911 will not start good
 

i hav a 1988 911 sc. after leting it sit for about 30 min after driving it. it will take me 4 or 5 long terns to get it started.
have you had this problem?
what was the problem?

I am assuming you mean a 1988 carrera? The SC stopped production in 1983.

Possible culprits are the reference sensors, or the DME relay.

1980 911sc

Well then I would definitely look at the fuel accumulator.
