HELP: 1JZ swap injector issue (no pulse)
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

You will need to move some wires around.
I had a 1JZ in my 92 SC3 everything worked 100%, a couple months last later i pulled the motor and swapped it in my 95 SC3 and it was a nightmare.
First you will need to swap the alternator, the oil level sensor and then try to match the body plugs from the 93 to the 95. GL
Check the grounds also.

excellent this is a start.
i know my oil level isnt working. do you know which connector the pin is in that i need to swap? or what color wire it is?
for the alternator... i already soldered the round (older style) connector that plugs into the alternator on the body harness. Do the pins need to be swapped at some connector or fuse box?

ok kool the fuse box is fine, the oil level is purple and red on the 93 i think not 100 sure but i can look it up for you and let you know.
It's on the long orange plug that goes to the body plug.
I will let you know tomorrow morning.

ok as far as the oil level sensor is concerned
the 1JZGTE has a purple wire w/red stripe and a brown wire w/black stripe
the 2JZGE i pulled from the 95 has the same purple wire w/red stripe and a brown wire w/black stripe
i found that the purple/red red wire on the orange harness is in the same spot between 1jz and 2jz
