My fuel pump was running continuously with the key in the "on" position, so I found the old thread dealing with wiring the dual relay properly and testing the Air Flow Sensor and followed the diagnostics and testing stated in there. Air Flow Sensor tested fine, wiring as specified, and now the pump runs with no key in the ignition. I think the pump was re-wired to run through the ignition switch, which I know was wrong. Now I think I may have a bad ignition side on the dual relay. The relay has two numbers on it. Ignition side says 071 906 059. The FI side says 0332 514 129. All connectors are designated on the relay with the same numbers in the same positions as the 120 that the old thread used. The old thread was great to follow as long as things went as planned. In this case, the result was a failure to operate correctly once all the wiring was reconfigured. Any help out there?

Much more sense! So the fuel pump has a new wire going to 88d. To recap, with the ignition to the on position, the fuel pump runs. Let's check for voltage at pin 86a with the ignition switch at the "on" position. You should have 0 volts present. If you have 0 volts at 86a, then remove the dual relay and ohm out pin 88y to 88d, you should have infinite resistance.
