Here's a quick video of what I'm seeing when the fuel pump primes - gas sprays around inside the tank. I've read on some forums that might be normal since the lines are pressurized, the priming pushes gas back into the tank through a bypass.
Guess I'm stuck without that cam tool to remove the top plate. Maybe it's time to call for a tow.

OK, here's something - or maybe a wild goose chase. I checked the system for codes and got a P0374 CKP Sensor Synch Error. It suggests Part No. 32933-08, which doesn't seem to exist. I'm checking now to see if there is a way to check the crank sensor.
But if I'm getting an intermittant spark while cranking, wouldn't this mean that the crank position sensor is working???

Change your filter and the two lines. Don't buy Harley Crap. Go to Napa and buy submersible fuel line. You need 3' of it and it only comes in a 1' or 10' roll. Buy the 10'. Up here it was 30 bux. You should not have fuel spraying inside the tank. You will have to grind the clamp a bit to feed it into the bottom of the tank where it joins the quick connect. Be very careful removing the line from the top of the regulator housing. They break very easily.

Thanks for all the suggestions. I cleared the codes and started over again and it's not throwing any, but of course, nothing has changed. I found this useful service guide, but it may or not apply to my bike. Good troubleshooting flowcharts in it though. Problem is I don't have all that scan equipment, special tools, pressure gauges (or patience or time at this point).
I think it's time to throw in the towel...

Could be fuel delivery issue. Fuel crossover line from quick disconnect at the tank to injectors deteriorated. Not noticeable from a visual inspection.
I believe moco had a service notification on this some time ago.

If it we're mine, I'd go to HD for it all. This is a pressurized system with fitted connections at all points. It's not a gas line/ mini clamp connects. Yes, you'll pay for it but in the end much less trouble for the DIY guy. Just my opinion.

It's damn frustrating to not be able to figure this out, but with the electronics these days, you're blind unless you have the right diagnostic computers or just want to start replacing systems.

I think I would hit the intake with some starting fluid to make double sure you're getting spark at the right time... If it lites off and runs for a few seconds you know your crank position sensor and ECM are synced correctly.
If it runs for a few seconds, the issue is fuel. In that case remove the fuel hose end that feeds the injectors (small screw and blade lock) and point it into a gas can or glass jar. Try to start it and ensure that fuel is pumping.
