This is late being sent, because I was having trouble getting my wireless connection to work. Art, Sorry this has been so difficult for you, and so unrewarding so far, but I get the impression that you're going about this in the right way, and that you're persistent enough that you'll eventually succeed. Don't worry, we'll stick with you thru this to the end.

If the pump runs when you ground the white wire at the left front of the engine compartment, then you have shown that the pump, the pump relay, and all the pump wiring forward of that grounding point are in good working order, so that's good news that you can cross those things off your list. Now, when you get in the car and turn the key ON, do you hear a relay click? There should be 2 clicks, about 1 second apart, but I'm pretty sure you won't be hearing the second one (which is the fuel pump relay.) If you don't hear the first click, check the main FI power relay under the back seat, behind the driver's side. It's screwed to the top of the kick plate. There will be two relays there, the FI relay is the one with the brown ground wire also captured under its mounting screw. Make sure that screw is tight, so that the wire is getting a good ground. Make sure the red wire from the battery + terminal to that relay is good and well attached at the battery. If the main power relay still doesn't work, check to see that there is a wire to it that gets power when you turn the key ON. If not, chase down that wire and find out why the power isn't getting thru. It should get power from the ignition switch. Once the main power relay works, if the pump relay still doesn't work check the power and ground wires to the brain. There are TWO power wires from the main power relay to the brain; they must BOTH be intact. Check the ends at the main power relay, as well as the engine compartment ends at the left front of the engine compartment. Make sure nothing has broken. The brain gets its ground from a wire that goes to the center of the engine case. There will be several wires connected to ground; I believe that on a '71 there will be a 3-lug ground connector on the breather base as well as a single lug connector along the center case seam. Make sure they are all good. I believe there are about 7 wires total which connect to these 4 lugs. They all need to be good. With the key ON, go to the engine compartment and push the throttle down. You should hear a series of clicks. If you hear the clicks then you know that the brain is getting power and ground. If you hear the clicks, but the fuel pump is still not getting energized, then I THINK the only possible explanation is that there is a problem within the brain itself. If that's the case, you need a 311 D brain. I can send you a loaner to try and buy if you choose. Another thing you can try would be to see if the car will start if you run the pump just by grounding that wire in the engine compartment. Run thru these tests as far as you can, then let us know where you get stymied. > Any help will be appreciated as I have found no one in Mobile, Al. area to be > of any help on a FI system.

We're considering several different locations for the '08 Invasion. Any of you out there who thinks you could host a good Invasion should think seriously about what you could do in your area and what kinds of facilities you could come up with. We would like to set the next one up in a different location from past years to let a different subgroup of our listees get in on the fun. The midwest is high on the list, but the south is not out of the question. The US, west coast and the NE states are probably not in the running this next time around. There will probably be lots of talk on this subject in the months to come, but we'll need to make a decision within the next year to give everyone time to make plans. I hope that in addition to attracting people from the nearby area we could also get at least a few people from more distant areas to make a medium sized trip to a central location. -- **************************************** Jim Adney Madison, Wisc., USA **************************************** ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
