Re: Problems running at operating temperature
Today I recharged the battery and started it up again. Just like before, it ran for about 20 minutes then died again. I jumpered terminals A and B together to check for codes. I had the usual code 12. And I had code 15 for a bad coolant sensor. I replaced the coolant sensor and restarted the truck again. After 20 minutes it started sputtering and died. Checked for codes again and nothing showed up. It wouldn't restart until it completely cooled off.
Any ideas?
