Don't waste your time with the battery fusible link. The fact that you have power to the horn etc means it is okay.

If its not the AM2 fusible link, then check that you have power to the junction box by honking the horn, checking the dome light works, or turning on the headlights. Better, yet, do that first then check AM2.

If you really don't have power at the EFI fuse which also powers BATT (and B+ through the EFI main relay) then you need to work backwards, and there isn't that much backwards to look at. Check to see if you have blown fusible link AM2. This also powers the ignition circuit. Failing that all...

What do you expect?...... "he's bad, he's nationwide"

Nah, those numbers are fine. Did you measure them at the ECU connector, or AFM connector?

Both errors often means the wiring is bad. I'd start with that.

Here's my PS setup http://www.supramania.com/forums/showthread.php?152272-power-steering-issues&p=1836082&viewfull=1#post1836082

LOL. Nick's getting more philosophical as time goes by.

Say what! Sucked in again....

It has been demonstrated many times that 440s and a Lex AFM will work without any leanness issues. The ECU has enough fuel trim to handle it. The only tangible risk is that at high boost you will max out the injectors before fuel cut, but that is debatable too. I don't advocate this setup, but...

Different problem. OP can't rev in neutral.

There are multiple holes in the pulley and camshaft. Both need to be correct.

Compression test won't tell you anything about the oil control rings. Neither will a leak down. Why the turbo? And what does the injector size have to do with anything? This is quite a thread indeed!

Current flows in a loop and can be broken at any point. There's lots of common power feeds on this car. You need a meter and a plan to solve your problem. Do you have either? Posts 5 and 6 should be your starting point. http://www.cygnusx1.net/Supra/Library/TEWD/MK3/manual.aspx?S=Main&P=032

If its rev limiting at 3000 rpm then there should be a code 31. Check codes again.

Most probable cause, esp given its just been rebuilt, is the timing is off. You need to first validate that the timing pulley has not slipped. That is done with a chop stick in the sparkplug of cylinder 1 or equivalent. Then check the cam pulley alignment is correct using the marks on the...

Assuming the oil consumption is high, and this is defined as qts/mile oil consumed (not colors of smoke and other vague attributes), then there are a number of potential culprits as outlined in the TSRM here. You cannot just jump to the turbo or the rings or whatever, you need to first diagnose...

Does the sensor get hot from the heater if it is removed from the manifold but still plugged in?

It's possible. but rare. What three wires did you run.... HT, OX and ?

Yeah, that wasn't clear. Toyota gasket looks like the Cometic and blocks the passages, as does everything else except the Titan. My memory is that the head has the full passages, so it may not make any difference then as there would be nothing to squeeze the gasket even if it was filled.
