I have a 2000 ss that has a crank but no start condition. I have checked fuel pressure and it was 58 at key on. somtimes it will start but when you turn off wil just crank. Any ideas? There are no codes!

 

Have you checked to see if it is firing the plugs when you are having a no start condition? Are you noticing if the fuel pump is running when you turn the key on. It may be turning on some times and not at other times.
