hello everyone, ive been browsing the forum for a while and i post a lot on some of the other toyo/lexus forums. Right now i need as much help as i can get with a swap im trying to complete

OK so i just finished swapping a 1JZ into my 1995 SC300, and now im attempting to diagnose a no start issue. This exact same engine was running in a 93 SC300 perfectly before i pulled it and put in in the 95. No pins were swapped/changed

heres what I have
1991 SOARER 1JZGTE AUTOMATIC
swaped into
1995 SC300 AUTOMATIC

the injectors have been replaced with 440cc JDM 2JZGTE injectors (they were cleaned and flowed by witchhunter)

The car has spark when the plugs are pulled and grounded

the rail is getting fuel and is being pressurized

the cylinders and plugs are bone dry when pulled after cranking

the plugs that plug into the injectors are receiving: (voltage measured by grounding one pin to body)
with key off pin->body voltage reads 0v on both pins
with key on pin->body voltage reads 12v on both pins



im looking for any kind of ideas, or any wiring diagrams that might be useful

I had the same problem with the " Plug and Play" 440's. They didn't work so I put the stockers back in and it fired right up. I now have a resistor pack with 550's but havn't put them in yet.
I never figured out why the 440's didn't work, the impedence was only 3 ohms less.
Drop the stock injectors back in and see if it works for ya.
