(SOLVED)
I have 2 1998 zr580s with a battery and fuel injectors. they were sitting in a shed for almost 2 years now until a firend wanted to borrow them. i took them out, replaced the batterys, drained the old fuel and one started right up and ran great until the axle shatterd, long story. but the other will start up and idle low, then high, then it would steady at about 3000 rpms. as soon as you give it gas it revs down. Then when you let go it will rev up to 4000 rpms and move like an inch.
here are things i've already tried
Im at a loss of what to do.
EDIT: the fuel line conecting the fuel pump in the gas tank was all rotten and was only letting a bit of gas in it. i replaced the tubing and it worked flawlessly
thanks for all the help from everyone, it really helped me pinpoint the problem
Thanks- Mason

here are things i've already tried
- checked cdi box, one red blink
- swapped fuel injectors with ones from other snowmobile
- swapped spark plugs from other snowmobile
- recharged battery
