1995 Buick Lesabre won't start

I just replaced my harmonic balancer in my 1995 Buick Lesabre and now it won't start up again. I had no trouble with the replacement. I'm wondering if there is something I didn't do correctly or need to do after, that was not mentioned in the directions I had. I replaced it because of the loud noise coming from the pulley location; I had to replace one in an Olds 98 before for a similar noise. Is there a way to check what is wrong?

You probably damaged the Crankshaft Position Sensor. It is located behind and to the front of the balancer/pulley assembly. This sensor must be installed with some precision as there is a .025 clearance requirement. A special tool should be available for rent at your auto parts store. Sensor is around $ 75.00.

The 1995 model was a wired year with harmonic balancers and the partial changes to OBDII PCM’s. To get the correct balancer, you will more than likely need the VIN number and purchase the balancer @ the dealer. Several combinations were used for the 3x and 18x rings and even though they may look similar, some have a different ring offset. The CKPS will read either one, but he PCM will not get the correct information if the rings have the wrong offset! Many of the “China” made balancers are known to have the wrong offset rings.

In addition, the 1995 CKPS is NOT adjustable and use a dowel pin to locate. Also, the reluctor ring gaps are much wider, so therefore, the gap should not be a problem. Where did you get the balancer and what brand is it? Did you compare the reluctor (3x-18x) rings with the original? You need to check the ring gaps in relation to the hub keyway, for comparison on both balancers!
