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.

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

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 ? 

No sir its a single cylinder

Hello everyone. I have a 2015 Massimo 500 Gator side by side EFI  I have no fire going to injector, before problem started I replaced injector at that time if I turned engine over the injector would spray fuel, it will not now. On this vehicle I have replaced coil, coil wire, fuel pump spark plug and relay checked fuses and did a visual inspection of wiring finding no problems. 

Will appreciate any help or tips in locating problem

Have a Great Day

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 ?

Thank you its a Massimo Gator 500 UTV

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.

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.

Massimo 500 no fire to injector have replaced coil coil wire relay and injector still no power getting to injector have checked all fuses any ideas will be greatly appreciated'

Thanks to all
