2jzge x73 cressida (has fuel, has power, no spark?) Please help!!

[jdmsupreme2132]

Ok so pretty much ive got an x73 with an auto 2jzge from a jzs147 gs300 (not sure of year). I have power to all things necessary i.e. Ignition coil, ignitor, fuel pump etc... Now my problem is i do not have spark. I've checked over my wiring numerous times and ive also checked to see if i've missed any grounds, which i have not.

*Not to mention that my engine harness and ecu are from a Cali spec sc300 (also unsure of year) if that makes any difference.

I followed this wiring diagram:

Can someone please shed some light upon this situation?

did you bypass the NSW???

By bypass do you mean splicing pins 76 and 77 together? the STA and NSW pins?

[jdmsupreme2132]

Also, the car turns over...but just no spark.

yeap 76 and 77 to the STA circuit of your car.

if his car is cranking, the nsw is out of the equation already,


check ecu grounds, check for voltage on the harnesses, tps / afm connectors, check for power on the ignition coil connector, make sure voltage is everywhere,

that depends how he has the starter circuit hooked up, 2jzge starter wire is built in the engine harness.

Where/how is the ignitor mounted? When I first did my swap I didn't realize that the ignitor grounded through its case, I had it zip tied (I know, I know) to the underside of the intake manifold. Make sure it is tightly bolted to the fender, or you have a good ground wire attached to it.
