Question about 1993 Pontiac Grand Prix
The crank sensor on the 3.1 is on the firewall side of the engine, about halfway up the block, Difficult to get to. They are VERY BRITTLE, so take your time prying it out. You have to get at it from under the car and it is retained by one 10mm bolt. Good luck!
