Customer Question

had multi quirky electrical issues, changed out the eco with a new calibrated one and now it starts right up but high idles and shuts off immediately
JA: How many miles are on the car? What size is the engine?
Customer: 13100....ECM not eco
JA: What is the model/year of your Saab?
Customer: 2006 97x v8
JA: Are you fixing your 9-7X yourself? What have you tried so far?
Customer: yes, thought at first I had a short/ grounded circuit so ran multiple circuit tests to no avail. everything randomly came on or didn't so I installed new ECM and finally it starts and the gauges don't flash etc but now it only starts and won't stay running
JA: Anything else you want the mechanic to know before I connect you?
Customer: not that I can think of

Hello and welcome to JustAnswer!

If it starts and dies immediately then I would first suspect that the replacement was not programmed to the vehicle and it's shutting off due to security. Was a dealer scan tool not used to program the ECM to the car once it was installed?

Customer: replied 3 months ago.
no it was not. the advertised ECM stated that it was pre programmed
Expert:  sprinkles08 replied 3 months ago.
The software would be programmed but it isn't possible for the security functions to be programmed until it is on the vehicle. A dealer scan tool is going to be necessary to program it now.
