I have a 2000 Acura Integra LS. My cars been stalling on hot days, thought it was the main relay, replaced with a brand new one but car still stalls. Anybody have an idea what it could be?

 

Any codes? MIL/check-engine light?

 

Nope, no codes. After it died, I checked if it had spark and got nothing. So I bought a B20 distributor, swapped it out with the old one, checked for spark and it checked out ok. Went to start it up, cranks but won't turn over. I'm thinking maybe I flooded it? I'm stumped right now. Gonna do more testing on it tomorrow so I'll keep posted.
