Crank no start

A ton of stuff could be wrong.
Igntion coil, crank sensor, fuel delivery. Throttle posistion sensor maybe to
Does it have spark? I was running poorly. Does it start at all now?
Couldn't test there, but after going through things at the house im leaning towards no (at the time). It starts and idles great now, and did so immediately after coming off the tow truck.
My 07 would stall once in awhile when under half tank. I had 55k miles, so I replaced pump, hoses and filter. Because it ran fine over 1/2 tank I knew it fuel. Plus at 55k, I figured good to just replace all that stuff. I could not find any holes by just blowing on lines, but that is not very accurate either.
Just repalced the coil on 01 for second time. But my 07 is still working. Should one of these days.
What about codes? You can read through dash with kill switch off. Hold reset button in, and turn on bike.
check engine should come on during start up, then turn off. If recent code will come on again. If active code will stay one, I believe. I woiuld check codes. Though on my carbed bikes it didn't crank and cpk were bad. But still worth looking.

Just another thought, was riding the other day in 100* heat, bike didn't die then, but when i tried to take it to 4krpm it was missing like crazy. Heat related again.
read through the cns diagnostic tree in the manual and im leaning hard on the coil

2007 lowrider.
More details as my sfb remembers. About 6 months ago i had fuel issues and had to replace the pickup, filter, and regulator, but stupidly didn't replace pump or lines.
Ive also replaced the o-rings on the tank quick connect line (but ive read the safety in there can be a hot start issue so maybe replace that pos).
Soo, after much reading, maybe vapor lock caused by pinholes the line? (But fuel pressure cold here at the house is 60psi, only bleeds down to 55psi if i wait to crank it), it will crank up now cold and fuel pressure will hold steady at 60psi.

No such thing as vapor lock when you have 60 PSI.. It's not a problem for the pressure to drop slightly in the first pressurization.
