I'm working with a 2015 MSU-500. Basic symptoms are it cranks well, but will not fire. It has spark, and it has fuel spraying out of the injector (and spraying starting fluid into the throttle body and plug hole makes no difference). It has compression. I bought it not running, and no other information was available. It has 775 miles on it and 127 hours. It looks to be in very good shape. Previous owner replaced fuel pump, ECU, coil, plug, and the fuse/relay box that mounts on the firewall, then gave up.
My questions relate to cam/valve timing, considering the symptoms and diagnostics so far. My thinking was the woodruff key sheared off and the crank spun, making it out of time. My question is, by the pictures attached does anyone have an opinion as to the cam/valve timing being correct? In the crankshaft picture you can see a timing mark visible. In the camshaft picture I have arrows directed towards what I think are timing marks (which appear to be exactly 180 degrees from one another). However, the long arrow in what appears to be bolt configuration in line with the piston/rod line. Here is a puzzling note... in the position you see in the pictures... I have valve lash on both the intake and exhaust. I think it's at TDC, given the visible crank timing mark and valve lash on both valves.
Any thoughts ? Does this appear to be in proper valve time ? Have I missed anything simple ? Thanks in advance for your input.

Hi
I have a 2022 hisun sector eps 550. 30amp fuse is blown for eps. Checked the motor and it’s fine. Opened up the controller and found a bad diode. Dealer wanted 500$ for the controller. Just posting this in case it helps someone. I couldn’t read numbers from the old one so just took a guess and replaced it with a 100v 3amp diode.

I had to remove the relay for the dump bed due to it popping the fuse for main key power. I have tried to find a short but nothing seems to out of normal. I also disconnected the dump motor and switch and still pops the fuse. Also, when the machine is warmed up i get about 5 to 10 of work out of before it stalls. Once I can get it to start again I have to use the choke to keep it running.

My Axis 500 has been operating properly for almost a year with Zero problems. While I was away my granddaughter & friends were riding & playing in the snow. They went to the gas station to fill the tank & the vehicle would not start afterwards. I BEEN GIVING MULTIPLE STORIES: The ATV will not start. When I turn the key I can hear the fuel pump come on but nothing happens other than that.
- NO CLICK - NO OTHER NOISE
*I CHECKED THE BATTERY 12.43volts
*I replaced the solenoid inside the battery compartment.
Seems the next electrical component in line has battery connections IN & motor connections OUT with 2 other small wires connectedaswell(I do not know the name of this component).
Can anyone help?
I can not find an ordered list of electronic components starting at the battery.
Can anyone help with this?
Thanks in advance for any help.
