Massimo 550L no fuel injection or sound

When I first bought the Massimo 550L, everything was great until we stopped in the woods and it just wouldn't start again.  When the key is first turned and the kill switch is on, you hear a magical sound that tells me the fuel injector is ready to go and may have put fuel in the start process.  The same sound happens with my ducati motorcycle.  When it wasn't working, the sound never happened.  They after fooling around with the electrical harnesses, etc, put a new fuel injector on, it worked.  Fastforward 9 months and the same thing is happening.  It started this morning Nd the magical sound was there before I started the engine.  Later in the day, no magical noise.  Can anyone provide advice?  Thanks

      This is an interesting read. ADAS is main stream on cars these days. The technology looks to be headed towards UTVs and Off-Road Vehicles.
      Potential Motors and CFMOTO USA have announced a new partnership to integrate advanced driver-assist systems (ADAS) into recreational off-road vehicles for the first time.
      Sam Poirier, CEO and co-founder at Potential Motors, says the integration of its technology into CFMOTO’s vehicles will set new standards in the side-by-side segment. (Photo: Potential Motors Inc.) The partnership will first see Potential’s tech integrated into CFMOTO test vehicles. The companies will conduct extensive real-world testing at Potential’s purpose-built off-road proving ground in Fredericton, Canada, and CFMOTO facilities.

      starts up you have keep rpms up for 5 minutes till it warms up then runs fine. But if it stalls wont start unless you unplug fuel pump and hold it to the floor till it starts then plug pump back in and run it till it warms up then it is fine all day.

      I have a 2019 T-Boss 410 that died one day after we parked it. It had been getting harder to start (had to hold the throttle down) for some time but would not start. The starter clutch seized while I was trying to start it. I replaced the starter clutch and it will not start. It appears to have solid fuel pressure and solid spark. It "fires" but will not actually run. The exhaust gets hot after cranking so I know that's actually firing but it won't fully start. Any ideas?

      Does any have a part number for the fuel pump sock for a 2016 challenger 700 efi. Does not show on any parts diagram but the old pump has one on it.
