Tomorrow I'm going to try to start running more test... I'll check IGF in the ignitor, also the crank and all other sensor to make sure they're communicating With the ecu
1jz injectors not firing....HELP!!!

Check IGF at the computer first how I described in the PM. If nothing, then check the igniter since you can get a signal at the igniter and none at the ECU which would indicated a broken wire. So checking at the ECU first, eliminates doing both steps.
Sorry guys had somethings come up and had to stop working on the car. But to answer your question I Was checking with a multimeter so it wasn't able to read any pulses I'll test it with a test light for the pulse. If that pulses then I'll start test continuity from sensors to ecu. I just hope I find the problem.
Well if you have spark then the ecu will have enough info to fire injectors. The only requirement to get injector signal on top of spark is IGF pulse and sta/nsw.
found my issue, the wires on the rear cam sensor were repinned backwards, i didn't know that the cam sensors polarity mattered but i guess it does... car starts and runs but breaks up at 2k and now i'm getting codes 14, 21 and 78 i'm about to looks these up.
Nice. How did you figure it out? The wire tracing I PM'ed you about? Or you had spliced in a pigtail?
the wire tracing and all i did was re-pin it correctly and good to go! but now i'm having these new issues but still a drastic difference.
latest problems have been solved!!! it was 2 of my coil connectors that were effed up and i just made sure the pins were going in to the coil correctly and after that, she was pulling hard.
