I recently replaced the Fuel pump and filter in my tahoe. Right before the pump went out I got a check engine light and then a few miles later the car stopped. I could not hear the pump when I turned the key and there was no fuel pressure coming out of the check valve. Now that I have replaced the pump I can get the car to start but my fuel pressure only reaches 25 psi and comes up very very slowly. When iIturn the key to the "prime" position I almost get no fuel pressure response at all but i hear the pump engage. Could my fuel pressure regulator be stuck open? I am also getting a system too Lean code on Bank 2. I suspect it just isn't getting any fuel. It take two turns to start the car. It iidles at 1000 for a few seconds then settles on 600 RPM . It doesnt stumble and accelerates fine. What shodu lteh car idle at?
