Be careful what u put in your engine oil!!!!!!

Diagram of what? or did you mean diaphragm as in birth control?

Hello, if you're still having this problem it sounds like it is most likely your ignition "switch" itself. This is generally a $300.00 fix at your local Saab dealer however you can replace it yourself with a moderate level of mechanical knowledge. I'm assuming you have the encoded blocky non traditional looking "key" with a backup "traditional" key stored within. This key contains a code which is picked up by the CIM releasing the steering lock and allowing you to turn the key and start the vehicle. In Saabs infinate wisdom?? They found it appropriate to place this delicate electrical device within inches of a cup holder and high probability of being drenched in whatever your beverage at the time happens to be (usually coffee or soda). This can cause failure of the unit, requiring replacement. Are you able to hear the "click" (steering lock release) when you put the key in? Does your message center display any information? "Steering lock malfunction" "key not recognized"? I'm willing to bet that the problem is likely in this area. I do have a used (in good working condition and in nice shape) spare ignition switch and key if you determine that this is what you need. You may contact me at [email protected] or take your car to your local Saab dealer to be diagnosed.

now theres carfax but if u go online and check for recall notices or service teck bulletins these tell u if and what problems exist with a vehicle but that doesent always mean that previous owner ever took care of the problem

it doesent mean the weather it works the same if the engine hasent been rann for awhile its not at operating temp try running it till it reaches normal temp if it does not stall its your cold oxigen sensor

Its the drive end that turns the gears. You might not be able to resecure it.
