Does Anyone Know If There Is A Way Of Testing The Fuel Pump?
Or A Valve In The Engine Comparment?

I Keep Getting Error P0231 Fuel Pump Feedback Circut Low Voltage. I Replaced The Fuel Pump Relay.the Code Is Still Current
After Being Cleared.
Also C1738:exhaust Solenid Valve Short To Ground
Does Anyone Have A Idea In Which Direction I Should Go?



Any Help Or Advice Would Be
Great!!!

Without having an FSM, your gonna need to test something on teh actual pump.....

Usually, on a Q, when the pump starts getting noisy, then its going bad.......
