Pretty sure TRC was optional on JZZ30s. There are plenty of diagnostic documents and pics of Soarer bays with TRC out there.
Checking the crank trigger is a great first step. I also like the idea of scoping or tapping all of the sensors via a piggyback and watching them real-time. Also, you can have wiring issues that cause open injectors, such as chafed wires grounding out the injector signal wires causing them to go static. I would ohm each injector signal wire out and verify you dont have continuity to ground through the harness anywhere.

In regards to what motor he has, I was in agreeance with blk&bluJ. I didnt know that they had an option for these in any year Soarer. I am still unsure what to believe on this part, since others have chimed in and stated the same findings. I think when someone who has been around JZ motors as long as Roger, people need to take notes and possibly listen to his theories. He is super knowledgeable if people will listen to him, along with many other senior guys. I am not saying he might be wrong, but when I have a question, I call him or Gerrb personally and listen to what each of them have to say. They shed light on many other prospects that possibly I didn't think about. These two guys, along with others, have been around a long time........ I appreciate these guys stepping in and trying to help others. Like I said before and I will say it again, "When EF talks, people listen!" Only old school guys like myself, know what that means.....

If you notice the breather pipe that comes off the exhaust valve cover you will notice it is a long pipe this was a change made by Toyota to combat a problem the twins where having on the back turbo with crank case pressure and oil burn through the turbo in simpler terms it was a internal change done and signifies a later motor type than the JXZ 81 you speak of.

Not going to argue with you!! so you went to Japan,Canada,Australia and pulled this motor out of a Toyota Soarer???
Or was it that you pulled this motor out of a Lexus SC 300 here in the states cause the only 1J that came with TRC was from a Toyota Chaser or for the US conversion market as a Cressida which stopped in 92 in the US but in the Japan went till the 2000 yr = JZX110.
GL I'm out of this thread!!!
Nothing like arguing with somebody who has taken time to try and help you with you dilemma!!!.

Not butt hurt ^^^^^ just get fed up with the typical Forum BS when all you do is try and help.
It would have been some good info to know in helping him diagnosis his issue.
And just out of curiosity what rock have you exited out from behind cause you haven't posted anything useful in this thread to date so go TROLL somewhere else.

Also keep in mind that I ran this engine in my SC300 for a year then re-shelled it so it has run perfectly in the past.
Video of the half cut of the Soarer after it was shipped to the US:

I spoke with Mike (the shop owner where the car is) on Friday and the car will barely idle now. He feels its the engine harness even though it was taken out and ohm tested, and inspected.
At this point I am tired of buying parts just to find out the car is working worse. I sent him instructions on pulling codes from the ECU and he says he got a solid light. No flashes...
I don't even know what that means.

Well I guess I learned something new the other day concerning the TRC on a Soarer so my apologizes to the OP.
I will however ask you to once again check the crank trigger star located behind the crank pulley attached to the timing belt gear it does and has happened that they become loose. I personally tac weld all my cars trigger wheels to the timing gear.!!!!!!!

Thanks again everyone for the suggestions. Even if I didn't say it I have considered everything everyone has said in here so keep them coming. This is the most help I have gotten on CL to date so this is good.
