Chase the spark issue first. Maybe there's a ground off the coil harness somewhere not attached. I'm not familiar with these motors but some do have an extra ground there.

1jz vvti IS an interference engine, you can butt-fuck the valves if the mechanical timing is off. Be careful.

Alright, Im going to take it out and test for continuuity and voltage after I get the coils to fire.

Didn't see any grounds there, but I might just give power through a switch to the injectors and coils if that would work? I'll also try and pick up a working igniter to rule that out as well and trust me man I'm sure you're 10x more familiar with this engine than me, I am lost lol.

Some background on the car just in case this might help..

Six years ago the previous owner had a running 2jzgte in the car and swapped it out for a 1jzgte.. Got the engine in and the harness done by Dr. Tweak in Phoenix, AZ. Harness came back and was never plug-n-play. After sending the harness back and forth the owner gave up on it and the issue was never resolved. Six years later, I take ownership of the car.. Harness is plugged up and the swap is complete, but still with the issue. Barely got it to crank a few days ago to check compression and all is good there. Some random relays here and there that I have no idea where they go, planning on removing these and anything unnecessary and wiring it up to it's original state before I start messing with it myself. Just trying to gather information on this swap because I can barely find any information about it.

I really appreciate the help here, I hope others can take something from this thread as well.

Ew, might be time to just get a harness.

Trust me man, I want to.. badly but I have to give this one a chance and rule some things out before I drop a grand on a Wiring Specialties one. A lot of people say the 1jz ECU's like to shit on themselves too, so even if I get a new harness it still might not fire lmao lord help me
