Starter not working

When key is turned to starter position I have power output through SAM unit but have no power at starter motor solenoid. Ground is good. Looking for wiring diagram that shows connectors from sam to starter as it has to be a loose or corroded connector.

Welcome to the site, there are many great threads to research here .....but, not to be a dick, but recheck every ground you can find by undoing each one and wire brushing them all....they may look good but it is a very common issue with these cars....bad grounds.  Again not to be a dick, but try...you may get a pleasant surprise...?  OR should i say a inexpensive solution...?

Again welcome...good luck.....also be very carefull when cleaning the SAM's connections, I fried mine using a plastic brush and some sensor cleaner.....static  flash and done.  There are many threads detailing the SAM issues also...bad solder joints which require resoldering and corroded plugs and pins....

Thanks for the reply "Willys"

SAM is good ,as I have 12 volts coming out of the sam unit ,when key turned to the starter position. Problem is that there is no voltage at the spade connector at starter solenoid ( if 12 volts is jumped to starter at connector, starter works) . It therefore has to be a disconnected circuit between sam and starter .

There's a rub spot where the wiring goes past or through the intercooler area I think I have read, maybe the place to search?
