2010 m8 only running on one cylinder need suggestions.

[ilovepowder]

Ok put my sled in storage last spring and it ran fine then. Took it out now it only runs on one cylinder.
I changed the plugs and no difference.
Runs on pto cylinder not mag.
Pulled plugs from.mag cylinder one at a time to check for spark and it has it. Plugs are wet.
Replaced one of the mag cylinder coils with a different one and no difference.
Poured a little gas in the mag cylinder still no fire.
Compression on mag side is 160psi.
Didn't check pto because that one is working.
What should I check?
How do I swap injectors can I just pull them and switch sides?
Check reeds?
What are the ohm readings I can check for on the coils?
Can I ohm anything in the stator?
Suggestions please I'm on my way to island park and need it working.
Thanks.

Thanks for the reply. . I'll check it. Any other suggestions

Would the compression be effected if the reed was bad? It still went to 160

No And do both sides have GOOD spark? like when you pull the rope you should see a feww good sparks from one pull of the rope if your seeing a week spark on that side its probably a pickup coil

Stuck injector - have had that happen a few times now on different sleds after sitting for a while.
Unplug the connector to the injector and take a 12v supply to the prongs just for a second. Should hear it click right away.

Check spark first

Turned out to be stuck injector or water in injector. Switched sides and bad cylinder switched. Took out injected checked with 12v cleaned and blew out and ran great.
