanks y’all! I took the throttle off and felt inside the boot and it wasnt wet. I then removed the injector from the boot and turn the key on and nothing sprayed. 
idk how to test for voltage. I assume ground one lead and test one on the prongs for power?

I couldnt get a good read on the electrical plug because my leads are too big to touch the contacts but today I put 12 volts directly from the battery to the injector and it clicked but still didn’t spray.  So there may still be a problem but regardless I guess I need a new injector anyway. :(

Woah now, of you put 12v on it and heard/felt a click, it might not be the injector.  Was the fuel line pressurized? I'd suspect a fuel pump before I suspected an injector.

It did click and was pressurized but nothing came out. The fuel pump is new. 
I bought this for $500. It’s been sitting for like 6 years and so many many dummy’s have messed with it that things were out of sorts. I believe I’ve got ever in order again. It only has 23 miles on it. 
I ordered a new injector. Should be here in a couple days.

Ok, well let us know how it works out.  Keeping troubleshooting and results active in the forums really helps out other people whether or not they post on here.

      Hey guys.
      I have a 2009 hisun 700 I bought bout 2 weeks ago and it was running fine but was hard to start but once warm it fire rite up  i took the  air filter off and it was nasty so I gave it a good cleaning and it hasn't started since. Its cranking over really slow I replaced the starter. I also replaced the batery. It acts like its not releasing decompression  I found a service manual on line and downloaded it and it said the intake valves setting .010-.015 mm  and exhaust is .015-.020 and they all was set on .008 intake and exhaust. And the timing is set I set the intake to .012 and exhaust to .016 and it still cracks over really slow I'm lost and don't know wat else it could be. Anyone have any ideas.  And help would be great thanks .

      Hi,
      Don't know much about anything utv but I figured out my fuel pump wiring harness needed to be replaced. Installation looks pretty straightforward, plug into fuel pump and plug in the two pigtails. Question is: one of the Pigtails on the old harness I am replacing had a splice in the black wire and attached to a bolt on the engine. Is this necessary?  Is the black wire, I'm assuming it's the ground, grounded at the other end of the pigtail?

      Hello hisun owners! I love my utv.
      but as well other utv types mine needs some help from time to time.
      the voltage regulator fried  a pin hole on the plug it goes into. There are 6 pins on voltage regular so I am trying to find the plug that it connects to. No luck online.  Called Coleman company and waiting for help to replace plug. 
      Anyone have a clue where I can buy a new plug?  I use my utv for several projects and need this fixed fast! 
      Thank you for any helpful replies.
