1992 4 runner electrical issue 3.0 v6
I had new tires and a idler arm replaced. The truck ran fine the shop called today it won't start. You can push start and it will run. No inside light including dash, no rear light, no heater fan, windshield wipers or clock. The door lights are on, and headlight work. After driving for 10 minutes all turned on. Turned off the car same symptoms as before won't start. Have power from the battery and cold start relay is working but no ignition. Any idea's

Check the alt and AM1 fuses in the fuse block under the hood. (Headlights are powered before these fuses.) Use a voltmeter; just looking at these fuses can be time consuming and non-productive.
Fuses don't correct themselves after driving, so I'd also use a voltmeter on the ign fuse; this might help you find an intermittent connection inside the fuse block.

Yep, as Scope says ^^
However, I'm confused...
Meaning it will not crank but has ignition, so it runs.
Meaning this time it cranks but no ignition, meaning no combustion, yet it runs?

I gotta wonder if your mechanic was clueless about the Toyota Ignition switch and left it on the whole time it was at their shop .
This used to happen all the time at the local shop I used for inspections young trainees who would leave after a few months when a raise was not offered.
Draining the battery to the point it will not crank but lucky the computer did not go into hibernation mode to protect it`s self.
Driving brought system voltage up enough to power every thing while running .
trickle charge for 24 hours see what happens.
Measuring battery voltage I would say it would be under 12 VDC

Did you do as Wyoming suggested^^^? Did you answer our questions?
Your mechanic has no clue. You can take out the ECU and would still have "inside light including dash, no rear light, no heater fan, windshield wipers AND clock".

I gotta wonder how a no crank issue leads to a bad ECU
I gotta wonder how a mechanic can`t figure it out.
I can only guess the new tires no longer provide enough power to the vehicles electrical system in some alien physics way unknown to the rest of us.
New Tires and a idler arm tied into the electrical system in some unknown way .
Very Interesting !!!
