Saturn - Ion :: 2003 - Hard To Start After Sitting Long

I have a 2003 Saturn Ion-3 that I bought a few months ago. It has 157,000 mile and runs great when it will start. Here is the issue: after the car has sat for several hours it seems to flood and starts hard. I end up putting the accelerator to the floor and this seems to work. I have to crank the engine repeatedly and when it catches I hold it to the floor until the engine clears (lots of chugging and white/blue smoke until it clears) and then runs just fine. If the car sits for a short period, it starts ok. The longer it sits, the harder it is to start (i.e overnight or a whole shift at work).

If the car sits for several days it starts just fine. It acts as if it floods while it sits so I changed the Coolant Temp Sensor, still acted up. I then checked the fuel pressure at the schrader valve (55 psi) and noticed that it lost pressure as it sat. I assumed that the injectors were leaking and had them rebuilt (by Mr Injector). The flow bench results did not show and leaking. I reinstalled them along with new spark plugs and the car started up immediately and ran/drove great. This morning was the first morning of sitting all night and it would not start again. It tries to fire but will not catch. I tired to have the CEL code read at autozone but they told me my lighter wasn't working and the couldn't do it (although it runs my GPS just fine).
