<div dir="ltr">I was simply going by what the Bentley states. That's all I have for<br clear="none">reference. In testing the fuel pump Bentely states not to ground that wire<br clear="none">connected to the ECU it doesn't say all years or specify a year. I never<br clear="none">had any issues with the pump not running except once when it was the<br clear="none">connector on the fuel pump. I have no more advice to offer. The only thing<br clear="none">it seems I was possibly right about was connector T1 and it's an<br clear="none">intermittent electrical issue and only because it did work a few times.<br clear="none">Bypassing the relay 87 to 30 will only tell you if the pump and it's wiring<br clear="none">are working if the engine runs, it won't tell you anything as to why the<br clear="none">pump relay coil has no ground. The Bentley is fine for some things, not for<br clear="none">everything.<br clear="none"><br clear="none"> At least I tried and in doing so made me look like an idiot offering all<br clear="none">the wrong advice.<br clear="none"><br clear="none">On Sun, Jul 11, 2021 at 9:19 PM Jim Adney <<a rel="nofollow noopener noreferrer" shape="rect" ymailto="mailto:jadney@vwtype3.org" target="_blank" href="mailto:jadney@vwtype3.org">jadney@vwtype3.org</a>> wrote:<br clear="none"><br clear="none">> On 11 Jul 2021 at 17:17, William Jahn wrote:<br clear="none">><br clear="none">> > If you just ground it connected you will kill the ECU.<br clear="none">><br clear="none">> No it won't.
