Ok so here is the problem i am having my sled will run great sometimes and then other times it will just not have spark it will do these things whenever it wants some days ill go 100 miles without a problem other times ill go 2 and it will die and have no spark then a couple minutes later it will fire back up again pritty lost with the problem right now so far i have replaced the voltage regulator and stator with no luck i have went through all of the wiring with no luck in findind a short anyone know the cure? The codes i got from running a diagnostic are these po335 po336 po546 p2147 po118 if anyone has a clue what it is let me know thanks

I have tryed that already with no luch any other suggestions?
P0335 5-tooth CPS signal missing. Engine is running but there is no signal from the 5 tooth CPS. Can be caused by a faulty stator, wiring or ECU.
P0336 5-tooth CPS signal intermittent. Engine is running but the pulses from the 5 tooth CPS are incorrect. Can be caused by a faulty stator, wiring harness or there is no 2 tooth CPS signal. If there is no 2 tooth CPS signal, the engine will not run, but the P0336 code will be set because the ECU receives extra 5 tooth signals without 2 tooth signals.
P0546 Exhaust temp sensor circuit voltage high. Sensor signal is above 4.9 VDC for at least 2 minutes and the engine has been running at or above 3000 rpm.
P2147 Fuel injector voltage too low. Engine is running but the injector voltage is below the acceptable limit. Can be caused by faulty wiring, ECU or stator.
P0118 Engine coolant temperature sensor voltage high. Sensor voltage is above 4.8 VDC. Can be caused by a faulty wire connection or faulty temperature sensor.
(CPS is the crank position sensor. 5 tooth is for ignition timing and 2 tooth locates TDC and RPM.)
Taking all the above into account I would suspect wiring harness issues or ECU connector issues. Check for loose pins in the connectors or pins that have pushed back into the connector housing. It is somewhat puzzling that some codes are due to high voltage and some are due to low voltage. Good luck.

Thanks for the information i will take a look at the pins on the ecu ! By the way i replaced the regulator and stator after these codes and havent had it read since but what do you guys think ecu probably? Or something else? I have went through every wire on the sled and have not seen any sighn of rubbing or anything even had the switches apart thanks for the advice!
Yes it could be a faulty ECU. Possibly a hairline crack on the printed circuit board or a cold solder joint etc. I haven't really got into an ECU in any great detail.

air gap at the crank sensors are to great? should be .020 or bad ecu connection? really look at the pins, plug, etc. you may have to replace the ignition/injector harness. the small plug at the ecu. these have been know to cause issues.
