Question
how do you know if injector pump is bad

Answer
First you have to make sure you have fuel to the pump. If you have fuel to the pump then you have to crack the injectors. Crank the engine over and see if fuel comes out of the injector lines. If it does then it might be your injectors or compression on your engine.
