Read this part of your post carefully, and see if you can find a correlation.
"My mechanic replaced the injectors but not the TPS, because I had to order the part. So when it came in, i replaced it myself. However my car wont start at all now.
Now ask yourself, do you think it might have something to do with what I told you yesterday?
"The outgoing voltage needs to be set by adjusting it to a very narrow range compared to it's reference signal of 5 volts input."
I'm sorry that there are people here who told you that it doesn't need to be adjusted. At least one of them didn't even know what part he was talking about. Now today, there's a guy who thinks that what you did isn't why the car won't start, when it's the only difference between now and yesterday, when your car did run. I hope you see how insanely stupid that is, and take it to a mechanic who has the specifications to set it by, and a high impedance voltmeter to do it with.
That's the best advice I have to offer.
