I'm having a issue I cant fix my sled started running rough won't idle and was flashing code 14. I did some research and found that it was caused by blocked line comming from the fuel pressure sensor on-top of the throttle body I tried blowing the line out as well I tested both the sensor by the ecu and the sensor by the throttle body both are reading 3.5 volts with the key on I've let the sled thaw out and checked for air leaks and cleared all codes and a code 20 od come back on when I start the sled or after it warms up ..any help would be greatly appreciated
