pantera no starrt

[pj4]

i have a 95 pantera with 583 efi. the sled started after several tries this fall, ran for 10 min. stumbled once then i shut it off. now it wont start again,no spark. tried new cdi box, no hlp. looking for wiring skimatic for the coils, cdi,ect. not sure how to check each componet,. the coil has continuity. was think its a broken or loose wire, found nothing. this sled ran flawless for years.

Could be that pesky throttle safety switch. Squeeze the throttle just a hair while testing for spark.t

New battery? Those battery EFI systems were finicky if the battery was not tip top. I know owners of those old EFI's that replaced the battery every year weather it needed it not to be on the safe side.

the battery is fully charged, tried moving the throttle and still no spark. how do you test the throttle position sensor? it has three wires, using an ohm meter and watching for a change in resistance as the sensor moves? just hoping its not the ecm. the kids are bugging me to get it running for them, i feel so bad for knowing so little about artic cat wiring.how does a person test the ignition timing sensor? thanks for any help.
