Why is the TPS not plugged in?
You cant wire tie or zip tie it?
The unplugged TPS is will cause running issues.When you checked the cold start injector, did you just test it, or did you make sure it sprayed fuel when attached to the cold start timer? A bad cold start timer will require the engine to turn over multiple times before it fires up. You can test the system two ways, the FSM shows pulling the CS injector, reattach it, and see if you get fuel when the key is turned over. Another way would be to fire the CS injector before you turn the key, you can do this by momentarily applying power to the injector.
Wow... To fix my cold start issue, I had to twist my choke housing 20 degrees. It took half a day playing with an old carb to figure out, 10 minutes to do, and cost $0. Carb life is good!N.B. Swapping on a carb intake manifold shouldn't be that hard. Getting the fuel pressure right might be tricky though, but I'm sure it's been done.
If my memory serves me correctly, think it was Mudder in the recent past, that replaced his Start Injector Time Switch, that he believed was good, but the new sensor fixed his hard cold start issue.
Dropping EFI for carb is about the biggest super hack mod you can make.
I have found that even when electronic components test within specs, when near the extreme ends of their operating range, they are often the issue.
