Default Spuractic starting problems still going on after I have replace so much

I have been getting long crank times or short crank time on trying to get the car to kick over. It varies from day to day. One day I can barely bump the key and it will start and the next day it will take all most a minute or so to get it to start. I can hear the starter engaging but it won't fire over. I have replaced the Starter, Alternator, Battery, Coil Pack and the ignition switch. I had all the stuff rechecked and it comes out fine. Also I have replace the Fuel Injectors and the Fuel Pressure Regulator. So since winter is creeping up I am wondering if my problem may be my ICM (ignition control module) is acting up. Also if it may be something else would it still be a good idea to get an ICM from the Junk Yard for 20 bucks. Also yall have helped me allot on my older car so I am throwing this one back out again to yall. Does this sound like an ICM problem or maybe something else. Thanks.

Also when the car finally kicks over I can smell fuel for a bit and it has a shake to it. Also I cleaned the IACV sensor. ( Idle Air Control Valve) It helped the car out a little bit on the hard starting and a random dying problem it did have. But it didn't fix it.

You will need to determine if the problem is fuel or spark. Start with this. Turn the key to run, wait a moment, then start it. If it works fine then your loosing fuel pressure when the car is sitting.
