Default Hard starting

I'm pretty sure i know the problem, but not sure whats causing it. The car will crank over for about 5 secounds before it starts if parked for more than 5 minutes.. I rock the key back and forth to activate the fuel pump to build pressure and it fires right up. I cant smell any gas leaks, so its gotta be draining back into the tank.. any ideas?

...
people laugh when they found out i bought a saturn, I laugh when i drive nearly 500 miles on a tank of gas.

REWARD EXCELLENCE!

The only way to confirm your suspicion is to use a fuel pressure gauge on the fuel rail where a test valve is available to check fuel pressures. Bleeding off will be obvious.

Have you checked for the proper engine coolant temperature sensor (ECTS)? Use the Forum Jump below to find the How-to library about the original plastic sensor and the brass replacement. Use the side-by-side profiles to see if yours is the plastic one and if it is replace it from any auto store. The failed sensor can still cause rich running conditions even after a full warm up, causing similar hard starting as opposed to fuel starvation.

It does the same thing if it sits over night. The car otherwise runs absolutely perfect, with no codes to speak of.
