My Jimmy GMC 2000 has the same problem, I only get 50PSI when i turn the key, when it is started and running the fuel pressure gets lower if i idle it higher. After i shut off the jimmy my fuel pressure slowly goes down to zero on the gauge . I need some help here. Changed the fuel filter, fuel pressure regulator also.
