So the car will start when the outside temp is hot but if it has sat overnight in the morning it won't start, in the afternoon it will. I know the solenoid is not getting power at the s connection on the solenoid. I tested the starter cut relay and swapped with known good one I changed the starter OEM acura, and replaced the ignition switch, but I am getting the same problem as before no power at the s connection on the solenoid I have continuity on my wires under my dash. I also have continuity on the clutch safety switch as well so I don't think it is that
The car was recently at the body shop a lower ball joint failed and they needed to take the dash out to weld in a new panel before the car went to the shop there were no issues.
I am really at a loss unless there is another relay that could be blown but I have tested all of them and inspected every fuse grounds all look good inside and under the good.
Hope someone can help or has had the same issue and point me in he right direction.

 

Is the positive battery terminal corroded?

Otherwise, about the only think you haven't checked are the underhood fuses 22 (120A) and 23 (50A).

 

I figured it out, the Lt. Green wire coming off the clutch interlock switch is loose going into the MICU (the grey box that has fuses and relays on it next to your left foot), probably happened when the body shop took the dash and MICU out to weld in a rocker panel.

If it keeps on being intermittent I will have to take it back to the body shop and explain to them what I found and hopefully they will fix it if not I will have to find a creative way to fix that 1 pin in the harness.

 

Here is a look at what I am talking about.

 

Glad I could help.
