Here it is. But I warn you that any testing you have in mind should only be POSITIVE & NEGATIVE. Anything else could destroy the ECM.

Hi Maj. Dundee,

Great links for electrical. I have the same vehicle and wondering if you know which connector coming out of the ECU provides power to the fuel pump? I have no voltage at the fuel pump and all 3 wires there are in continuity with ground, so obvious short to ground somewhere. I cannot tell from the WHIP drawings which circuit goes to the fuel pump.

Thanks,

Mark
