I had the same problem yrs ago when I bought my Talon...Just wouldn't start when hot...I would have to let it sit for 20 mins or so every time...

The problem that I was told was the fuel pump or something to do with it...I took it back to where I had purchased it and they fixed the problem...I don't know how though as it didn't appear as they had replaced the pump (bolts still dirty etc.).

Now when hot, my car starts but wants to stall...This goes on for about 30 secs or so...

I'm just saying that you shouldn't write off your ECU yet...Check the fuel system first..

Hope that's a lil help...
