Ok, the fuel pressure is good. It should be 56 to 63 lbs. But did you do a fuel bleed down test? You hook up the fuel pressure gauge on the Schrader Valve, cycle the key on, off until the fuel pressure builds up then turn the key off. You watch the gauge to see if it drops more than 5 lbs in 3 minutes. If it does, there is still a problem with the injection system leaking. One other thing to check is if there is power to the injectors.
