Check battery cables some times they will draw acid into them and corode and will build residence in them .Have had that problem before

This may sound like a stupid question, but have you tried starting the engine WITH THE DRIVE BELT DISCONNECTED? I have read several posts about a concern similar to yours, that ended up being a seized A/C compressor preventing the engine from turning over. The next thing to try would be to get your 18mm wrench on any one of the four crank pulley bolts to see if the engine will turn over by hand before you start to "shotgun" more unecessary parts at it.

I wouldn't of put new batteries and starter on it if they tested good. I can't stand throwing parts a car anymore... waste of money. Good diagnostic work will save lots of money and fix the problem.

Check the battery cables as stated above. Check to see the starter solenoid is getting switched 12V upon "crank". And yes... check the a/c compressor issue. good luck bud. let us know what fixed it.

after taking apart i went ahead and removed fender well and hopefully it will go back together easier with it out of the way...
