Thankyou kevin. I ended needing a new ecm. Now starts but vaporizor code comes up and machine runs like it got a choke on it and dies. What besides a valve stuck would you recomend I check? or do I need a new vaporizer or boot the system or boot the dummy workn on it lol thx

Code e41 is for the stop lamp switch on the brake pedal

P04?? Is ECM communication error,if you had alot of corrosion at the relay box I would check the wiring going to the ECM from it sounds like bad wiring to/ from relay box to ECM check the connectors at the ECM for corrosion also and for bent broken pins or pins that are not seated All the way in the connector
