Hi my name is***** will be glad to help. Most common causes for low fuel pressure if no leaks or restrictions are found are a faulty transfer pump or fuel pressure regulator. Fuel pressure should be and maintain around 70-90 PSI consistently. Are there any fault codes?

actually correction, Fuel pressure should not drop below 75 psi. Check with a mechanical guage. Let me know
