Which car is this on, UrQ or 5kq? My first bet is the check valve at the fuel pump.

> The Symptoms:
> When cold, car starts immediately upon cranking. Runs great with no issues.
> Idle is strong and steady at 850 rpm.
> Hot Starts:
> When attempting a hot start, after the car has been sitting for a few
> minutes, it immediately catches, stumbles, then stalls. Car will continue
> cranking with good spark, but there appears to be some vapor lock or
> flooding-not sure. No strong smell of gas at all.
> What's Been Done:
> -New 85 deg C injector cooling fan thermo switch. Injector cooling fan
> works fine
> -New vacuum thermo switch (the one on the block near the ig distributor
> -Checked for vacuum leaks-none found
> What should I pursue next? I was leaning towards fuel pump check valve,
> then injectors. Does this make sense? I don't believe that there are any
> vacuum leaks, however, I will keep checking this as well.
> Thoughts, suggestions, please?
