Injector pump pressure?
As some of you have read I`m having fuel issues.I`m considering the FASS system but want to make sure I need an injector pump so I can buy both.I already replaced the lift pump with a stock pump.I`ve been getting code P0216 the "DEATH CODE".I just picked up a high pressure meter that you connect to the battery and the fuel pressure signal wire.It converts the resistance to give you your high pressure readings.I`m getting 10,500psi most of the time but then it bounces down as far as 5000psi.WHAT SHOULD THE PRESSURE BE coming out of the high pressure side.I heard it can be as high as 20,000psi.This is an`02 5.9L Cummins

Defective VP44 Engine Codes
The retrieval of codes does not constitute an engine diagnosis. However, there are some codes that usually indicate a defective injection pump. A current P1688 always means that the pump is bad, there is no further diagnosis required. Code P0216 is probably the most common code for VP-44 Pumps. If transfer pump pressure has been checked and is O.K., the injection pump is defective. Other codes that are less common are P0180, P0181, P0215, P0251, P0252, P0253, P0254, P0370, P1287, P1689 and P1690. These codes USUALLY, but not always indicate a defective pump. There are wiring and power checks to be performed if these codes are present. These codes relate to Dodge pickups only, and are not for any other ISB application.
