I need to change the fuel pump in my 1996 SAAB 900s. I need to know the easiest way to do it. And is it easier taking off the gas tank or going in from the inside of the car under the rear seat? I realize that I would have to cut a hole in the floor to do so. Do you know where I can get a diagram of the fuel pump and gas tank?

pull the drivers knee bolster and check for water under the dash and carpets, second remove the single to-rx screw holding the relay panel in place pull it down and be sure all the relays are tight wiggle them around i have gotten bad connections here that caused similar problems also check all the connectors under there and every plug into the back of the fuse relay panel, if that leads you no where you need to get a wiring diagram for each of these circuits and find their common place such as a ground or relay power please rate i will try to find my repair cd for these diagrams -jeffbest of luck and i will be back with diagrams -jeff

Must be a seized mechanism, if it is the rear hinged type, you need to get behind the grille if you can and release the catch from underneath.

You take all the center console and plastic ducts from between the seats. There are 4 10mm bolts holding the shifter mechanism to the floor. Take these off and do your best to flip the whole housing to where you can access the bottom side. The ignition switch is attached under there. As I recall there are 2 T20 screws holding it on.

I'm afraid if you don't have the code, you will have to take it to a local dealer or specialist radio store to have it re-coded.

Fortunately, it's not expensive.

SOURCE: where is the thermostat in a 900s oh. 97 saab 900S

Oil change interval has nothing to do with operating temperature. If your coolant is full, feel the upper radiator hose, when the vehicle is up to temp. if cool , thermostat is back from that hose,

Look for air bleeds, and read owners manual, some cars have coolant bleeds. Also, heater on high when filling coolant or risk bubbles...

My thought is that your fans may not be kicking in. They should cycle on and keep temp low enough. test them.
