Truck has a new injection pump and lift pump. Injectors were replaced last year. New CPS... has fuel to injection pump but very little to injectors. Injector lines to 1, 3, and 4 are cracked open. Number 3 gets a small amount of fuel, numbers 1 and 4 get none. Borrowed a good ECM and still just cranks. The injection pump was tested and it is good. Has a brand new air dog raptor 100 lift pump. Truck has 17 psi to isspro gauge when you turn key on... when cranking it has 12 psi. RPM sits around 250 when cranking. Injection pump has 12.2 volts to connection. Overflow valve is good at 13.5 pounds. Not sure what is causing the problem at this point need help.
