Re: HELP, after wiring harness change over no spark in 3rd cyl (supra7m2002)
Is it possible that the injector is not firing?Seems like you changed all the other components.
Good luck. p.s. if you are still having issues... email [email protected] and one of us will walk you through the troubleshooting.

Check that you're getting signal to your injectors, hook up a node light to it.
Verify you're getting spark by grounding the spark plug on the coil pack to the block and have someone crank it.
If one of these is not occurring, follow the wiring. If the spark plug is not getting spark then check the wiring TO the coil pack, ignitor and to then to the ECU.
If the injector is not getting a signal, verify the wiring to and from the injector. If you must, strip the loom and look at each wire very carefully.
