Setting TPS when COLD

Setting TPS when COLD
I cant find this anywhere. Yeah, you have to have a RUNNING car to set your TPS. My car doesn't run anymore. SO how do I set my TPS? I was trying to adjust it so I didn't run 10:1 at idle, but now the car won't start anymore. I was adjusting the TPS and the idle screw on the other side of the throttle body.
I took the throttle body off to check if the primary was open enough per the FSM.
Tried searching also. Almost did the TB mod but apparently that's useless for a street car.
91 turbo.
Thanks

you have to bypass/hold open the thermowax, since it pushes on the throttle, the throttle isn't at zero...

familurize yourself with the thermowax system, and it will more clear were you need to jab with a screw driver.
your tps isn't the reason your car wont crank.... you may have a lumpy idle the more it warms up but it won't keep it from cranking, .. you can even crank with it not plugged in... being that you have a turbo model, and you are modding it, it's probably low compression. just gonna toss that out there.

what he said. you can't set it cold.. UNLESS you hold the thermowax valve down.. so the cam isn't pushing on the throttle shaft...

sure, but the throttle is not closed when the engine is cold.

Ok so next question, If I completely remove the thermowax, since the throttle is now completely closed, should the car start without me giving it throttle input? I see there's a small hole in the primary plate. Is that enough to get the motor started? Or should I just remove the thermowax, test the TPS and then put it back on?

I assume you are using the voltage method to adjust your TPS? If so you should be able to do it cold. I didn't know my thermo wax was bypassed and was still able to my TPS. I then reset it once I hooked everything back up.

I have read the whole thread, theres been no reference as to what the compression is, if theres spark, if theres fuel, or if you've checked any of them. Just because its freshly rebuilt doesn't mean something didn't happen internally, or something electric isn't working right
since you had it running, drove it, and it quit running, it sounds like engine wise something happened, but being your so dead set on the TPS being your problem, which has nothing to do with cold starting, have fun chasing, I added my thoughts

It was tps. I've never heard of a motor blowing while itS idling.
