The only way this can happen is if the power to the ECU is staying on, and your statement below that you hear the click later, after the key is turned off and at almost exactly the same time as when the engine actually stops, confirms this. The relays should all drop out EXACTLY when you turn the key off. If you ever hear this happen with the ~1 sec delay, then the main relay is hanging up, something I've never seen, but it might happen. There is also the possibility that the relay is wired wrong, so that the ECU is getting power ALL the time. This would make the power relay click, but be irrelevant, and you would find that the fuel pump relay would stay on until !` sec after the engine stopped, which could happen any time after the key went OFF. Somehow, I think I have that relay wired correctly, as I had to add those 2 new white wires to it, remember? I'm curious about when you experience this and then turned the key back ON. Did the engine then run and sound normal, or did you have to actually restart it? What do you mean by "all the way ON again"? > I couldn't hear if the switch was going off what with the engine > turning over.

The generator belt wouldn't cause this, and I don't think a leaky injector would either. The REALLY BIG CLUE here is that you say that the relays did not click off when you turned the key off, but later, when the engine finally stopped. This is telling us that the FI stayed on even after the key was turned off. I'm guessing that your main power relay, under the back seat is sticking occasionally. Russ, have you ever seen this happen? I haven't. I still have your package here. I think I'll add a spare relay to it. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- List info at http://www.vwtype3.org/list or mailto:help@vwtype3.org
