My battery died in my '96 Saab 9000 CS. I put a new battery in it, and tried to turn it over. The engine kept turning over but wouldn't start. My Check engine light was on prior to changing the battery, so I had a buddy hook up his scan tool, but no codes were read. Did the computer get reset? My friend also mentioned the tach not registering at all. Indicating that the CPS could be to blame for the car not starting. He also mentioned the immobilizer. I figured i would throw this issue to you, to either confirm his suspicions, or have a different culprit all together. Thanks in advance.

Did you blip the immobiliser 5 times to reset it when you put the battery in?

I did press the FOB 5 times and reset the remote/alarm. But it still Won't start. Plus, I can hear my fuel pump engage when the key is turned to the "on" position, so I assume that is not the issue.

Well what I do, and I am kinda of hillbilly, is leave the spark plugs in the engine and remove the DI leaving that hooked up to its pigtail, get another set of plugs put them in the DI and ground the electrodes to the valve cover and turn it over to see if I have spark. The rest depends on that.

are you getting a high enough voltage reading on the dash display, and check the flash sequence alarm delay period should indicate if there is a fault.

Try jumping the car and see if it starts. You may need a new alternator and not a new battery.
