Is there any way to check the ECU and throttle possition sensor? I am only getting spark once in a while..so just want to check the tps and ecu!!!

If the tps was bad would it kill the spark?

yes arctic cat makes a scan tool. Take your sled to the dealer and tell them to check it real quick. It takes 5 minutes to check it.

TPS and ECU are about the last things to check for that problem.

Start by unplugging the throttle safty switch, kill switch, and key switch.

check the wire harness for shorts/broken wires/rubbed through wires

Test the coil, stator, and timing pick up next
