I have a 1999 Evinrude 115 Ficht motor, and I am having issues purging the air in the oil lines. I am using the Evinrude diagnostic software to trigger the oil injector, and it clicks but won't let any oil through. I have verified the oil pressure all the way up to the inlet to the injector. I have also bypassed the oil lift pump to see if it was restricting the oil flow. During the attempts to purge/prime I have triggered the oil injector while pumping the oil line bulb and restricting the oil return line. I have replaced the oil injector with a new one also. I have the specific services manual for the motor and I have followed all of the suggested steps for troubleshooting with no luck. I have also verified that all of the oil/vacuum lines are connected correctly. The motor will start and idle fine, but there is no oil flow, so I haven't ran it for more than a 10-20 seconds since rebuild. If anybody has any suggestions it would be greatly appreciated.
