Today I go to start my truck, it turned over really slow, finally started, but the gauges ticking and took 5-10 seconds to start working. This now has happened 4 times today. Battery is new and has checked out as good.

Could it be the starter? any ideas?

 

Eventhough you say the battery is new and has checked out ok it still could be a bad battery.....I've seen them puke after thirty days.....

Check your connections and terminals and get the battery load tested again....

 

battery has been load tested, checks out

 

king rancher I'm having the same problem with mine. did you ever figure out what the problem was? I had my battery checked and they said it was fine

 

Have you cleaned ALL the negative grounds? Check the two on the firewall by the ECM.

Especially the one from the engine block and the one from the frame.
