Intermittent sluggish start.

My 2016 just starting turning over slow. No rhyme or reason. One time slow turnover. Next time it turns over fine. Voltage meter in the truck stays the same and once it starts, everything is fine.

 

First check battery connections are good/tight. Then check battery voltage, with handheld meter, preferably after sitting overnight, must be at least 12.7 for 'fast' turnovers. If those are OK then is on to other things. Let us know what you find.

 

Thank you. I will start with connection. The negative one has a bit of corrosion on it.

 

That is a result of the battery leaking. You don't want that corrosion working its way through the cable.

 

So I cleaned up the terminals really well. Still the truck almost doesn't start. Real slow turning over. New problem also. It's idling at around 500 rpms and my average fuel gauge readout went from 13.1 and is still going down. It reached 9.3 before I turned it off. Could it still be a battery issue? It has plenty of acceleration. I have no idea what the hell is going on. Lol
