1. If pressure is low but greater than 3 psi (indicates fuel pump is running but not enough pressure) check for: o Plugged fuel filter o Kinked fuel line o Low voltage to pump (should be without 0.5 volts of battery voltage at connector). o Disconnect the fuel return line and note if fuel is being returned during this low pressure condition. If fuel is being returned, replace the fuel pressure regulator. Reconnect the fuel return line.
