Are you sure it's meant to have power to it all the time ? Does it perhaps have a permanent earth ?

Some engines have power going to the injector all the time the key is on, and then the ecu earths the injector momentarily when they want it to inject. Other systems though have a permanent earth, and then the ecu sends a momentary voltage to the injector when they want it to inject. Perhaps this is one of the latter..

Do you have the service manual for this thing ?

And.. what is a massimo ? Is that a make, or a model of quad ?  Is it a quad ? haha..  I've never heard of that before.

Ok.. I found the dealers site... so you'd better give us a bit more info.. is it side by side or two wheels or quad..  Does it have a model name or designation ?

Thanks for your response Massimo is a Brand Name 4X4 UTV, before I started having a problem I installed a new injector at that time if I turned engine over injector would spray fuel but now it will not. I do not have a service manual.

Well I haven't found a service manual, but that site has an owners manual for it which has a bit of trouble shooting suggestions. Unfortunatly the owners manual doesn't have a wiring diagram.. But, since the problem has only arisen since you did some work on it.. I'd suspect it's something you've done..

So, first thing would be to check that a wire hasn't broken where it goes into the injectors plug. Best way would be to trace the colour of the wire back to the ecu, and then use an ohm gauge to test from one end of the wire(from the ecu), to the other end(the injectors terminals inside the plug). If you can't trace the wire, use a pin and poke it into the injector wire a little way back from the plug and check from the pin to the injectors plug. That's just checking that there is continuity through the wire and into the terminal itself. You should do a similar sort of trace and test of the earth wire too.

Try that and let us know how that goes, and I'll see if I can find a wiring diagram or service manual.

There are a few other things we should check..  After you changed the injector did you bleed the air out of the lines by turning the key on and off several times ? And, are you really sure there's no power, or are you just assuming that because a new injector isn't doing what it should ?

If you put a finger lightly on the injector, can you feel it click/pulse when you crank the engine over ? It's only a very slight click you will feel, use a light finger. If the engine was running, you'd be able to feel the injector make a click as it injected.. cranking it over might make the engine shake too much to be able to feel it but it would be a good idea to check that if we can if it's only the lack of fuel that you are sure about..  Perhaps the injector is getting the power, but it needs bleeding, or it might be faulty.. It happens occasionally !

Try and verify there is fuel to the injector, loosen the coupling perhaps. And try to feel for the click.. If you took the injector out again you'd feel the click.. but it's a bit of a fire risk.. Be careful.

According to the owners manual if there is an electrical fault the dash will flash..  Is it flashing ?

This is a twin cylinder right ?  So does one injector squirt ? Did you change both injectors ?

MECH PROBLEM SOLVED thanks so much for your help turned out to be a bad wire going to injector and dirty electrical plugs and/or not all plugged in all the way.

Merry Christmas

thank you so much

      Starter circuit cut out relay 1997 Yamaha Big Bear 350 4x4
      By crankin
      I have a 1997 Yamaha Big Bear 350 4x4. It used to start right up. Then all of a sudden it wouldn't crank. I have a schematic for it so I started tracing the problem. I had no power at the starter solenoid. According to the schematic the power comes from the neutral switch and through the starter circuit cut out relay. I cannot locate the cut out relay on this machine.. If I apply power to the relay it will crank with the start button.
      The neutral switch is hard to get to with all the brackets on this thing. I did find out from all my research that if I apply the rear brake lever it will start.
      Does anybody know if the cut out relay exists and where it might be found?

      1990 fourtrax 300 no power no lights
      By Adamb2025
      I have a 1990 Honda fourtrax 300 2x4
      I rode the other day for 30-45 min. Switched it off and now it is completely dead..
      battery is fully charged, fuses are good . WILL NOT TURN OVER ,
      headlights won't turn on , No neutral, reverse or oil temp lights . Electrically it is completely dead !!! I replaced the key switch and CDI box , STILL NOTHING.
      I bypassed the neutral safety switch and grounded it to the battery and still nothing !! I used a jumper wire on the starter Solenoid , the motor will turn over but not start . I even bypassed both fuses and straight wired it to see if I could get a neutral light or headlights still nothing . What could it be ?

      2006 LT-F400F stator/generator cover change: What is the best way to check that all is good with the transfer operation before reassembling?
      By middlebrookgt
      I have replaced the cracked stator cover on my non-running 2006 LT-F400F that I purchased recently, checked all the shafts vs the service manual and pics and advice here.  I replaced missing gears, bushings and washers, made sure that truth marks were all aligned properly, that the shift cam springs felt like they returned properly, etc.  IAfter installing the new stator cover I checked the transfer lever for proper movement from L-H-R and then cranked it up.  Happily, it runs and changes gears well in L,  but it will not shift into H or R for anything.  I have opened it back up and am going back through it looking for the missing puzzle piece(s) but how can I best check that I have everything right this time before buttoning it back up?
