I need Help understanding the starting circuit

[speed]

Okay guys, I'm a bit confused. My starter is good, but is getting no voltage on IGN "Start". The Starter relay clicks, but no voltage is sent to the black/blue wire on the starter.

According to this:
http://www.cygnusx1.net/Supra/Library/TEWD/MK3/manual.aspx?S=Main&P=038

the starting circuit is a fairly straighforward circuit. Some switches, some relays, thats it. But - doesn't the starter wire go to STA on the ECU? What am I missing with this?


:1zhelp:
Again.

Please.

What happens when you run a hot lead to the start signal on the starter when installed in the car? Does it start the car?

jump the relay and see if it starts if not then its probably something after the relay causing it not to start. It's hard to diagnose ur car over the internet so search all the info u can find about it and if u can't get it then get someone to help u out in person its alot easier

Yea, thats what I was figuring. I leave for a 2wk vacation tomorrow, so I was hoping someone would say "oh yea that happened to me its _______" and voila i'd be able to get that checked off. Oh wells, I'll get back on it when I return.


Thanks for the suggestions fellas
