If it's a no-crank situation the whole no-fuel/skinner valve ting is not the issue, so don't worry about that until you have a cranks fine but won't start problem.  My first thought on a no-crank just after running is the fuel pressure interlock switch is hanging open.  That switch is on the rear fuel filter on MCI's (closest to the starter motor) and it removes ground from the starter relay if there is fuel pressure so you can't crank the engine if its running.  You can bypass that switch by simply taking the lead off it's terminal and connecting it to ground.
