My daughter has a 1999 Saab 9.3 turbo which had been running fine. It suddenly would crank but not start. Not even try to start. Towed it to the mechanic. The next day it started and ran fine. Took it home ran good for two days. Now it's back to not starting. The mechanic said it had no stored fault codes and started everytime for him. We are towing it back to the garage today. It has a good battery and had a whole new ignition module a year ago. Any ideas? It has right at 100,000 miles on it.
