I need a CAS for a 90-93 1.6l

I'd love to borrow it and see if its the problem, but my ECU is saying its the SGT signal. I washed the engine bay yesterday and drove it home, worked on the car a little bit, moved it in the garage(engine started and ran) and this morning, i drove to the mail box and let it warm up for about 5 minutes, made a "spirited" 3 pt turn, and 20 ft later, the engines dead. I've pulled a bunch of harnesses apart, sprayed brake cleaner in them to clean any gunk off and remove water while evaporating cleanly and quickly. I left it unplugged and had brunch, can back and still have the same old no start...

So if you have one, text me at 740-478-9675
