the only pressure is in the fuel rails,and it gets as high as 23000psi. Does it run? Because if its only getting 100psi the injection pump is bad i would assume because i don't think it would even start with only 100psi.

The fuel system is under a vaccuum (up to the injector CP3) unless you have a lift pump.
