Hey guys, I've got a 93 SC400 1UZ, stuffed in my turbo 88 MKIII chassis.
I'm using a harness from a non-turbo 7m though.
Anyway I followed everything from Mike and Bryan (1uzsupra.com) and I'm getting no spark, i haven't checked fuel yet cause my lines aren't hooked up and the green wire for the fuel pump.
I've checked a for power on every ecu pin, and they all had power (liek they were supposed to) minus two of them from the D plug on the ecu (the ones for battery). Fixed that, tried to crank, and no spark.
I don't know if the ECU is working because my CEL never comes on (did before with the 2j though), but the car has been sitting for more than a year.
Anyway the coils have power on both pins (verified with a LS400), TPS (and TRAC TPS), AFM all have power.
It seems like Injectors, coil, and a few other things are on the same circuit but it all works, and it back probes to the ECU a-ok.
My main issue is being confused on the wiring, unfortunately, Mike and Bryan's wiring diagrams are vague at best, and Jake Bryeck (SP?) is even more vague.
I'm worried I don't have everything wired up correctly. On another note, I tapped the green wire to power, and I don't hear my fuel pump kicking on.
Tomorrow, I'm going to test my ignitor and ECU's on another SC400 and hopefully it starts that car. if it does, then at least I can rest easy that a part of the puzzle is solved.
Any feedback is MOST definitely welcomed.
