Going to have to second that, always start by trying to replace one part, then see if that fixes the problem, before adding others. I'd definitely remove the fuel pak.
What plugs/wires did you use when you replaced? The newer motors have a reputation for being finicky when it comes to the plugs and wires - many have reported throwing a code and misfiring with aftermarket options.
You've got the right idea by checking anything that you could've knocked loose or broken during the fluid change. Retrace your steps, and keep us posted on any changes. Lot's of knowledge on these boards.

Yes i did replace one thing at a time! 1st i switched my spark plus to see if it moved cylinders, then i put my old ones back in to rule out gap or fouling, then i replaced the plug wires ( taylor/sumax thundervlot). Then my fuelpak came in, i put that in, then i got my coil in, i put that in. all where individual steps.... I am going to clean and check all wires @ my voltage regulater and the CPS. i visually looked at the CPS last night it did not look damaged or distured where it mounts to motor.. thanks for you help guys! i will keep ya updated and anymore ideas is greatly appriciated!! the troubleshooting goes on

This is meant to be helpful, not as lecturing.
Never replace electrical parts if you have not verified if they are bad. Here's why:
1. Spending money needlessly
2. You could get a bad part and still believe you have a problem when it was what you just replaced
3. If you haven't determined the cause of the problem, you could ruin the new part you are replacing by connecting it to a bad circuit
4. If you are not taking the time to find the real issue, you are probably not experienced with electrical problems, you could possibly cause further damage by making a bad connection
This is Electrical Troubleshooting 101, don't shoot yourself in the foot trying to cure what could be a very simple fix if you follow test procedures.

You may wish to pay a dealer or independent Harley shop the $90 for one hour's worth of diagnostics. Once you know what the problem is, you can take the bike back and buy the parts yourself and fix it yourself. Whether car or motorcycle, electrical problems are very hard to diagnose if you are not trained in diagnosing them. And, it may not be electrical at all. It will be worth one hour's labor in my opinion. And that advice is from someone who doesn't have much money either.
With what you have said. I',m with Rondes. You need someone who has worked on a few bikes to look at this. If it has stayed consistent with replacing the plug wires and swapping the plugs from front to rear makes you think fuel system. Sounds like you have already spent more the $90 of your own time. Based on what you said about six month old fuel and having the front cylinder shut down and the codes it throwing you may have a clogged injector on front cylinder. Easy to get varnish and gum after leaving fuel sit that long. Check this link for some good troubleshooting advice and how to clear out the codes. You could have caused some of the codes you are getting while troubleshooting.

plug wires are a week old. does same thing with new and old wires.
the fuel like in about 6 months old it should be fine....but it is only effect the one (front cylender), oil levels are fine. injector wires could be true. it is just weird how Consistant the pattern is....i dont know what codes it throws i need to find a computer to hook it up to!
P0264 Rear Injector High EFI
P0374 CKP Sensor Not Detected Carb
P0374 CKP Sensor Sync Error EFI
P1352 Front Ignition Coil High/Shorted Carb
P1352 Front Ignition Coil High/Shorted EFI
it threw these codes at me! the last one seems like its the issue im encountering since i already seemed to isolate it to that front cylinder.
i just don't know what to look for now from here? wiering loose or pinched? idk
i did remove my voltage regulator and all the wire harness when i pulled my oil filter

All 3 codes could cause the problem you are experiencing. Except you say it is the front cylinder so rear Injector code is suspect and you replaced the coil so that code could be suspect as well, barring a coil driver in the ECM. Just looking at this you could "assume" a problem with the ckp sensor except 0374 the bike should not start??? Are you sure it is the front cylinder misfiring? You could have inadvertently set one or all the codes while swaping parts, etc.
Clear the codes start and as soon as it sets the check engine light recheck for codes.
