You have no voltage at the TPS? And you "removed" the egr and "emissions vac line" (why???).

Check the orange wire at the TPS for voltage with the key on. It should be 5 volts.

Is it?

If you really don't have any voltage there, it's because you removed the egr. The orange wire is the 5 volt reference wire the ECM sends out to the sensors to play with. They send part of that voltage back to the ECM. How much depends on what's going on. That's how the ECM reads the sensors. Anyway, the orange wire to the TPS goes to the egr solenoid first, so if you removed the wiring, you cut off your nose to spite your face.

You will have to reinstall the wiring so that the 5 volt signal from the ECM (pin 26) reaches the TPS.

Why in the world did you remove the egr anyway? I mean, it's your car, but why create problems for no gain?
