If anyone can help me out or point me in the right direction..We are doing a 1jzgte swap into my buddys sc300 and we thought we got it done but when we turn the key it just keeps cranking but never fires,, we hooked a noid light to the injector harness and it only lights up once then continues to loose power to the injector plugs as it cranks, there is also power to the coilpacks but when u turn it over there is no actual spark, i dont know alot about 1JZ so can u help us out please

definitely sounds like a wiring problem.

lol i'm totally in tune with toyota world right now, i'm doing an aristo 2j gte in my 71 240z, an ls1 in my buddy's sc300, and the n/a 2j out of that sc300 is getting turbo'd and going into my little brother's fd rx7 :D

so i got all 3 cars to wire up, and two 2j's to build >_<

so i have lots of wiring ahead.........that's my cup of tea though so it's just time....it could be worse...

i could be my buddy with the sc300 that has to do the fabricating on all 3 cars muwhahahha :D

anyways, double check your power supply routing, and also your start signal wire on the ecu is hooked up.

if you get fed up with it, i can go over the wiring and fix the issues for you.

best of luck,

the spark could be arcing from cracked coils, check that.. cracked coils are a common issue
