I recently bought a 1994 ski doo mach Z not running. No Spark I bought a new stator. I checked for spark it had spark, so i put the plugs back in gave it some either gave it a few pulls. nothing. so i took out the plugs checked for spark. nothing. no spark. what could be the problem?

Here is the run down for testing a no spark issue out of my 98 triple manual. I spent all summer testing a similar intermittent ignition issue and in the end, bought a cdi...done. For electrical issues however, I swear by starting small. Just like the manual indicates, wires and connections are your most likely culprits. Good luck.

IGNITION SYSTEM TESTING
SEQUENCE
In the case of ignition problems, check the following
in the prescribed order until the problem can
be solved.
1. Sparking/spark plug condition.
2. Electrical connectors.
3. Ignition switches, DESS switch and emergency
switch.
4. Ignition generator coil voltage.
5. Trigger coil.
6. Ignition module voltage.
7. High voltage coil output.
8. MPEM voltage supply.
9. MPEM.

As far as 1994 goes, there's the
key/kill/tether switches
coils
CDI
stator

If you had spark then don't now, I'd say it's a switch problem (tether)
