I am losing fuel pressure in a bad way.
When I allow it to idle I am looking at 28 psi. When I pull the vacuum line from the regulator it jumps to 35 psi.
I know that is a little low, but my problem is when I give it gas the fuel pressure drops down below 20, I audibly hear a back fire, and the engine nearly dies. When I release the throttle it will jump back up to around 25.
The fuel pressure regulator is new and I recently cleaned the throttle body and upper intake. I also installed new denso plugs, plug wires, rotor, and cap. I will be changing the fuel filter again tomorrow.
Should I just go ahead and get to going after the fuel pump?
