Latest on the Nozzle and Control Pump autopsy. Both were immaculate internally. Absolutely no crud, looked brand new. Tested motor on bench, ran at all speeds, up to 23 volts per spec. Anyone attempting this "cleanup" should make sure they have a 5/16" Allen wrench handy for the bypass regulator cap. I'm convinced that nothing can get past those dual fuel filters. This was very educational, but we are back to square one. I shall now do what Dick recommended and replace the ignition wires, cap, rotor, and coil, as they are all original. I have a 93 Grand Cherokee, a 93 Imperial, and a 91 TC, all have over 150,000 miles and 12 to 14 years of snow belt winters, and all I have ever changed on them were spark plugs. This 82 Imperial spent it's life in sunny southern California, but maybe the dry climate got to those high voltage parts. I've seen that happen to high voltage power supplies at military installations out there. Any suggestions on replacement components, or just stay with OEM equivalents? I'm going to take a rest and regrow my epidermis after contact with all that carb cleaner.
