Not in front of a diagram, but the no start and no heater/wipers sounds like a description of a failing ign switch. Maybe multiple problems.

I've got a wide band installed but not hooked up yet. I need to mod the link ecu for wide band when I get home. I had a situation where I could not start and no blower and wipers didn't work. Then while driving on the highway it all started working again.....hence my ground problem diagnosis.

Intermittently, it would act like it was starving for fuel at anything other than idle and would go after much hesitation at around 4k RPM. $100 later (new Walbro pump) I realized that the fuel pump wasn't the problem. A $45 O2 sensor fixed the problem, though on my 1994. If you can cut and splice wires then don't pay $150 for an O2 sensor. Get the $50 unit and save a bundle.
