Joyner UTV SxS Forum

I have a 2018 TW450E that runs in my yard and slow good just will not go down the road seems to be running out of fuel where should i start? I have replaced both fuel and air filter drained gas and tried a small auxiliary tank same issue i have ordered a new vacuum fuel pump to try next anyone in Texas that works on these?

I have a Bennche 700 EFI Bighorn. I’ve recently been unable to get it to start. After a little troubleshooting I realized my fuel pump was not pumping fuel. This weekend I emptied the gas and replaced it with new. I replaced the fuel pump, fuel filter and fuel injector. I also replaced the battery, spark plug and made sure all my fuses and relays were good. I have confirmed that the float on the fuel pump is not obstructed. The UTV is about 12 years old and has less than 100 hours on it. It has not run in over a year.  Not sure whats going on?!? After doing a little reading I'm leaning towards it being an issue with the ECU or perhaps a faulty wire in the wiring harness. Anyone have any ideas on where to start looking or what I could be dealing with? Any help is appreciated, thanks in advance!

I've discovered the part number in question schematic callout (210-253) is actually 280-62358-08.

The needle adapter shown in the first post makes it so you don't need to be straight perpendicular like with a traditional grease gun coupler, You need to make sure you're buying the blunt type like that, there are also sharp needles meant for piercing rubber in ball joints, etc. With the blunt needle adapter you basically shove it into the check ball. It does make a bit more of a mess than a normal coupler, but it does fit. The driveshaft zerks are certainly have limited clearance. The other option is a small grease gun that just fits on top of the zerk without coupling. You can see one pictured in the "rear driveshaft" pic Something like this

Ok so lets start off simple on the instructions I posted above. I'm assuming you have a Volt/Ohm meter, if not you'll need to get one. If you find something wrong in any of these steps rectify, and then try starting again. Just so we're clear, how are you checking for spark and determining that you don't have one? Are you sure you have the key wired up correctly to the proper terminals?   -First check all the fuses. There is a fuse on the positive battery cable. The remaining fuses are inside the box forward of the battery under the seat. Remove the cover (4 Philips screws) and check each fuse for continuity. -If those are all good, next step is check the battery. Should have 12.5V or more. If it doesn't charge it. -Next step is to inspect the plug, make sure it is clean, not fouled, and gapped properly. If it's still in new condition, and not soaked in gas it's likely OK.   Let me know the answers to above, and confirm all those steps are complete with no resolution.
