Thanks yall by the for the help on how to diagnose the FPR (Fuel Pressure Regulator) that was going out on me. Well the problem is still there. I also replaced the fuel filter at the same time because it was about time for a new one anyways. So I am turning to yall again for more ideas about this. As it stands right now It has a new Air Filter, Injectors, FPR and Fuel Filter. I also had the Battery, Alternator and Starter checked again for the third time and they are still good. Also I put about 30 miles on the new FPR and fuel filter and it hasn't made and difference on my starting problem. Still after 6 or 7 hours it take a few minutes to start but after that it will start every time. Also the gas smell I was getting in the vacuum line from the FPR and the exhaust went away after I replaced it. But I am wondering what else it could be. Could it be my ignition Switch or my Ignition Lock Cylinder/Assembly or maybe it could be my fuel pump. So any and all advice will be helpful in this follow up question. Thanks.

Also I replaced the ignition coil pack and the wires earlier the year to. I added new spark plugs also when I replaced the injectors. So most of the ignition system and fuel system has been replaced.
