cold engine start oke hot engine no start
 

i have a 928 gts 1993

my problems is that the engine (cold start whit no problem)
when the engine is hot (no start possible)
help me

is the battery dead,
does it have gas,
is the airfilter plugged,
have you swapped out the fuel pump fuse,
have you replaced the 4 relays for the engine computer ignition system,
Have you pulled the vacuum lines off the dampers and FPR to smell for gas,
What was the last thing you fixed,
did you just wash the car,
have you cleaned the grounds.

FWIW if you can be more descriptive about what is happening when you turn on the key it will lead to a more precise diagnosis
