2001 Acura CLS 130k miles Have starting problem whem tempature is 85+ on some days. Let car sit for several hours, starts right up. This has been going on for 14-18 months.My issue: took car to local Acura dealer, explained problem, his reply "can only check out when car inno-start mode. My luck I would have it towed to dealership and car would start. Anysuggestions?

I have had the same problem. Parked in the sun, would not start. Opened
the windows nad after about an hour, it would start. It was the main
relay. It was explained to me that the solder connections go bad. I
removed old solder and resoldered and all was well until recently. I
thought it was main relay again, so I bought a new one. Not the
problem. My car just dies at random times. I think the fuel pump is the
problem. But yours sounds like the main relay.
