During the winter I didn't have any issues, but now that's its pretty hot out, my hot start issues have returned. When I'm cruising around for a while in hot weather and totally heat soaked, I tend to have a hard time with start ups. Its starts eventually after a couple cranks, but I will eventually get a P0190 FRPS code for fuel rail pressure.
I think what's happening, when its so hot, is that the ethanol is vaporizing. My crank lambda's are VERY rich to help with cold start ups in general, so I don't see how much richer I can make them in this case.
I'm running e85, on a return fuel system with a fore regulator and rails.
Don LaSota's book has a section on hot start problems - I haven't bought the book, was thinking about picking it up, but if anyone has any obvious tips that would be cool. Thanks!
