Hi,

Even though you are getting fuel out of the filter does not mean the pump is providing sufficient pressure. I attached the documents that you will need to properly test the system. It includes the spec for the pressure for your engine.

Also, here is a guide that will help you test the pump:

Once we know the pressure is the proper amount, we can go to the next step. Not only does this tell us the pump is okay, but it tells us if the fuel is getting to the rail. If so, we can suspect the regulator is the most likely issue.

Let me know what the fuel pressure is and we can go from there. Thanks
