To check the fuel pump, disconnect the banjo bolt on the fuel rail and put it into a clean petrol resistant container, then turn the ignition key until the starter engages, a good flow of petrol will rule out the pump.

The DI unit is more difficult as you need a known good one to swap with...anyone near you with a similar saab you could borrow a DI unit from to check?

To access the fuel pump is under the wooden floor panel in the boot, take the metal cover off, disconnect the 12v supply and then undo a small 10mm bolt (IIRC) which holds the fuel pipes in, pull the fuel pipe connectors out...be very careful as they can snap! Unscrew the big plastic screw on ring and fiddle about trying to get the pump out...it does come out eventually! Good luck!

The oval floor panel is in the trunk (boot), if you remove the lining you should see it just behind the back seats.

Surely when you turn on the ignition you can hear the fuel pump prime up?

How do the plugs look :confused:

Floor Linings...you have to pry them loose from the sidewalls and completely remove. Once you see the metal flooring, you will see a silver metal plate approx 9 in x 5 inc. Held down with two bolts on each end. the pump is under the plate.

Anything is possible, however the fuel pump is not an uncommon fault on these cars. My 93's bought it and left me stranded in a side street in Rhode Island.

No.

On my 1992 car the fuel pump is not activated until the ignition key is turned all the way over and the starter engages. Just having the ignition on doesn't energise the pump. Found this out when I checked flow when I put an uprated fuel pump in.

okay so after about an hour just trying to get the round thing out, the fuel pump is in and working...but its an aftermarket so i dont know if it'll perform as good as, at first it felt like the car wanted to stall, but then it got better...now my problem is my srs light is on...why is this? i havent checked fuses yet cuz it got dark out...so what could be wrong if its not the fuse?
