cranking issue

[crxx]

today after going outside to tighten the bolts on my exhaust my 99 tahoe wouldnt crank. all i did was start the engine,drove it up on the ramps,turned it off. I then tightened the bolts(headers), restarted the truck and backed off the ramps and turned the engine off to put my tools away. getting ready to leave and as i turn the key.... nothing! the battery is good,lights and stereo comes on,i can hear the starter relay click on..... but nothing else. its an automatic tranny 4wd. any ideas?

not that i've had any problems, but how does the factory security systems on these things work? i have the keychain door lock/unlock remote and it woks fine. but is that what is referred to as security?

I found out the starter was going bad.....did the tap on the starter trick and it fired right up..... Getting a new one in the morning!

Had that problem with my old 1500 pu! At least ya found it and it's nothing too major.

wish I saw this earlier, happened on both of mine out of no where. I always start with the basics...battery, starter.
