1uz supra wont crank with key

Recommended Posts

Some of you may remember this car, I've been working on it on and off for about a year now. I finally got to working on the wiring I am using a guide I downloaded from lextreme, below I have uploaded scans of what I've been using I've done all the wires with a tick. If I put power to the fuse box the engine cranks happily but not when I turn the key Im either missing something mega or being a idiot, but I do think the problem could be the ignition in the car not my wiring. Can someone have a look at what I've uploaded and see if there is anything missing I know it's not completely done but surely it is at a stage where it should crank from the key but not start obviously.

 

The car was a TT-auto prefacelift in a previous life and the 1uz is from an early soarer I am retaining the soarer auto box for the time being. I have deleted ac and removed the hydraulic cooler setup, I hope this helps

 

Thanks in advance Scott-tt

Tried bridging the NSW? Might help you track where you've gone wrong.

 

If it starts with the NSW bridged, you've done something wrong on the starter side which should narrow down to a couple of wires.

 

I suspect you've not run a wire in from pin 7 on Supra's IJ1 (connected to Soarer's pin 6 IJ1) - These two wires need to be connected and also have a wire run into the engine bay to the EA1 plug - pin 3.

 

Have you also run your own loom into the engine bay for the igniters?
