kubota rtv 500
Massimo 500 will only crank when I jump solenoid with screwdriver cranks right up and runs great. But won’t start with key doesn’t do anything when I turn the key. Only thing it does is power everything as in dash and fuel pump then have to jump solenoid to crank up and drive.

OK, here's the mystery of the day. I was using the UTV the other day and the idiot light came on that said it was overheating. I immediately shut down and checked the coolant. No coolant! I refilled the overflow reservoir and the radiator and all was fine. 2 days later the light is on again. I rechecked the radiator and it was again empty? Bone dry? Now, here's the weird part, There is no coolant anywhere on the floor below the vehicle. I can't even see any on the frame. I have it up on the lift and am getting ready to start tearing into the bottom "skid plate" to see if the leak is in the hoses there. Any suggestions as to where to start? I have yet to begin and I am already baffled!
My T-Boss 410 died hard on a run up the driveway and wouldn't restart. Cranks over fine, 12v at coil, fuel in cylinder (from plug check), and wire from computer to coil buzzes out OK. Computer threw a P0351 ignition coil malfunction message. I pulled the coil, measured resistance across the primary, and it was about 0.8 or 0.9 ohms, nominal for most ignition coils. I measured the secondary resistance as well and got about 6.5K ohms, also nominal for most coils. I checked the plug wire resistance and it was about 5000 ohms, which seems OK. And really perplexing, my spark tester shows spark. I got to feel it too, when I held my fingers too close to the conductor. 💩! Have any of you folks run across this?
My 2014 Bobcat 3650 has started running rough. It starts fine. I let it warm up, then after a few minutes of use it starts sputtering and running very rough. Then stalls. It usually will start back up but continues running rough. If i let it cool off, it will run fine again for a few minutes, then repeat the process.
I recently purchased a new Kubota RTV520. When i try to start it i have to do the cold start procedure every time. Once it is running for a few minutes i can restart it without any issues.
The cold start procedure is turn the key to start position and let the fuel injection system turn on and stop. Crank for 10 seconds and if the unit doesn’t start, turn off and repeat the process 30 seconds later.
If it hasn’t been used for a week and i try to start it i have to repeat the cold start procedure at least 3 times until i get a successful start.
The dealer says this is normal and its not a malfunction on the engine. I feel like its weird for a new machine to have this starting routine.
I live in south Texas so the weather is not extremely cold.
Is ANYBODY having this problem? I am contemplating returning the UTV but i want to know if this is a common problem with the new 520 model.
