Car starts. But with issues

I am reading alot about cars that DON'T start, well mine starts, but with issues. I have been having an overcranking issue for a month or so, but most recently when it does turn over, the engine is only hitting about 2, 3, maybe 400 rpms. It's almost like do I start. Or do I die. I either kick the gas, and it fires up, or shut it off and try again. Once started I still smell gas fumes from the exhaust. This only happens at start up (cold or hot). When it's running it's fine. My gas milage seems to be unchanged and It dosen't stall at stops. I have checked for vaccum leaks, cleaned the IAC valve and the EGR, ran some fuel injection cleaner through, changed the wireset, and checked the plugs. I heard that this could be either the ignition coil packs, fuel pressure regulator, or maybe I do need to replace the IAC. I'm also not sure if it could be another sensor (air temp, crank position, ) etc. Or? Any suggestions would be helpful. Thanks
