Ok, so i pulled a dumb and challenged myself to build a car in 1 week, putting a Lexus 1uz onto a w58 into a Mk3 Supra,
but I hit a major roadblock... My engine won't run, it'll crank but nothing more. I've been trying to get my engine to run for the past three days, literally have been working on it for 10 hours each day at least, and have somehow gotten nowhere.
What I have -
-I have the 1UZFE VVTi engine (I believe it came out of a 99-00 Lexus SC400) just the motor, no transmission
-I have the ECU (that I believe is the original stock ECU)
-I have the stock wiring engine wiring loom which came pre-plugged in and all that
My engine again
Wiring loom and ECU
What I've done -
-Connected the EB2 (2) wire which is black with red stripe (I believe is ignition 1) directly to the positive to the battery
-Connected the EB2 (3) wire which is also black with red stripe but physically larger(I believe the starter power wire) directly to the positive on the battery
-Connected the IJ2 (11) wire which is black with orange stripe with silver dots directly to the positive on the battery
-Connected the IJ2 (11) wire which is yellow with black stripe directly to the positive on the battery
-Put in new SAE 5W-30 oil, there is an oil leak but it has enough oil to run
top left EB2(3), middle bottom EB2(2), top right EB1(4)
What I've tried -
-Used starter fluid spray directly in the air intake, did NOT work
-I plugged in a blade fuse in the power and ground wire(i think) of the transmission plug to try to trick it into thinking it was in park because maybe the ECU wouldn't let it run, did NOT work
-Bought and connected a MAF sensor (from a junkyard Toyota) and plugged it right in without an air intake, i was told it would run without one but got one anyways because i also heard it the ECU won't let it run without MAF input, did NOT work
-Looped (plug a wire in power running to ground) O2 sensors near transmission plug, tested with and without, did NOT work
-Cleaned spark plugs for healthy ground
-Tested power to ECU, it was receiving power (12.6 Volts approx)
-Probably a lot more but writing this from my crappy memory now
MAF sensor plugged into MY engine
Transmission plug with blade fuse
Final words -
- I believe the ECU is not sending signals to the spark plugs, therefore there's no combustion, I don't know why
- I have spent hours and hours and hours on lots of forums trying to figure this out myself, obviously couldn't solve the problem
- I may just be missing something important, honestly I don't know now
- I tried to be as descriptive as can be because I know that helps others diagnose the problem
- If you have a question just ask, and I'll answer it to the best of my capabilities or I will honestly tell you I don't know
- PLEASE TEXT OR CALL ME AT 512-720-1166 IF YOU THINK YOU CAN HELP, OR HAVE A SUGGESTION

I would really like to make my lexus faster. The gs allows for some nice cosmetic work, which i've capitalized on. ( Black wrap on top, halo style Lights, planning to tint windows and add new wheels) but on top of the cosmetics I also want be faster to match the cosmetics. I plan on adding a Cold air intake as well but I really want to know if I can add a Turbo and if so what kind of strain can I expect on the engine?
So im just wondering if im seeing this right .....i have been bitten by the apparent lexus goblin ....no response from gas pedal until the very bottom and search google found this cool site and posts from as far back as 2011 i believe and although i may have missed it NO SOLUTION....plenty of remedys and band aids but no real fix and lexus has been having these same problems with their cars from 98 to i think i saw someone post about a 2011 with the problem ...and still no solutions ...really? Or did i just miss them lol
I've noticed a knocking sound from the engine compartment at cold start-up's. Gone in 1-2 seconds. Guessing is a engine lubrication problem. I run Mobile 1 at 5-7 thousand mile intervals and the 2012 ES350 has ~60,000 easy miles in the AZ. sunshine.
Is this development bad on the mechanics? Should I be alarmed?
Any idea as to a cause and any potential fixes? Recommended oil aditives?
How's that for four questions? Thanks for any assistance.
