Ignition... completely lost

[LeonDaneko]

a couple of days ago, I was driving along and suddenly there was no throttle response... but only for a second or two, all the lights, accessories, everything else was fine. then the power came back and she was running as good as normal... a few hours later, I'm idling scrolling through my phone after work. same thing, but the engine came back before the rpms dropped to zero. Then after a show later that night, i gave a friend a ride home and same thing but it never came back. I popped the clutch going down a high grade hill and nothing. got it towed home and peeled away the 'hood' and today I did the following (required a tune up anyways) after looking through this super resourceful website as I have to make repairs in the past. (thank you to all who contribute.)

Replaced
- spark plugs
- plug wires
- Ignition coil (you can get these from toyota forklift dealerships still as they still have 4y's)

cleaned and inspected
- TB
- TPS
- ignitor (no bubbling or burning in the epoxy or corrosion on solders)
- Air Flow Gate Sensor
- air box
- vacuum lines
- all fusible links behind ps reservoir
- all fuses


the only improvement I have gotten since yesterday is now I have fuel where I didn't yesterday (tested the pump yesterday with the tester and it was good but not delivering when key turned to start.)

this all happened after a car wash.

all accessories still work. all functions still work but no spark.

any help is much appreciate.

thanks,
Leon,

I see you inspected the fuses, but did you check if there is power on them? I would start with the 7.5A IGN fuse. it should be powered if your key is turned to ignition. If it isn't check if power exits the ignition switch (I think black-red). In fact I would assume that all fuses would be powered when it is on ignition, so it is an easy check with a test-light or multimeter.

Did you check your distributor cap and rotor? You may have gotten water in there during the car wash, especially if your distributor cap's rubber gasket is old/damaged/missing.
