I just bought a new battery and had 4 k gsk put in truck was running great quick start everything great it sat for 6 days cause I had to work and tried starting it grid heater warmed up fine then I try to turn over I just get one solid click then nothing any help would be great thanks

 

Batteries still charged? Try jumping it or putting a charger on them?

Think it's just time for a new starter any way to check thanks

 

Try giving the starter a couple taps with a hammer.

 

I beat the hell outta it just that one click then nothing I was told to check tot see if I got power going to it would I just take a volt meter and put one on the positive wire under the starter and ground the other to the block again all replays appreciated

 

Might just be the starter solenoid contacts all burned up. The starters themselves are pretty beefy, but, the OEM solenoid contacts are kind of smallish for carrying the sudden burst of current needed for kicking the Killer B into life. google up "Larry B's starter contacts". I've had a set in for probably 8 years, before the starter itself suffered a broken mount and had to be replaced. I installed new contacts on that one before the install, and have had no problems.

 

Yea I had seen that on another post does anyone have the fuse box diagram mines Mia and idk what fuse is the starters

 

try your batery cables mine seem to do that everyonce in a while they get loose.. try cleaning them and tightening them again... mostly happens to my ground on driver side..
