For some reason my truck doesnt start some of the time. The battery is only 3 months old, the interior lights come on, but the truck will not try and crank or anything. This only happens some times. I will hop in my truck in the morning, go to my first job and it will start fine, but then I leave for my second job, it wont start. Then if you leave it alone for a while it will start. Today I got mad at it and kept cranking and hit the brake a few times and it started. Any clue what this could be?

 

what is your battery reading? are your terminal posts clean?

 

Have not went in to see what my battery is at, and the terminals are clean

 

when you try to start it and it doesnt start do the interior lights dimm heavily

 

No, the lights dont dim

 

possible short in the ignition? or a loose wire. when the truck does start is it a strong start?

 

Ya it starts strong, no hesitation when it does start.

 

something could be wrong in the ignition circuit. possibly a loose wire? you dont hear the starter at all when you try to start it?

 

No starter, no nothing. How would I check the ignition wires, am I gonna have to pull the whole dash out?

 

When it acts up again, try switching the starter relay with another one in the junction box.
