I have to concur w/ Sang. I wouldn't be surprised if you dropped that money into the PFC, and it still didn't work or get you anywhere. I have no idea WTF you've done so far, but if you've swapped almost every part/sensor, and the compression/leakdown results are good, I'd have to say wiring. As puretone said, the PFC will use the stock gen3 wiring so if the wiring is your issue it still will not run NOR will it give you the proper readouts you are wanting. If it's really messed up, you could short it out as well.

We're not being douchebags, just tryin to help someone out from throwing money at a car in hopes that it'll fix something. Do what you will, they are only suggestions .

It will cost you 0$ to open up the lid to the OEM ECU and look around for obvious signs of dead-ECU, funny burnt smells, water/moisture deposits or witness-marks there of....
Jumping ship & going for the PFC, though it's a pretty damned good ECU, is not the way to go, especially if say there is a wiring issue that is causing the OEM ECU not to work. If this holds to be true and it say for instance burnt & shorted out the OEM ECU, then what sense does it make to go PFC and burn that one too? Brand spanking new 900-ish $ PFC that is killed within minutes. BTW the PFC uses the OEM wiring-harness, which sort of defeats your purposes, if it was something that came with it's own entire wiring-harness it would perhaps make more sense because you would bypass any current screw-ups in the OEM harness.....

For that same amount of money you can have it dropped at a Toyota dealer and have one of their more experienced wiring-nerds look at it before deciding anything....I did just that, and no the BEAMS was not an engine they had ever seen/heard of before....fan control pin was hax0red on it and caused it not to run.

From what I remember it was brought to some mechanic/mechanics...

I don't believe the problem to be with wiring. It ran (not well) for a while on the stock ecu. I'm not replacing the ECU because the ECU is bad, I'm intending on using the PFC as a diagnostic tool.

I did bring it to a Toyota dealer. They were not able to figure the problem out.
