I bought an Arctic Cat 550 alterra xt 2015.
Error: starts cold, but as soon as it reaches 45 degrees Celsius it does not start just drive the starter.
-Do not write an error code.
-It has compression.
-It has sparks.
Thanks for the help !
Fuel pump runing
-Valve clearance ok
When plugged into the engine temperature sensor it operates a 2.2k ohm resistor, it feels 24 degrees Celsius. I added a new factory temperature sensor, but it's not good either.
Coolant level is OK. Cable is not shorted. Above 45 degrees Ceslius it does not start and stops. When I unplug the water temperature the meter starts but fluctuates at idle. It goes up to operating temperature by holding gas.
That all seems okay. Have you tried to sync the EFI system?
The procedure follows:
1. With the key off, depress throttle lever to Wide Open Throttle (WOT).
2. Place the ignition key in the ON position and wait for 10 seconds.
3. Release the throttle lever and wait an additional 10 seconds.
4. Turn the key to the OFF position and allow the gauge to shut off.
