91 honda accord around 120,000miles and changed many parts but can't figure out whats wrong and why it won't start, sometimes I can open the gas lid for a bid and it might start but its a hit or miss considering how hot it is outside. Any help anyone???

 

the gas could be turning into vapor in the fuel lines, and it won't start, and is a common thing when hot

 

If that is the problem, i would look at the fuel pressure regulator.

 

Fuel injector Main relay, had the same problem on my accord, the more humid and hot it was, the longer I had to wait
