Hello. I have a 2001 Acura TL with 250,000 miles. It runs great except for one major problem, it will not restart (but will crank) when the engine Is hot, no matter what the temp is outside. After I drive around and get the engine hot then park for about 30 minutes and try and start it, she sputters and almost wants to fire and then doesn’t. The weird thing is that If I kill it (when hot) then start it immediately, it will start right back up. It is only when it is off for awhile, 10-30 mins when it wont and then I’m just cranking it over with nothing. If I wait about 30 minutes more, it starts up no problem just like it does at the beginning of the day. What happens in those 30 mins or so when the engine is hot and turned off that makes it not want to restart? It’s not the fuel relay, that has been ruled out. I’ve read a few things perhaps EGR, perhaps leaking fuel injectors. Anyone else have this? Thank You

 

Affix a clothespin to the fuel rail.....Sounds weird but it works. The wood absorbs the heat apparently which is the issue you're having. I've been doing it summertime here in Ft. Lauderdale for years.

 

I know fuel pump relays went bad a lot in Hondas of this vintage.

 

Ok, I'll try that. Thanks.

It has a new relay so I know it can't be that.

 

OEM or aftermarket relay? Just because it's new doesn't mean it works.

Can you hear the fuel pump come on momentarily when you switch the key to on?
