My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received 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.

Inspect the wiring running to the engine control module (ECM) and connections at it.If any wiring or connection issues are found this will need repaired to correct this fault here.If all wiring and connections are found to be clean and tight this may be due to an internal electrical fault in the ecm itself with it needing replaced and programmed.If no wiring issues are found let me know so we can continue.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
