My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
The first thing that needs done is to check over the vehicle to see if this is caused by an issue with the engine install.In most cases this will be the cause with an electrical wire left loose or possibly damaged that causes this here.If you have already checked over the install and no issues were found let me know.
Thanks Pete

I double check all the wiring and there is a big ground that is attached to the transmission that I was suspected that can cause the problems.
