ECU pin output parameters NEEDED!

I am trying to see if the new computer I bought is screwy or I have sensors acting up so I am looking for what all the pins on the ECU measure with a multimeter.

I literally wanna know what each pin is supposed to measure in volts so I can just run out each pin and see what is normal and if any arent, then I can troublshoot accordingly..

I would love it if someone could either take 5 minutes and quick measure it at key on and IDLE.

Or if someone knows what each pin should readout that would work as well.

I have a 90 TBI so it has to be TBI.


Thanks
Dave

I can do a scan for you tomorrow. I dont have one available for mine here at work. I posted to you on the last one that you were probably dealing with blown sensors because the regulation on the sense lines were knocked when the controller fried without the links. Use a meter and check your Throttle posion sensor IAC and temp sensor. Here is a link that should help you out. Sensors, Systems, Solenoids, and Such on Chrysler cars
