I have a 2015 rtv500. Was told it has a blown head gasket. Compression check and holds 180 on both cylinders. Put new plugs, fuel pump and fuel pressure is 35lbs. Verified injector spray. Timing is correct. It tries to start but wont. Verified fuel return and tank vent. Choke is working. Any help would be appreciated.
 
Disable the fuel injectors put a dash of 30wt oil in the cylinders take off the intake tube and give it a shot of either while cranking? Might take the exhaust manifold loose at the head?
 
I pulled the plugs after trying to start . They are wet. It is firing as i texted both removed and grounded out. Each plug has good spark. Could the injector be flooding motor? When i remove injector and watch the spray while spinning over there seems to be a lot of heavy drops instead of light mist.
 
Thats why i asked for you to disable the injection and test on either. If it runs on either then your problem is just fuel mixture. If it doesn't then you may have an ecm problem that could be fuel or timming. Try the either trick.
 
Tried either but didn't work. I assumed the wet plugs were gas. After using a lighter to see if it is gas, it's oil. Even though I have good compression possibly a leaking head gasket
 
Try this. Take out the plugs and squirt some gasoline into the cylinder and crank with the plugs out. Do this a few times to clean the oil out of the rings and then reinstall the plugs and try to start? If it runs but smokes horrible and doesn't clean up your rings are shot most likely?
