well I've got a starting problem with my truck i just did a 6.0 swap heads cam 11.1 compression I'm pretty sure its the starter getting heat soaked. if the truck sits for about 30mins it starts no problem.

i did do a battery relocation in the bed but i made sure all the grounds were good and the battery is new also the starter is new.

any ideas how to fix this problem its getting old

 

Is it a slow crank? Do all the trucks use the same starter? Maybe something off an LS2 would work better if they dont.

 

yup it cranks like the battery is goin dead but its definitely not the battery i think its the starter getting to hot.

from what I've read all the LS style starters are same I'm thinking i might just do a power master high torque gear reduction one.

 

Thats interesting... I wonder why its getting so hot? Does it crank slow when its dead cold??

 

There was another guy that had this same problem. I think it was "bumpers" or something like that. I'm not sure if he found a fix, maybe he will chime in.

 

nope fires right up no problem
hmm ill look and see if i can find his thread on it
