Long story short, i pulled my motor to re-do the oil pan and a bunch of other stuff. I replaced the CPS since it was out. All fuses check ok, fuel heater, hpop reservoir etc.. all look fine. The tach will not move. I have tried two new CPS"s so I am ruling that out. What else would cause the tach not to move while cranking? I have no exhaust smoke, so the injectors aren't firing. IPR was rebuilt as well. IM confused.
