It could be the anti-drain back valve (check valve) is stuck or it could be the Walbro fuel pump which is known to be good up to the 80,000 to 120,000 mile range. The banging on the tank trick working usually means fuel pump.
The typical symptom of a fuel pump check valve failure is extended cranking time during startup. What generally occurs here is that the check valve in the fuel line sticks open causing lack of fuel pressure. This usually occurs after the car has been sitting for a while or overnight. The fuel pressure leaks down causing the fuel pump to have to work very hard to push the fuel from the tank to the fuel rail. The symptom is similar to vapor lock but not quite. The solution to this is to replace the fuel pump check valve which can be difficult in itself. Be very cautious when attempting this repair because of the dealing with the fuel system and this always presents a potential FIRE HAZARD!!!!!!!
NOTE: When doing this job, be careful. If you break the link with no check valve in the fitting you will have to replace the entire fuel line because Saab does not offer the fitting by itself. Being a "Bull in a china shop" would not be a good idea here. If you break the valve you can replace the valve by itself only if you purchase the complete line and remove the valve from the new line and install it in the old line. They valves become brittle over time and can easily break when removing the fuel pump.
Fuel pump failures often cause the engine to buck when going up hills or just quit completely. You can test the fuel pressure using a fuel pressure gauge. The pressure should about 40 PSI (approximately). The location of the pump depends on which car you have. On the later model 900, 93, 95, and 97X the fuel pump is located in the fuel tank and the tank must be removed to replace it.

i would think the switch has failed if the seat gets hot in the off position. Either disconnect switch or fit a new switch or take fuse out.

First use Tech2 for DTC. Blahblah speach like "got a code in the 1100's" is useless ;) For me it sounds like a crankshaft sensor, but I may be wrong.. Need more info to help you.

Honda questions don't belong in the Saab area.

Malibu ?? This is Saab area.

You are in the wrong place. This is Saab only.

If that code doesn't work then take the car and proof of ownership to your local Saab dealer.

No. The engine temp sensor affects engine idle speed, and timing. There is an in car temp sensor that controls the position of the blend door and the fan speed if the system has automatic temperature control.It also cycles the AC compressor clutch and the radiator cooling fans.

if its a standard you need cluch if its automatic check trans. fluid if the fluid level is good probably needs trans rebuilt.

Take it out and look at it - still white, OK. Dark and encrusted with dirt, leaves, pollen, etc - replace.

You can either remove the motor, which will let the wiper transmission move freely to the down position. Or remove the wiper arms from the pivots. You do not want to try and force the arms down while the motor is attached as this will just bend the transmission arms and cause you a great head ache.

Here it is:
