I'll repeat my last post: | You may get lucky - it may be as simple as spark plugs. | This happened to me ~18 months ago. The spark plugs | were fairly new (only ~6,000 miles), correct NGK type, | gap etc. just a bad set of plugs! Once replaced, my car's | starting problems disappeared. In my case I could hear | that the spark plug cleaning was not working as it should. I can't explain it, I did the DI swap thing etc. in the end it was the spark plugs - they looked fine etc. The only clue may have been that when I took them out they came out very easily - I wouldn't have said that they were loose, I was just surprised at how easily they came out. Maybe the compression washer was flat/faulty - I know that they are only intended to do their job once. This happened long ago enough for me to conclude that it could have only been the spark plugs that caused the problem since I have not had a starting problem since. The problem was very similar to yours in that sometimes it would start fine, but at others it would take many attempts - over an hour one time. Sometimes it would 'fire' during the the spark plug cleaning operation after I had tried to start it but had failed. This told me that fuel, at least some, was getting to the cylinders. A note on the spark plug cleaning behaviour, at the time this was a half heartedattempt, a short buzz, then a silent period followed by what sounded like a relay click. Now the spark plug cleaning buzz continues until the relay click sound. One other thought, It may be the relay assembly that operates the fuel pump. I had this on a Honda Accord - it turned out to be a dry joint on the PCB assembly, easily repaired (once found) by re-flowing the solder with a soldering iron and some flux. I don't know how similar the SAAB fuel pump control is (to the Accord's), but I do know that the headlight and indicator (turn signal) relays are dogged by this problem. Good luck...
