Can anyone help me with the following.
I am getting a message "fueling failure" I have checked Fuel relay, Main Relay, Fuel Pump (on rear cross beam)

What happens is the car at times will not start, sounds totally dead. Found out that if I disconnect the main fuel supply pipe after the pressure reducer, allow the fuel pump to pump a half coffee can amount of gas, I can rejoin fuel pipe and car will start, also found if I disconnect the vacuum pipe from the fuel return pressure servo, the car idles better. Could this be a faulty fuel pump (not producing enough pressure) or bad return fuel pressure servo
