2006 TB LS 5.3L. I am "pretty sure" that my intermittent no-start condition is due to or related to the PNP safety switch. Symptoms: normally there are no symptoms and the TB starts fine, but say on the 80th start 50 miles down a dirt road next to nowhere, when the key is rotated to ON the dashlights come on, then dashlights go out when turned to START position, no sounds, no clicks, no nothing, then dashlights come back on when the key is returned to the ON position. This is the same thing I experience if I try to start the vehicle in R or D. Battery is new, cables tight, wires to solenoid and starter tight. That is why I am thinking the PNP switch. No codes are stored. So before I go and break something, or wind up not being able to get the new switch back on or adjusted, does anyone have the info to do this properly? I've surfed about various places, incl. Youtube, but I don't get a whole bunch of confidence doing this without asking someone KNOWLEDGEABLE or finding a GM manual or whatever that tells me how to DO CORRECTLY.
PS: I live in Florida and we are going to be towing a 5000 travel trailer to Colorado and beyond, so would prefer to avoid getting stranded.
PSS: This vehicle has been driven to 2 different shops, towed to another, and sure enough starts up fine and "can't be fixed 'cause it ain't broke". Arghhhh.
PSSS: I am going to replace the starter relay as well just because it is $11 and replacement requires skill and intelligence of orangutan which I believe I can muster.
Thanks.
