I know you said it's not the battery, but did you check the battery to completely rule it out.
Sounds like a bad battery to me? lights will come on even if it has a low charge, but wont turn over.
Batteries can act so weird when there bad
Good luck

OK, what happened? Did the OP find an answer?

My 2008 LT (2.2L, automatic) did the same thing today after I got to work this morning, started perfectly after a couple hours, then never started again and I had to leave it at work to look at tomorrow.

Tomorrow, I will be checking the battery (still the 2008 original), grounds, and whatever else I find on here for ideas tonight.

So, if this thread had a happy ending, can somebody share?!?

 

Yes i did check the battery. I hooked another battery up to it and still having the same issue..

 

I still have not found the answer. I am currently trying to trace wires to see if there a broken or loose one somewhere.. if u find something out PLEASE let me know. I would appreciate any ideas and help i could get at this moment..

 

How about checking the connection at the under hood fuse box. If loose or has a poor connection it can't make an intermittent no crank condition.

 

I have checked that but i will check again

 

Is the problem still intermittent?

 

No it hasnt started in over a month... been sitting in my driveway and i been driving my wife van. Dont have money to take it to a shop so i have to do everything myself.

 

Why do you resist looking at the starter solenoid and the starter ground? It is also possible the key switch is bad.

 

I have replaced the starter and checked all the wired on the starter. I have replaced the ignition switch and reprogrammed the key still same issue
