Ronnie Posted January 22, 2020 Share Posted January 22, 2020 Welcome to the forum Todd!! You should check to see if there are any trouble codes stored in the ECM and post the codes you find. That is the first in diagnosing your problem. Instructions for checking codes can be found here. Link to comment Share on other sites More sharing options...
