This is my posting and looking forward to your comments - fixing this issue.
As I stated in the title, I'm having issues starting my 9-3 first start of the day when it's cold outside. Once she has been started, she fires right up throughout the day. During the summer I have no issues starting her.
I have replaced the battery last month to a higher cold cranking amps - 730
I had the starter / alternator checked out
Tuned up the car - Plugs - Coils
I brought her into a Saab mechanic here in Atlanta to diagnose the issue. The only thing they could see that needed to be done was replacing the timing chain system, as the cheap plastic rails were broken and about to fail 100%
The same garage did a cold compression test - A valve job will need to be done in the future
- They also did a ground and draw test all coming up ok.
It puzzles me that she only struggles when it's cold outside..
* This past winter she slowly cranked one cold morning, but wouldn't turn-over - I used a battery pack and she fired right up.. This makes me scratch my head
After reading countless amount of Saab forums about similar issues, I'm seeing that it could be the:
- Crankshaft Position Sensor?
- Fuel Pressure? - I will try this today - Turning the key on for 10 seconds > off then on to prime the pump
- Could the cheap GM valves be the issue? My thinking is- It would run rough and not want to start in any weather..
Thank you for reading my post, and I look forward to hearing from the community.
