This is a project that was just fired up. I did the rest of the tuning, but am stuck at the problem at the TPS. The TB is a new edelbrock 70mm. This reading of around 5 volts at closed throttle is way out there and cannot be adjusted for. What is going on here?

tps is bad or you have a bad or missing ground for the fuel injector harness.
it should read 5volts at wide open throttle, around 1 volt at closed.
are you testing the green lead wire for the tps to a ground, like the thrrottle body housing?

You either have the fuel harness ground disconnected or you are checking the orange wire of the TPS...
