Yes, it will. The crank sensor sends pulses to the vehicle computer, which uses them to synchronize the firing of the injectors with the rotation of the engine. If there is no input from the crank sensor, there will be no injector pulse and no spark pulse.

Check the wiring in or close to the turn switch lever, they may be frayed and be the cause.

should be .9 to 1 in the saabs. thats what the manual says

"I bypassed the immobilizer circuit only on my alarm module (which is really tedious). Bypassing the whole module is possible (and little easier), but you will lose the use of the remotes and the ability to arm the alarm. The alarm module in my '97 900 SETC is located under the carpet, below the driver's power seat switches (a pain to get at). If you want to bypass the module completely: 1. Disconnect the battery (make sure you know the radio code-if needed) 2. Unplug the connector from alarm module and remove module from car 3. Install a wire jumper between pin 8 and pin 20 in the connector 4. Install a wire jumper between pin 9 and pin 21 in the connector 5. Install a wire jumper between pin 10 and pin 22 in the connector 6. Wrap securely with electrical tape If you want to bypass the immobilizer circuit only: 1. Disconnect the battery (make sure you know the radio code-if needed) 2. Unplug the connector from the alarm module 3. Cut the following wires from the back of the connector and splice together as follows (Don't cut the wires too close to the connector, because someday down the road you may want install a new module, so you'll have to reverse this process): 4. Cut the wires to pin 8 and pin 20 and splice together w/ wire nut 5. Cut the wires to pin 9 and pin 21 and splice together w/ wire nut 6. Cut the wires to pin 10 and pin 22 and splice together w/ wire nut 7. Secure all with electrical tape 8. Reconnect the connector to the module Not knowing the details of your problem, please be aware that this may, or may not, solve it. Good luck and let me know how you make out."

Check engine and check gearbox on an automatic...neutral safety switch is going out. First couple starts like that and it seems like it's in limp home mode...it is. A few more starts and it will reset itself. Mine did so reliably at the 5th restart until I changed it. Get a used on if you can, they are not really rebuildable reliably. Pain to change, it's under the battery tray and miserable to get to.

Tighten the dash latches , 1 turn at a time, until it goes away. They back out sometimes (until people realize this code comes on, then they are more careful)

Takes a standard sized flat battery, you can do it yourself...go to thesaabsite.com to find procedure. Basically you put the new battery in, get within 10 feet of the car and hold down one of the buttons for like 5 seconds. I have done this with my 97 900, both fobs, and they work just fine.

A code p0455 most likely means one or more of the following has happened: A loose or improperly affixed gas cap, A non-conforming gas cap (i.e. not factory/original brand) , Other leak or damaged piece in EVAP system. Make sure you click at least 3 times when closing gas cap to seal tight, and the seal on the cap may be worn...common issue. The code will go away after a bit (next test cycle) if this is it and you have tightened. The car is old...do some PM and change out the vac hoses. Less than 10 feet total. Do yourself a favor and get silicon lines, you'll never need to do it again. Takes a half hour at the most. Same deal..code will reset after next test cycle if this was the trick. Still cant get it fixed...may need to smoke test it...or blow some cigar smoke into system yourself and watch for where it comes out...change that chunk. (If you do the previous and change em all. you likely wont come to this point. If you dont...you'll be back doing this again) Worst case...your evap purge pump is on the fritz. Easy to change and not terribly expensive as Saab parts go.

4 Cylinder Thermostat Removal

1. Drain the coolant by opening the drain cock or removing the lower radiator hose. Remove the lid to speed up process2. Remove the throttle body ccover on turbo cars3. Remove the bypass hose and the pressure pipe between the Intercooler and the throttle body on turbo cars4. Rempve the screw that holds the coolant pipe to the water pump5. Remove the screw that holds the coolant pipe in the front left of the engine 6. Remove the hose to the throttle body pre-heater 7. Remove the thermostat housing and remove the thermostat8. Refit in Reverse

Grooved Idler Pulley

check the alignment of the boot lock

The linkage has broken or fallen off the motor.

Not enough info to begin to formulate answer

There is a small gear on the tonneau lift motor that has stripped out...pretty common failure. The gear is available, but an aggravation to change and some small pieces are no longer avail. Has happened to mine...get a rebuilt motor on ebay for under a hundred bucks, have your local saab guy put it in and recalibrate the roof at the same time as it has likely tweaked itself when it stripped.

The fob is probably dead, needs a battery...if your doors dont lock with fob that would confirm this, and I believe there is also a fuse for the door button...will work when car on but not when off is a blown fuse I think.

In the tank. On some, like the 97 900se, the hole and cover in the trunk for accessing the pump do not line up with the hole and float/pump assembly unit in the tank itself and the tank has to be dropped to get to it. A bit of a design oversight there...
