1997 Chevy 1500, 5.7L, 4x4, X Cab. 3 year hold AC Delco engine (brand new) This is my first post (and hopefully not my last as this seems like a great forum). I'm having issues with my truck not starting. The first time I had issues was last week. It "clicked" when I turned the key, but does not even attempt to turn over. It's not the battery because I just purchased it a couple of months ago and all the "power" works fine in the vehicle (windows roll up quickly, stereo works, lights come on full brightness). I pulled the starter and took it to a local auto parts store (Auto Zone) to have it tested. It passed and they said it was as if it was a new starter. I had actually replaced it about 2 years ago, so I expected it to work fine, but this confirmed it. I brought the starter home and put it back on the truck and then it started right up. I had figured it was an issue relating to maybe my battery cables not being tight enough. The next morning I went to start it to take it to a muffler shop (I busted the muffler the prior weekend while camping) and it wouldn't start again. I talked to my brother about it and he said to pull the starter again and get a second opinion. I pulled it off today and took it to another parts store (O'Reiley) and got the exact same response as before (it tests just fine; as if it were new). I'm just not sure what to do from here. I've inspected the positive cable from the battery to the starter and it looks just fine. I've checked all the fuses and none of them seem to be blown. Any other suggestions of things to look at before I spend $500 for someone to comb through it? Here is a link to a short video of me trying to start it for anyone wanting to get a view of what's frustrating me. It's acting as if the starter is the problem. Thanks in advanced for considering helping me with this problem.
