Hi, The grounds appear to be ok. There seems to be a pattern forming of when the car is at proper running temp it gives these issues but when it is mildly warm or cool it does not.

 

Do like dannylee suggests and redo the grounds regardless of how they appear. This has resolved many sporadic starting issues on this forum. You need to remove the battery negative to ground connection at the frame. You need to sand the spot well and clean up the connector and reattach with a self tapping screw. Then clean up the connections at the starter. Once you actually try this then if it is still acting up you can move forward. Fixing the connections is a free and easy fix. If that doesn't solve it then it may be a fuel issue (there are several places it can give you trouble), or spark issue. Get back with us and let us know what's going on. Good luck!

 

It worked well for me and it's been over 6 months. I still have that spare starter sitting there for when I do need it.
