I assume you mean a 5.0 HO
No, the balancer weight changed quite some time ago from 28 and is 40 oz on late model engines
Your Crankshaft Position Sensor is located behind your Harmonic Balancer. To replace, remove your serpentine belt from the harmonic balancer. Remove your right wheel and inner fender cover. Obtain a harmonic balancer puller. Most auto parts stores will rent them to you. The puller kit probably won't have the right bolts for your 94 Lesabre. At your local hardware store, buy 3 metric bolts, M6-1.25 x 70mm. If you can get flange bolts it is better, but a fender washer on each bolt will work if you get regular bolts. I learned this the hard way. Before removing the harmonic balancer, you must remove a little inspection plate on the transmission so you can clamp the flex plate in place. There is a special tool for this, but a pair of vise grips will work nicely, just clamp them on the flex plate tightly and be careful not to damage the plate's teeth. Now remove the center bolt on the balancer, attach the puller through the three holes and slowly tighten the center screw till the balancer slides off. Once off, you will see the electrical connection for your crank sensor just to the right of where the balancer was mounted. There is a plastic cover that you must remove. With a bit of gentle prying, it will come off. Now you have access to the two bolts holding the sensor on. While down there, look just above and to the left of where the balancer was and you will see another electrical connector. That is for your cam position sensor. One bolt is all that holds it in, but it has an o-ring so if you need to replace it as well, it will also take a little gentle prying. Reassembly is everything in reverse. Be careful to align the key-way in the balancer with the key on the crank shaft as you reinstall it. Autozone.com has everything you need to know including instructions. That's where I learn. Check there for the torque specs for the balancer bolt. I think it is somewhere around 120 foot pounds.
A automatic has a flex plate and a tork converter.. A manual trans has flex plate and fly wheel...
remove engine or transmission replace flex plate (flywheel).
To my knowledge the only small block flex plate that doesn't interchange is the small block 400.
Possibly harmonic balancer or pully. I replaced battery, checked alt. and other parts. Was told it was fly wheel, but mine is automatic, doesn't have one! It has a flex plate.
your spacer plate and starter should be the same the flex plate and converter will need to be replaced
the purpose of the flex plate is the same as a flywheel. when the starter is engaged, it spins the flex plate, thus hopefully starting the engine.
You Have to pull the transmission or at least pull it back so you can reach the bolts holding the flex plate to the crank.

1st you have to test the battery to make sure it's good. if the battery is good you should check the starter to see if that works. then, if all is well, check the flywheel, or flex plate to make sure the teeth are still there. and make sure the starter pinion engages the flywheel or flex plate. if the above are good , you,ve got problems. if everything seems ok, i would take the plugs out, and put a socket on the bolt holding the harmonic balancer on, and try turning the engine over with a breaker bar. it should turn over with about 35 ft. lbs. of torque. good luck.
If it really IS the flex plate, that's a lot cheaper than other problems that could cause a bad knock. The flex plate is a steel plate that bolts to the rear of the engine and has gear teeth around it. The starter engages with the teeth to start the engine. The torque converter also bolts to the flex plate. All power produced by the engine that is used to move the vehicle goes through the flex plate. Flex plates get old and sometimes crack. When that happens you want to get the old flex plate out of there as soon as you can before it breaks completely and destroys the torque converter. A flex plate is relatively cheap, compared to a complete engine rebuild or replacing the torque converter. To replace the flex plate, simply pull the engine (or transmission, whichever is easiest), unbolt the flex plate from the crankshaft, bolt up a replacement and put the transmission (or engine) back. Of course, there is more involved than that, but it's not as bad as some repairs.
