1998 zr600 efi ?

I have an arctic cat zr 600 efi sled that has sat here for a couple of years because it lost spark. We've determined it is either the ecu or internal coil, both are expensive, I'm told there is no way to test either except buy the new part and try it or find someone who has one and try theirs. So here I am, if anyone has an ecu that would meet me (im in meridian Idaho) It would be a quick plug and test and then I can determine which part is bad. I would buy your gas or something for your time. Thanks alot.

well we managed to fix it tonight so I don't need to test the ecu.
We took every single electrical connecton apart and used di-electric grease and put them back together and presto we got spark! The sled then fired right up, gotta love that. Thanks anyways.:beer;
