OK, I thought I had this problem solved on a 1992 2.1l Automatic 900... it's the car my mom is driving now. It stalled on her two weeks ago, and the last time, it wouldn't restart, but the problem seemed to be a bad battery connection, becuase the engine wouldn't even turn over. I cleaned and tightened all of the cables, and finally get it back on the road, and today, the first day she drove it again, stalled and wouldn't restart. This time, the engine cranks, but no fuel or spark.
I think I've got it narrowed to the crank position sensor. It'll run for a bit, but then quits and has to cool before it'll start again. Probing the EZK module, I can see the pulses from the position sensor when it works (i.e when the engine will run), but when it won't fire, I don't see any pulses, just a steady voltage.
To rule out a bad EZK module, does anyone know if a resistance check can be performed on this type of crank sensor? The Bently manual does not list that type of check.
And if it really is the crank sensor... do these not fail that often on the 2.1l????? I can't believe the price!! EEuroParts want's about $230 or something for a Genuine Saab one, or $99 for one that I have to splice in. Even Autozone wants almost $200 for the stupid thing. At those prices, if it's not a common failure item, I might just find a used one!
