Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
Was the engine coolant temp sensor ever replaced as I assume this is the engine coolant temp that is moving to the red am I correct?
Can you tell me what all has been done to try and locate or repair this issue here at all?
Let me know so we can continue,thanks Pete.
If this is the engine temperature gauge that is moving into the red like this here the most common cause is the engine coolant temp sensor itself needing replaced or an issue with the wiring leading to the temp sensor needing checked for any damage and repaired as well as the engine coolant temp sensor connection checked for damage or corrosion needing replaced.
In most cases it is the engine coolant temp sensor itself that needs replaced and on this model this can disable the engine starting when the engine computer thinks the engine is hot like this here.
I would start with having this sensor replaced and the wiring and connection checked at and leading to the sensor for any issues needing repaired or replaced as well.
