ECMlink car starts and stalls with cas unplugged. when plugged in wont start 2g 7bolt

[ncarson91]

okay so basically as title reads everything hooked up no leaks cas unplugged turns the car over then it stalls. but when i plugged in the sensor it wont crank over at all. its a 95 ecu in a 98. i did the option on link for the cas. wiring is all fine persumably its plugged in ecu right and same with the connector doesnt throw code when plugged in only when unplugged obviously. fuel is set right. timing belt is set 110% checked a dozen times. what could be going on help please.

I'm sure people are going to want to see a log of you cranking it. Do you have one?
Has the car run before just like this or is this a new startup problem?

no got a project car first time running actually figured out the ecu is a 97..... which means my cas sensor for my 98 works i changed firing order back fires up but idles at like 2k soo idk what to do now . will attach log next

Here is the log!

It's idling high because your throttle is stuck at 11%

What should it be adjusted to… 0? Sry I’m super new at this

Check the throttle cable. Is it too tight? If yes loosen it a little from where it bolts to the intake manifold. If it’s loose, you’ll have to look at the throttle body or tps is way off.

Watch these and follow. These are the preliminary thing that must be done before touching any buttons on your laptop.

Usually a high idle like that it due to mechanical issues like a tight throttle cable, mis-adjusted idle stop or BISS screws, Defective FIAV or ISC/IAC, or vacuum leaks.

It's been a long time since I've diagnosed idle issues. Above 1500 it almost has to be mechanical?? Unless ecu doesn't know the throttle is closed from bad idle position switch (1g) or test issues on a 2g? Otherwise at 1500 ecu will cut fuel and you get idle surgw instead of a 2k idle.

Either way first I would check is cable.

i was just discussing that exact topic with some one last week, but i cant remember who...... oh well.
Glad to hear you got it running, get the tune worked out and you 'll be rolling
