Don't bother boosting if you still haven't solved the problem preventing the engine from catching. You need to remove the battery from the car and get yourself a good automatic charger.I under stand, but the issue started when I had full charged battery, I had been struggling for last three weeks to figure out the reason for not starting so I bough ELM 327 to read any faulty codes , first I received code P0007, AVguy suggested to check if the fuel pump is working , relay is clicking and I checked pressure release nozzle for any fuel coming out. everything seems okay. tonight I will ask for boost but I had feeling it will crank but it will not start I will give it try in order to illuminate any reason.
When the charging system is acting weird anything electronic will also be affected. That could just be linked to the battery issue. Did you get the battery load tested to see if it can put out full cca? A battery can show a full 12+ volt charge but when it comes time to start the car it won't be able to put out the required amount of amps to turn over the car. I would go and get the battery professionally load tested at Canadian Tire or a local shop who has a high end tester, not that analog one they sell for $30 at CT for home use. I think its free at Canadian Tire.Thanks for every one for all help I got, finally after I recharge the battery, it started immediately but I still have questions even SAAB is finicky with batteries with all modules and computer nothing indicate that the battery was the problem, and why when I connect ELM 327 I receive code P0007(Fuel Shutoff valve fault)?
