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?

Interesting, but it's fine, connector no connector, it doesn't bother me. Electrically it will all be the same at the end. Leave it as is, just take a picture of the ignition side and tell me what you have for lose wires. With the way it's setup, is there a jumper on the relay from 88y to 88z?

Leave it as is, just take a picture of the ignition side and tell me what you have for lose wires. With the way it's setup, is there a jumper on the relay from 88y to 88z? Just tested the wires that were originally hooked up to the fuel pump -relay and AFM disconnected, got zero volts with ignition off, 12 volts with ignition on. Looks to me that the pump was re-wired through the ignition switch. Never answered your question about whether or not it was running to begin with. The answer is Yes, but very badly. Found lots of gas in with the oil in the crankcase, even blew into the exhaust which would smoke heavily once it got hot. All four plugs wet with gas and a little carbon, but not crusty as if burning oil. Back to the relay. On the ignition side I have a wire from the battery positive terminal that I can connect to 88z and it has the jumper on it that I can connect to 88y. Just took pictures of the relay and need to upload them onto the computer and post them. Just a note, the way it was originally wired, there was no wire hooked up from 86 to the fuel pump. In fact there was no wire leaving the ignition side of the relay and going to the pump at all. I'll send you the pics. |
