Vehicle starts all the time on cool days and evenings, when left in the sun, it cranks but no start. Have determined it to be a no fuel condition. If shift lever is put in drive, you can hear the fuel pump activate, Is this possibly related to the neutral safety switch? I have already replaced the fuel pump relay, and confirmed the pump to be serviceable. Any Honda techs out there that have run into this problem before, I'd sure appreciate a word from you on a cause for this condition and what you did to fix it.
