I'll be running clean fuel through the pump and watching the output to make sure it's clean.

Good luck. You're not "f-n retard" it's easy to over look these things. The part that bothers me is that you said you didn't have spark, which will be a completely separate issue. Check your injectors like you said, but there's a good chance the filter stopped the flake before it reached the injectors. The screen on the pump will need to be replaced and possibly the pump as well. If you continue to lack spark, test power/ground to the coil, if none, were right back to the crank/cam sensor. One handles fuel, the other spark. Good luck.

I know this is probably WAY out in left field, but since he did mention a temporary loss of spark, maybe while he had the tank off some of the electrical connectors got tugged on. He might want to pull them apart to double check them (and put some anti-oxidizer in there) then pop them back together and see what happens. Just a thought.

I could be wrong, but I don't believe any electrical connectors related to the ignition system run under there. If they weren't properly grounded while out like he mentioned, then that would make sense. As far as the fuel pump, yes definitely check pressure, but also inspect the pump. There should be a filter element at the bottom, which could be clogged. Not sure if the fuel filter is down stream or up stream to your pump, but if flake made its way to the filter, it's more than likely in the pump.

thats news to me. I've never tried it but I thought you could remove the plug to test spark. Guess he's gonna have to get a spark tester. I thought he already stated he did it once and had spark though.

All Delphi system HD bikes are that way.. Try it sometimes.. You hold your thumb over the rear plug hole to see the motor make the spark.. The ECM uses crank slowing on compression to ID which cylinder is coming up on the compression stroke..

Update
Well gents, road dogs, scally wags and or fine people; I want to thank each and every one of you that offered tips and advice. I have lit a match and dropped it in the gas tank and am watching the bitch burn.
HA. I'm thrilled beyond words. Bitch is fixed and running for the time being at least and hopefully for good.
So what was the problem, you might ask. Ok so I found the pressure regulator spraying fuel in the tank. Was advised it shouldn't do that and the filter was terribly clogged. Cleaned inside of tank real good again. Replaced regulator, fuel pump sock and filter. Got same result from regulator and of course ***** still wouldn't fire up. Pulled injectors, left hooked up and found no spray. Removed injectors, sprayed with carb cleaner, let sit over night with cleaner in injectors, sitting on work bench. Called Harley and was informed in fact the regulator should spray on initial prime while pump is cycling ready for start. Got home, hooked injectors up and checked for spray. Holy hell they squirted fuel. Reinstalled, cranked her over and vroom f-n vroom it fired up. Put tank all back together, put a gallon of gas with BG 44K fuel treatment in. She started 6 times no issues. Gonna let her sit for couple hours and see if she can manage to repeat the performance. Maybe, just maybe I'll actually get to ride these next couple 70+ degree days.
