85's have a "9th" cold start injector. It is a stand alone system that is controlled by the other temp sensor on the front of the engine, when the key is in START position only. There is a fuse for it behind the radio. The cold start injector is NOT ECM-controlled, and has no wiring connections to the ECM system.
My 85 uses the cold start injector on every cold start, even if the ambient temp is in the 90's. Fires almost too quickly.

He has really LONG cranks right now. So long, it doesn't even start. I was attempting to help him get it to start. Not make it worse.
When everything is right, the 85 should fire in less than half a second, regardless of ambient. "Right' includes a functioning cold start injector.

You’re totally right. I’m just thinking of a cheap/fast/easy way to get him going. Certainly blocking it off is not the right way to do it. At the time I couldn’t afford a new cold start injector though.

Alright as I said I would I'm back with an update after getting the vette back. New coolant temp sensor + wiring installed (only other thing I did to the car was switch back to snow tires). I tested it today (7F outside covered in snow) and the first attempt it started but stalled out which is no surprise, but second time she stayed alive which is actually pretty great from my experience. I noticed it idles a bit differently now but I think that might be a timing issue so I'll check that soon and get back to you guys on that.
