Hi,
I had this happen to me a couple times. Check your gas guage--if it's less than 1/4 full, you probably have a dead pre-pump (a.k.a. "auxilliary pump," the little fuel pump that scavenges fuel from the bottom of the tank and fills the plastic bowl which the more powerful main fuel pump sits in). If the fuel level is below 1/4 or so and your pre-pump goes bad, the fuel level isn't high enough to supply the main pump--so it can pump any fuel to your engine. Pre-pumps cost about $60 or so plus about $6 for the little filter "sock" which fits on the bottom of pump (filters out tank debris).
If that's not it (if you have plenty of fuel), then...
On these older SAABs, there is a little black plastic connector for the Hall Effect (ignition component) on the driver's side of the distributor. These connectors do not age very well and become brittle over time.
If they are struck accidentally (by a wayward wrench, for instance), they can either crack or become disconnected. Make sure this plug (has three terminals inside) is connected firmly to the distributor's outlet on the side.
Check and make sure the engine is getting both spark and fuel. It needs both to run, so if you smell gasoline (or pull a spark plug and see it's wet with gas or smells strongly of gas), I would assume engine is getting gas. In that case, trace ignition faults .
If there is no gas smell from exhaust and you have dry spark plugs, check the fuel pump for voltage while someone cranks the ignition (but you said you thought fuel pump was running).
Report back and give us an update in this same thread. Hopefully this will help...
