Tried to start my truck warm. Would turn over fast, and gauges "danced" around. Eventullay started on third try. Can not get any codes, or to act up again. Any advice?

2000 3.0L 4x4

 

gauges "dancing around" reads like electrical problem.

Check and clean battery terminals.
When cranking engine voltage in system drops down to 10volts if battery connections are good, it can drop more if they are not good and that can cause gauges to act up and computer to shut down so "no start"

 

Found alot of "baking soda" looking corrosion, on battery terminals.
I'll clean them off, and check charging system. Found a bad regulator will cause overcharging, to make that type of corrosion.

thanx!

 

replaced battery terminals, and checked battery/charging system. No problems, until today. Did same thing again! Only acts up when cut truck off, and IMMEDIATLEY try to re-start. DTC 125
