Suby 2001 thats great info.
I did my timing belt, water pump etc and got 3000 miles out of the car before it shut down and started showing ER HC. ( my temp gauge also goes right not HOT) as well. It won't start anymore and it died on me on the highway.
Where are your five grounds at? My two ground straps to the underside of the heads have been rusted out the entire time I've owned the car so I didn't replace them. (It ran for 60,000 miles without them, and also after the timing belt change).
But tracing back from the negative side of the battery the only ground I see goes to the starter. ( I disconnected and cleaned it last night). Where are the other two grounds? Which ones did you find that needed to be plugged in.
Still no cranking for my car even after disconnecting the battery. I'm going to try and DTC trouble code scanning tonight to see if I can get it any more info.
