Hard time starting?
 

My 98 z28 is having a hard time starting... I'll crank it for about 5 seconds, then it'll start, or crank then turn the key back, then will start right up...

Car is stock other then Lid, catback, msd wires, and slp maf...

any ideas on what i can start with?

If you turn it to on (not start) can you hear the fuel pump prime?

Yes

double check the fuel pressure....not sure what its supposed to be at prime and running. :waits for a chime:

see if your fuel filter was ever changed btw. probably not the problem, but it couldn't hurt to change it

Yeah... don't know about that... but you know how it runs otherwise.

If the car is running... say shut off then try to start it 5 minutes later, fires right up.

Sorry for the NOOB questions, but I'm just trying to cover the basics. How old is your battery?

2 Months... It cranks it over just fine.

Sounds like the fuel pressure is bleeding off when the car sits, so it won't fire up until the rails get pressurized again.
