Default 95Lesabre Harmonic Balancer & Crank Sensor

Hello,

Just removed old Harmonic Balancer on my Lesabre with 3800 V6. Had a fun time with the crank bolt, especially since I don't have a good impact wrench. Had to lift car up pretty good to get enough radius with my breaker + cheater. HF combination Puller kit did the trick. The car has been starting and running great. Do I need to make any check of the adjustment of the crank position sensor before I put the new balancer back on? I'm wondering if there is a gap setting I need to be aware of? Can't find any mention of the setting for this one, please forgive me if this has already been discussed.

I have a 95 Olds 3.1 so we are alittle different, my sensor behind the balancer has no adjustment also! But i'm wondering about it now because i'm have problems and cant find the cause. cam/crak error po341

I looked at the sensor I took off and it looks like 1 of the mounting holes has been wollered out to adjust it. Whats yours look like?

Heres what mine looks like. Its a different animal. I'm wondering what the best way is to remove the ring that holds the key in place for the Harmonic Balancer? The key looks good, but I think its prudent to replace when you replace the Balancer?

This write up might help you. https://www.gmforum.com/mechanical-134/change-crankshaft-position-sensor-279066/

I use a screw driver to GENTLY wiggle the guard off the studs. Don't go crazy on it or you will break it.

here is my post. Could you tell me if the CPSensor could be my problem, pls???1995
LeSabre 3.8 FWD starts fine, runs 1 sec then quits. No sputtering missing noise or other indication. I had a man look at car. He went to the "Maxifuse/Relay Center" under hood, firewall and he fooled with some relays and like generally jerked the wires around. Car cranked and ran a couple of times for a minute or so , no roughness etc. ran great. BUT that was it. He never came back. Being on SS I could not afford a large repair bill. There are 7 gray 4 pin relays and 1 black 5 pin. I put a new black relay in. NO DIFFERENCE. I don't know if relay is even the problem. I have no idea of what each relay is. Or, if the black relay is FPRelay there is no label under cover. Some one said pink and gray wires are usually associated with FP. Blk relay has them ON THE relay coil.
Any help greatly appreciated!!!!! IDEAS or Relay layout diagram.
