Do you have access to air tools?

1. Undo both belts
2. Take off passenger side wheel?
3. Take off plastic shield in front of harmonic balancer/crank pulley
4. Use 24mm impact socket with an 1/2 inch impact gun to zap the bolt off/ If no access to impact use a breaker bar and rest it against the frame and disconnect the ICM and use the starter to spin the crank and break the bolt loose.
5. Finish removing crank bolt.
6. I used this kit to pull the harmonic balancer out. You need a specialized kit or properly size bolts the spec to are somewhere in this forum.

7. Once Crank Pulley Balancer is off the crank sensor is right there, but I think you have to pop off a circular plastic cover. It is held on by three studs and just pops off.
8. The crank sensor is held in by two bolts. Remove the bolts then wiggle like a MoFo because the sensor sits on a stud and after bring there for years they tend to bond. So if you are replacing the sensor just pry it off because who cares if it breaks!
9. Put new crank sensor in and don't over tighten as the sensor is plastic.
10. Put plastic shield back on and run the sensor connectors through it accordingly.
11. Put Crank pulley back on and make sure it is lined up on the crank as they are both keyed.
12. Use impact on crank bolt to press Crank pulley back on.
13. Put shield back on and belts. Enjoy car that doesn't stall anymore.

Whole job should take less than 1 hour if you have an impact and proper harmonic balancer puller.
