crank position sensor is the usual go-to for saab warm/hot start problems.

B2*5's do it for laughs, i bellieve the B207's are usually more sensible. Usually.

CPS shoud be simple enough to change but it's position on the 2*5's means that you need the tiniest hands available to man to get at it. Most do it from below but i've always been able to do it from above thanks to my child sized paws.

You'd think that once you change it then your problems will be over ? Not so, it has one more comedy prank to pull on the unsuspecting fixer. there is an O ring on the sensor which often stays put in the housing. If you fit the replacement, complete with fresh O ring, without somehow hooking the old one out of its lair you will still have no start as the sensor is now fractionally too far away from the ring-gear to count the teeth properly.

the old adage about the tacho twitching or not when cranking is now known not to be diagnostic

Fuel pressure regulator has been known to produce this if it's losing pressure during the shut down.
