Hi all I have a 1991 saab 9000 turbo. When you turn the key to the on position the fuel pump does nothing, but after the motor cranks for a couple of seconds the fuel pump starts working but the car still won't start. The fuel pumps sounds a little weak so it may need to be replaced. Why would the pump not start fuel pump relay or some other underlying problem?

Either could be true, if you can try a replacement known good relay (if you've got a fellow 9000 owning friend it's always handy!). There has been some talk on here that the ACC relay is the same as the fuel pump relay so if you've got ACC maybe swap them over???
