Hi all. So i took a 1uz, believe it to be a 1994. non vvti. completely rebuilt the engine, all new timing, gaskets, sensors, etc... (also all stock) Installed said engine into a full tube rock crawler with a modified a340 trans. Harness was previously cut down from another crawler so some of this I'm trying to fix from another person, some of it was myself. Info: Auto trans runs from an electronic shifter to control the solenoids. fuel pump runs off of a relay from the ignition switch panel so the ecu does not control that, fuel pressure is controlled from a standalone regulator set at about 45 psi. Diagnostic plug on engine was removed with all wires so i havent been able to pull codes. need ecu pinout help for that. 02's are hooked up to ecu as pre and post, didnt know which ecu wires were which. emissions have been deleted other than the sensor in the intake manifold on drivers side. IAC on front of engine, along with all wires were removed. Basically it has crank, 2 cam sensors, knock sensors, 2 02's, igniters, coils, injectors, afm, tps, coolant temp. tps was measured and set per spec, coolant temp sensor was tested good. afm appears to be working correctly, tried 2 of them with same result. tested spark and it does not seem to be dropping off. Problem: Engine starts right up, idles fine, and will rev up smoothly until a couple thousand rpm and then it starts sounding like a cylinder is dropping fuel/spark and gets worse with throttle until its to the point where it is cutting almost all cylinders and dropping rpm and then back up again. sounds like limp mode or the ecu thinks its in neutral. I've tried finding this mysterious blue wire for the ecu to think the trans is in gear. And all sorts of things that I have read on the interwebs to try and diagnose this. I can post a link to a google drive that i used to wire the ecm. some of them i do not know where or how to wire and that may be the problem. ecu is a 34,22, 16,28. part number 89661,50-224 also checked ecu for leaking capacitors and found nothing.
