Wow not sure what you needed to hack the end of the plunger off for.
Pull it out with a pair of pliers, along with the spring behind it. This will allow fuel to the injectors, and eliminate this as an ignition problem. The plunger is compression seal on the body of the pump, and this is all relatively low pressure <150psi at this connection unlike the HP side of the pump that the fuel drops into (the rubber plunger simply slops the fuel being able to drop into the piston cylinder side of the HP pump).
If you have fuel in the pump, and is primed well, you have no solenoid plunger installed, then there must be an issue with the pump itself, possibly something has snapped inside? I would definitely do some further investigating on the other points first though before jumping to conclusions because these pumps simply never fail just like that without a hint of issue . . . . . the aim being to get fuel through to the injector lines.
