Hard Starting! Fuel System Diagnosis - Pump? Filter? Regulator? Olds Silhouette GM 3.4L V6

In this video we attempt to analyze an occasional hard-starting issue likely due to insufficient fuel pressure on a 2000 Oldsmobile Silhouette minivan with a 3.4L V6 engine and a PFI fuel system. We'll learn: How to connect a fuel pressure gauge to the fuel rail. How to measure fuel pressure Key-On-Engine-Off and Key-On-Engine-Running. How to compare actual fuel pressures to factory specifications. How to use a multi-meter (ammeter) to measure fuel pump current draw. How to install a section of rubber hose in order to clamp off the return line. How to use a compression connector to repair the plastic fuel line. How to replace a fuel pressure regulator. In the end I conclude that I have a weak fuel pump. This diagnosis was tricky because the pump did not die, but simply was weak.
